detectives say a deadly explosion that rocked an indianapolis neighborhood, leveling homes, it was no accident. >> a major development in a homicide investigation and why police have only a few clues. it's tuesday, november 20th. >> announcer: from abc news, this is "world news now." welcome to "world news now," everyone. i'm paula faris on this tuesday. >> indeed. i'm rob nelson. we'll get to that major development in indiana, ten days after the fatal blast. the story seemed weird from the beginning. now to know it could have been intentionally set, unbelievable. we'll take you to the mideast as well this morning where civilians on both sides of the deadly conflict between hamas and israel spent another night in fear. we'll have the latest on the demands to end the brutal fighting there. also this half hour, teenagers obsessed with their bodies. why some will stop at nothing to get pumped up and ripped up. the warning signs and advice for parents, however, before it's too late. i mean you always -- it's good to see teen ablers are really taking afternoon investment in their bodies and working out. but some of the o'things they're doing to get the bodies are worrisome. >> people go to extremes. nothing in the extreme is good. the story clearly will point >>. nothing in the extreme is good. the story clearly will point that out. stay tuned for that. then later he won a long list of award at the big amas over the weekend and now justin bieber is getting more attention because of his love life and the scene that he made in public. we'll have the scoop coming up in "the skinny." >> uh-huh. but first a frightening new twist this morning in the deadly blast that leveled a neighborhood in indianapolis. >> authorities now believe the explosion that killed two people and left dozens of homes in ruin was no accident, and now they're tracking a possible lead. here's abc's pierre thomas. >> reporter: the aftermath looked like a war zone. houses ripped apart in a massive explosion, the police initially thought was a horrible accident. >> the house shook, things fell, and we ran outside. we just see the whole hoss -- i mean like a -- four or five houses down from us just completely engulfed in flames. >> reporter: authorities are releasing new details, suggesting the natural gas explosion that left two people dead may have been murder. >> based upon those interviews and the results of the search warrants we can confirm tonight that there is an active homicide investigation in this matter. >> reporter: there have been reports of a white van near the home before the explosion. police have been conducting interviews and searching homes in connection with the tragedy. >> specifically if anyone has any information about a white van seen in the subdivision on the day of the explosion and about the only pants on the van, we urge you to contact crime stoppers. crime stoppers is offering a $1,000 reward for information leading to an arrest in this case. special agent in charge, robin shoemaker of atf, authorized a reward up to $10,000. >> reporter: 34-year-old john longworth and his wife jennifer were killed in the explosion that leveled two homes and severely damaged dozens more. >> today i went to the funeral mass, and during that mass i was having trouble within myself coming to a sense of peace and reconciliation. i could not even imagine what the families are going through if i could not do it. >> reporter: it is unclear what the motive may have been for such a horrific crime, and police would not say if they have identified specific suspects. neighbors left behind are stunned wondering who could do such a thing. and worried it might happen again. pierre thomas, abc news, washington. what a chilling turn in that case. and important legal note to pass on. under indiana law, a murder charge could be filed in connection with the death -- at least two deaths in this case, if they find the explosion was the result of arson here. they do find the person responsible for this, they could be charged with murder. >> and the cruel irony of the timing of this, the revelations just came to light just hours after the couple was laid to rest. and just to let you know who they were, he was an electronics expert and a nature lover who liked to garden. she was a teacher who knitted gifts for her students. hard to imagine anyone would target such a loving and likable couple. >> heartbreaking story on a lot of levels. >> well, we turn overseas now, where the fighting between israel and the palestinians enters its seventh day. nearly 100 rockets were fired yesterday from gaza into israel. the palestinian death toll from israeli attacks has reached 111, including 56 civilians. now, three israeli civilians have been kill and dozens wounded since last week, and nerves, they are on edge. >> reporter: over 500 rockets, morta mortars, and missiles have been fired at the israeli civilian population. the minister of defense instructed the idf to be ready and prepared for all options. >> israel says since the beginning of its military operation hackers have launched more than 60 million attempts to disrupt various government websites but were only successful in