country this year. this marks a 56% increase over 2015. five officers were killed in the ambush attack in dallas. three more were killed in a similar attack in baton rouge, louisiana just ten days later. in total, 21 law enforcement officers were killed in ambush-style attacks across the country. frederick frazier is the head of the dallas police association and says there are simple solutions. >> you have to have more ficers on the street. that's the easiest answer because an officer needs a partner. he needs somebody to watch his side, watch his back. >> reporter: for heidi and her two girls the grief has been unbearable. back in july 10-year-old caroke down when she told us about the last time she saw her dad put on his uniform. >> he was leaving to go to work, and i was leaving to go to a movie. and he said to me, "what if this is the last time you ever kiss me or hug me?" >> reporter: did he always say that? >> no. that was probably the first time he ever said that. >> reporter: was this kiss any different? >> yes, it was. >> reporter: how? >> it just felt different to me. i felt something bad was going to happen. >> reporter: texas and california had the most officer fatalities this year. reena, the deadliest calls for officers to answer are domestic disturbances. >> omar villafranca, thank you. in syria a new cease-fire has taken effect. earlier truces have not held for long. this one was brokered by russia and turkey, who are on different sides in the syrian civil war, which is nearly six years old. holly williams joins us from istanbul. holly, what do we know? >> reporter: well, reena, the syrian regime has apparently agreed to this deal, along with one of the main syrian opposition alliances. and the idea is that if it holds this could lead to peace talks in january. but there are dozens of