knocking out one site for a brief period. meanwhile intense negotiations are underway at the u.n. and in egypt to finally reach a truce here. we asked abc's christiane amanpour in jerusalem, where diplomatic efforts now stands. >> reporter: the gang of nine are meeting the prime minister and senior advisers and cabinet to try to figure out how to respond to a proposal put forward by egypt. so the effort is really under way to have a diplomatic solution. whether it works or not we are waiting to see. all the american efforts are going through egypt, when it comes to hamas. they're taking the lead. from what we understand, egypt wants to have a cease-fire, then a bigger negotiation about lifting the siege of gaza. hamas wants that all to be part of one agreement. and israel wants to see a stop of hostilities, no more rockets into israel and doesn't want to link that to a cease-fire. so those are the parameters. how they get close together to make a success of this is really what's under way right now. >> thank you, christiane am afternoon pour, reporting from jerusalem. the "l.a. times" did a great story on this, summed up the heart of the conflict here. and it says -- any sort of agreement much overcome huge obstacles. israel views hamas as a terrorist organization. and the islamist militant group refuses to recognize israel's right to exist. that is the fundamental barrier between the two, above and beyond the daily fighting and violence there. >> and in washington, they believe that if the rockets continue from gaza into israel that a ground invasion may be launched to stop the missiles. if that does happen then, hamas will risk a ground invasion that really they will completely be overdominated. >> the thing is the political chief for hamas had harsh words as recently as yesterday for prime minister netanyahu, calling him a child killer and a murderer. we see the civilian death toll climb up. talk of a truce, also harsh words flying in the middle of all that. talk of peace. so again we will follow that throughout the day and coming days to see if there is a resolution. moving on this morning, most major asian stock markets traded higher in reaction to a powerful stock surge on wall street. traders were buying yesterday amid talk from washington that a deal to avoid that so-called fiscal cliff could be reached by the obama administration and the congressional republicans. the dow had its best day since early september. it climbed 207 points. to use a phrase from monte python, hostess

passed 100 with many civilians, women, children, among those killed. abc's alex marquardt reports from gaza city. >> reporter: a massive explosion as israeli air strikes pounded gaza. [ explosions ] while militant rockets flew into israel. and amidst it all, this, tiny bodies of the dead as they left the hospitals, carried through the crowd to their funerals. >> translator: we asked all the militant groups to respond to these massacres, this man said. we shouldn't talk about a cease-fire at all. >> reporter: they were killed sunday by a missile that obliterated their three-story house. killing nine from a single family. israel said it was an accident. in southern israel, 3-year-old karen plays with her tricycle until sirens sound. her family rushes down to their bomb shelter. eight members of the malka family huddling together during the explosions. when the sirens sound, you have just 30 seconds to get to the shelter. so families don't leave home. schools and businesses are closed. but back here between the boxes, children were able to get outside and smile while others hoped for quieter times. >> we need peace. we need peace. if they stop, if israel stop, i am sure they will stop. >> reporter: of course, it's not that simple. both sides say they want peace but blame the other for preventing it. while many hope for a peace deal, the missiles keep flying. alex marquardt, abc news, gaza strip. >> thanks a lot, alex. developing news overnight, we just learned that secretary of state hillary clinton is now heading to the middle east tonight. >> not a preplanned visit. all because of this unrest. our coverage continues with lama hasan live in jerusalem. lama, what can you tell us about clinton's upcoming visit and calls for a truce. >> reporter: well, good morning to you. yes, you're absolutely right. secretary clinton, she will be arriving in the region. she is due to arrive tonight. there is definitely concerted effort for, for various players, for diplomacy to work, rather than go into the ground invasion. of course, we've seen the tens of thousands of israeli troops that have amassed on the gaza border. so i think what they're trying to do is they're trying to go down this diplomatic route. there are a lot of talks taking place behind the scenes with the united nations secretary-general moon, in cairo, and egyptian president, he is spearheading these talks between hamas and israel. the israeli cabinet overnight had a four-hour meeting to discuss the egyptian proposal for a cease-fire. so they've decided for now to continue with the diplomatic efforts and hold off the ground operation. now, in terms of some of the demands of both israel and hamas, just to give you an idea what they want, israel wants hamas to stop firing rockets. so they don't want any hostile fire of any kind heading towards israeli city. on the other hand, hamas wants israel to stop target assassinations, and they want the siege lifted

news, depending on your point of view, news for folks out in san francisco, governor body of city is going to vote on an ordinance in the city by the bay that would prohibit nudity in most public places. a blanket ban. make sure everybody covers up. they're saying here that the proposal, which is made by scott wiener, one of the supervisors, illegal for a person over age 5 to expose his or her genitals or anal region on any public street, sidewalk, street median, park, plaza, or using public transit. >> could you get a little more specific? >> people, walk around showing off their kibble and bits. trying to crack down on it. they're going to vet today. apparently prompted a lawsuit. so on, so forth. there could be like a fine. and even on the third offense under the new law, it could be punishable up to a year in prison if you're a repeat offender. >> wow. say no to crack. >> say no to crack out there in san francisco. possibly. man! i want to illustrate a very unhealthy mother/daughter relationship. it happened in chicago back in october, early october. apparently a pregnant woman helped her assailant attack her mother, they shot her with a stun gun up to 15 times. they were after her diamond engagement ring. it was 3.5 carats, worth $40,000. all right. so not only is this, this is the daughter. pregnant at the time. helps assailant beat her mom up. they made way with -- made out with $200 in cash plus the 3.5-carat diamond engagement ring. a witness was able to pull off her ski mask before the duo sped off. how about that? your own daughter, pregnant daughter beats you up, after the engagement ring, the mother is okay. treated for some injuries. still. >> thaw thought it was going to be a lindsay lohan story at first. lindsay and her mom going at it again. can't believe it. >> don't think she will be invited over for thanksgiving. >> no. awkward dinner discussion there too. speaking of awkward, guess what they turned into a musical in germany. yes, "rocky" now a musical in germany. just opened up there. with the backing of sly stallone himself. they have brought the musical to stage. taking a look. it clearly focuses on the rocky/adrian romance. so that's -- the gist of the whole thing. very, very cool. rocky from 1976. canned believe he was that old. here is a musical. >> yo adrian. >> that was? >> the new york accent. >> yo, a this morning on "world news now" -- push for peace. with dozens dead and a week of fighting there is more pressur this morning on "world news now" -- push for peace. with dozens dead and a week of fighting there is more pressure on hamas in israel to stop the violence. >> who's demanding diplomacy while civilians spent yet another night in fear on both side of the border? it's tuesday, november 20th. >> announcer: from abc news, this is "world news now." good tuesday morning, everybody. i'm rob nelson. >> and i'm paula faris. we will bring you the latest in a very unsettling night in the middle east. that's our top story. and then what a bombshell. really no other way to describe this bit of news. decades after o.j. simpson's acquittal on the murder of his wife and her friend, there is a major development, but is it a credible one? >> oh, man. this case will not die. folks will have a lot of opinions on this one. man. stay tuned for that. also this morning, gearing up for the busiest travel day of the year today, which aaa says is tomorrow. tomorrow find out what time might be the most hazardous of all the travel if you're among those hitting the road for thanksgiving. >> yay. >> so have fun with all that. i'll be here. you're traveling. >> it's allegedly going to take us 3 1/2, 4 hours without traffic. i'm saying maybe 7 1/2. >> pennsylvania. >> not bad. good luck. >> we'll pack plenty. cheetoes and mountain dew. later, what could be a tremendous advance in treating paralysis? a weiner dog can walk almost normally after losing movement in his hind legs. the medical miracle that could bring help to so many with paralysis. so not a story that's just affecting animals. we're talking about how it can translate to human beings. >> aw, sure. you never want a weiner that doesn't move. but first, it's been one week since israel launched its attack on targets in gaza. more than 100 palestinians have been killed. many children are among the hundred injured. >> the rockets kept civilians scared on beth side of the border. diplomats in the mideast and here in new york are working on a truce. abc's t.j. winick has the latest. good morning, t.j. >> reporter: good morning, rob and paula. with heartbreak on both sides, israelis and palestinians stand on the brink of an all-out ground war. israeli air strikes continue to pound gaza, igniting massive explosions, incinerating buildings and homes. the death toll has soared to over 100 in gaza, and there is payback. this video issued by hamas, the islamic militant group that rules gaza shows several rockets being fired toward israel. hamas fighters have fired hundreds of rockets into israel in the current round of fighting. >> over 500 rockets, mortars, and missiles have been fired. the minister of defense has instructed everybody to be prepared for all options. >> reporter: families have been forced into shelters. >> it's very scarey. we can't -- we can't go to school. >> reporter: but the leader of hamas rejected israel's demand that the militant group stop its rocket fire into israel and said a cease-fire was conditional on israel lifting its blockade of gaza. >> demand should be met to stop attacks and israeli killing and to lift the siege of hooligan attacks on gaza. the israeli prime minister, benjamin netanyahu said his government is preparing to ramp up military operations. president obama has been in contact with leaders in the region, also working to stop a ground war. >> as we have said again and again, we want to see in leaders with influence use it to help the parties de-escalate. >> an israeli air strike on a gaza media center on monday killed one of islamic jihad's top military commander. the group said it was the second strike on the building in two days. rob and paula? >> thank you. increasing pressure on egypt and how they kind of potentially brokered piece here. senator lindsay graham gave an interview and said, egypt, watch what you do and how you do it. you're teetering with the congress on having your aid cut off if you keep inciting violence between israelis and palestinians. pressure on israel and hamas. and with the u.s. threatening, you know, to possibly cut off aid dollars here, that kind of muddies the water even further, putting pressure on egypt itself, who is trying to build a new democracy in their country. >> and hamas is maintaining they're staying steadfast as to what they want during the cease-fire talks. they won't end rocket attacks unless israel decide to open up that blockade, but then israel doesn't want to open up the gates to that border because they don't want weapons to come in and those weapons to get into the hands of people that obviously should not have. but interesting. they say that israel is placing all the blame right now on hamas. they said that they bare responsibility for the deaths of civilians because terrorists are using civilians as shields. and really this rocket attack, rocket approach is really their best hope because if israel decides to go attack with the ground game, it's not good for hamas. >> all bets are off there. we'll be keeping an eye on the situation throughout the morning. sticking with news overseas, president obama is in cambodia this morning, the last stop on his historic visit to asia. mr. obama has a full day of meetings as part of the east asian summit there and meets privately with prime minister of japan and president of china before heading back to washington. mr. obama is the first u.s. president to visit cambodia, and he used the opportunity to challenge its leaders on hue manner rights. and we have new information about a deadly blast that leveled a neighborhood in indianapolis. 34-year-old john longworth and his wife jennifer were killed ten days ago. this morning their deaths are now called homicides. investigators believe that the natural gas expression that destroyed or damaged dozens of homes may not have been an accident after all. police are now asking for help finding a white van that was seen in the area shortly before the blast. >> specifically if anyone has any information about a white van seen in the subdivision on the day of the explosion and about the occupants of those vans, we urge you to contact crime stoppers. >> no word on a possible motive or the cause of the explosion. now the new information came just hours after the two victims, the husband and wife, were laid to rest. well, after almost two decades, we still have not heard the last of the o.j. simpson murder case. a new documentary suggests that simpson's ex-wife, nicole brown and ron goldman were actually the victims of a serial killer who confessed to the murders. glen rodgers is on death row in the state of florida, and he claims simpson hired him to break into brown's home to steal jewelry. simpson, who, of course, was famously acquitted in the case, now serving time in nevada and robbery and kidnapping, extending from a confrontation over some of his sports memorabilia. >> he even gave police a few receipts as evidence that he was in the area at the time of the double homicide back in june 1994. interesting twist there. >> reopening that nationwide debate. >> yes. and just as millions of us start hitting the road for thanksgiving, a stunning report from california. it says more drivers in that state are driving under the influence of drugs than alcohol. the state says of the busted over recent weekends, over half have been using marijuana. legalization advocates say no one should drive while impaired. they point out the risks of driving high are substantially lower than use offal alcohol and some prescription drugs. a nasty storm ripping through the pacific north west is now being blamed for at least one death. drenching rain, brought traffic to a standstill in seattle, stranding drivers and forcing street closures. aside from the flooding, the area is getting battered by winds as high as 114 miles an hour. road crews in oregon are scrambling to clear downed trees, and by the time it's over, more than 2 feet of mountain snow will be on the ground. and that storm is hitting during the busiest travel time of the year as americans head out in droves to spend thanksgiving with friends and family. 43.6 million of us will travel 50 miles or more, and 90% will drive. abc's alex perez has some survival tips to ease the way to your destination. >> reporter: reena wengard is a thanksgiving week travel pro. she and the kids are making the two-hour drive to see loved ones in indiana to avoid the mayhem of motorists later this week. >> it can get crazy. trying to get off in the rest areas, it's just people everywhere. >> reporter: the wengards join some 239 million others clogging roadways this holiday. and as the stress on the roads begins, some relief at the pump. gas prices down 5 cents in the last two weeks. but thanksgiving, carves out a week of worries on roadways. with all of these families getting in their cars, the number of incidents will sky rocket this week. so here are a few things should look out for. like traveling on unfamiliar roadways. not knowing the lay of the land could be disastrous. >> plan your route so you are not fumbling with gps, directions figuring where you are trying to go leave the navigation if possible to a passenger. >> be mindful of the clock. 5:00 to 7:00. rush hour high risk hour. there are 20% more fatal crash hours during those hours on thanksgiving week than other weeks. also keep your eyes peeled for more deer in the headlights. november is the middle of the fall mating season where the animals tend to roam. experts say the best way to maneuver the road this week is a lot like fixing a thanksgiving feast, slowly and with lots of prep work. alex perez, abc news, chicago. >> good luck to all of you hitting the roads and airports. >> thank you. >> for the holiday. >> i'll do a phoner with you in traffic for almost 25 hours. >> almost there, hour 16. you know it is time for thanksgiving when we are getting ready for the white house turkey pardon. they had a big send-off event for the two lucky bird at their farm in virginia yesterday. >> you make a pretty good cackle, bird impersonation. >> not a turkey though. >> sorry. the turkeys that went to washington each weighed 40 pounds. two of them make the trip just in case one gets ill on the way to the white house. >> they're always thinking at the white house. president obama will pardon one of the birds tomorrow, and then both of them will be taken to a farm at mt. vernon to live out the rest of their days, not on your table but in peace. i like that. that goes back to george bush sr. back in '89. they do it every year. it's a fun, cute little thanksgiving tradition up there on the hill. not bad. >> not bad. >> for the bird. >> waiting for you to do the cackle. >> it's not a turkey. i told you that. coming up, the retailers are trying to outdo each other for a day after thanksgiving tradition. why women seem to take the fall when they get caught in high-profile extramarital affairs. why is it always the

a double standard when it comes to extramarital affairs. and abc's david wright has that story. >> reporter: a general and his biographer, a washington sex scandal juicy enough to bring down america's spy master. the humor and criticism came mainly at the woman's expense. powerful men do pay a price for sex sandals. in petraeus' case, it cost him his job and possibly a bright political future. powerful men can hope for redemption. >> i did not have sexual relations with that woman. >> reporter: bill clinton's scandal may have wrecked his presidency. but eventually he got to become the elder

good names in part by accepting financial responsibility. feminist naomi wolf who just published a new book on women and sexuality says she doesn't condone adultery. >> i don't think it is up to me to

interestingly, allred suggests paula broadwell nay not have taken enough heat for the scandal which expanded to include jill kelley and twin sister natalie. >> what was that something that paula broadwell was doing with jill kelley? was it warranted? was it not warranted? did she go about it in the right way? did she not go about it in the right way? there are just many questions. >> reporter: one day after our interview, allred, announced that natalie khawam, jill kelly kelley's sister, is now her newest client. i'm david wright in los angeles. >> wow, gloria will have the press

advance holds promise for people. you're watching "world news now." >> announcer: "world news now" continues after this from our abc stations. now a miracle of modern medicine. dogs paralyzed able to walk again after cells from their nose were transplanted into their spine. >> the study is the first to show that nose cells can actually repair damaged spinal cords. the bbc's fergus walsh explains how it works. >> he was effectively a crippled dog. he had no rear leg function. he dragged his feet around. but now he can stand, he can get to his feet, he can walk. >> reporter: so how was it done? researchers removed specialist cells from the lining of jasper's nose, cells known to regenerate fibers in animals and humans. these were grown in a dish for several week and injected into jasper's damaged spine. the nerve connections regrew enough to allow his front and rear legs to reconnect. but the repair was not complete. the signals to the brain were not restored. that explains why he still wobbles from side to side when he walks. more than 20 dogs were treated, and most saw some improvement. this research is obviously great news for jasper and dog breeds like dachshunds which are prone to spinal injuries. but the big question is could this technique one day play a role in helping to reverse paralysis in humans? scientists funded by medical research council say this proof of concept study in animals should give the green light to a trial with patients. but warn it may not work as well. in the quest to reverse paralysis in humans, cell transplants are just part of the answer. last year rob summers from the united states was fitted with electrodes in his spine which enabled him to stand. >> in case you're wondering about the potential impact of this, there are currently around 200,000 people in the u.s. living with spinal cord injury. 12,000 to 20,000 new injuries a year. >> groundbreaking. >> this could go a long, long way. >> we'll be right back,

major development in a homicide investigation and why police have only a few clues. it's tuesday, november 20th. >> announcer: from abc news, this is "world news now." welcome to "world news now," everyone. i'm paula faris on this tuesday. >> indeed. i'm rob nelson. we'll get to that major development in indiana, ten days after the fatal blast. the story seemed weird from the beginning. now to know it could have been intentionally set, unbelievable. we'll take you to the mideast as well this morning where civilians on both sides of the deadly conflict between hamas and israel spent another night in fear. we'll have the latest on the demands to end the brutal fighting there. also this half hour, teenagers obsessed with their bodies. why some will stop at nothing to get pumped up and ripped up. the warning signs and advice for parents, however, before it's too late. i mean you always -- it's good to see teenagers are really taking an investment in their bodies and working out. but some of the other things they're doing to get the bodies are worrisome. >> people go to extremes. nothing in the extreme is good. the story clearly will point that out. stay tuned for that. then later he won a long list of award at the big amas over the weekend and now justin bieber is getting more attention because of his love life and the scene that he made in public. we'll have the scoop coming up in "the skinny." >> uh-huh. but first a frightening new twist this morning in the deadly blast that leveled a neighborhood in indianapolis. >> authorities now believe the explosion that killed two people and left dozens of homes in ruin was no accident, and now they're tracking a possible lead. here's abc's pierre thomas. >> reporter: the aftermath looks like a war zone. houses ripped apart in a massive explosion, the police initially thought was a horrible accident. >> the house shook, things fell, and we ran outside. we just see the whole house -- i mean like a -- four or five houses down from us just completely engulfed in flames. >> reporter: authorities are releasing new details, suggesting the natural gas explosion that left two people dead may have been murdered. >> based upon those interviews and the results of the search warrants we can confirm tonight that there is an active homicide investigation in this matter. >> reporter: there have been reports of a white van near the home before the explosion. police have been conducting interviews and searching homes in connection with the tragedy. >> specifically if anyone has any information about a white van seen in the subdivision on the day of the explosion and about the occupants of the van, we urge you to contacted crime stoppers. crime stoppers is offering a $1,000 reward for information leading to an arrest in this case. special agent in charge, robin schumacher, of atf, authorized a reward up to $10,000. >> reporter: 34-year-old john longworth and his wife jennifer were killed in the explosion that leveled two homes and severely damaged dozens more. >> today i went to the funeral mass, and during that mass i was having trouble within myself coming to a sense of peace and reconciliation. i could not even imagine what the families are going through if i could not do it. >> reporter: it's unclear what the motive may have been for such a horrific crime, and police would not say if they have identified specific suspects. neighbors left behind are stunned wondering who could do such a thing and worried it might happen again. pierre thomas, abc news, washington. what a chilling turn in that case. an important legal note to pass on. under indiana law, a murder charge could be filed in connection with the death -- at least two deaths in this case, if they find the explosion was the result of arson here. so if they do find the person responsible for this, they could be charged with murder. >> and the cruel irony of the timing of this, those revelations just came to light just hours after the cupped was laid to rest. and just to let you know who they were, he was an electronics expert and a nature lover who liked to garden. she was a teacher who knitted gifts for her students. hard to imagine anyone would target such a loving and likable couple. >> heartbreaking story on a lot of levels. well, we turn overseas now where the fighting between israel and the palestinians enters its seventh day. nearly 100 rockets were fired yesterday from gaza into israel. the palestinian death toll from israeli attacks has reached 111, including 56 civilians. now, three israeli civilians have been kill and dozens wounded since last week, and nerves, they are on edge. >> over 500 rockets, mortars, and missiles have been fired at the israeli civilian population. the minister of defense instructed the idf to be ready to be prepared for all options. >> israel says since the beginning of its military operation hackers have launched more than 60 million attempts to disrupt various government websites but were only successful in knocking out one site for a brief period. meanwhile intense negotiations are under way at the u.n. and in egypt to finally reach a truce here. we asked abc's christiane amanpour in jerusalem, where diplomatic efforts now stands. >> reporter: the gang of nine are meeting. that is the prime minister and senior advisers and cabinet to try to figure out how to respond to a proposal put forward by egypt. so the effort is really under way to have a diplomatic solution. whether it works or not we are waiting to see. all the american efforts are going through egypt when it comes to hamas. they're taking the lead. from what we understand, egypt wants to have a cease-fire, then a bigger negotiation about lifting the siege of gaza. hamas wants that all to be part of one agreement. and israel wants to see a stop of hostilities, no more rockets into israel, and doesn't want to link that to a cease-fire. so those are the parameters. how they get close together to make a success of this is really what's under way right now. >> thank you, christiane amanpour, reporting from jerusalem. the "l.a. times" did a great story on this, kind of summed up the heart of the conflict here and said any sort of agreement much overcome huge obstacles. israel views hamas as a terrorist organization. and the islamist militant group refuses to recognize israel's right to exist. that's the fundamental barrier between the two, above and beyond the daily fighting and violence there. >> and in washington, they believe that if the rockets continue from gaza into israel that a ground invasion may be launched to stop those missiles. and if that does happen, then hamas will risk a ground invasion, that really they will completely be overdominated. >> the thing is the political chief for hamas had harsh words as recently as yesterday for prime minister netanyahu, calling him a child killer and a murderer. we see the civilian death toll climb up. so talk of a truce, but also harsh words flying in the middle of all that talk of peace. so, again, we will follow that throughout the day and coming days to see if there's a resolution. moving on this morning, most major asian stock markets traded higher in reaction to a powerful stock surge on wall street. traders were buying yesterday amid talk from washington that a deal to avoid that so-called fiscal cliff could be reached by the obama administration and the congressional republicans. the dow had its best day since early september. it climbed 207 points. to use a phrase from monte python, hostess is not dead yet. it hopes that a last-minute deal could come as it's going out of business. hostess, the second largest union will open court ordered mediation today. if a deal with the maker of twinkies and tasty treats can't be cut, a liquidation hearing will resume tomorrow. grab your ding dongs, keep your fingers crossed, king dons, ding dongs. >> i still don't know what the king dons

olympic mountains. blizzard warnings in the northern rockies. 20 degrees warmer than normal from denver to dallas and detroit. some showers in south florida. >> you're going to see 70s from dallas to miami, 50s in the northwest and midwest, 60s in the rockees. and we should say off the bat we picked up the next story from a website called offbeatchina.com. you're quickly going to realize why. >> the website says it all. check out the hottest model in china. a very unlikely fashion icon to say the east. here the off beat part that actually a 72-year-old grandfather. his granddaughter is one of the owners of a hot line of fashion for teenage girls. >> no way. they say grandpa is everything they want in a model, particularly his svelte look and thin yet lovely legs. offbeatchina there. how this all came about. he was helping unpack inventory boxes trying to display the different ways you could mix and match the clothes. then they started taping, and voila. >> i imagine grandma may have
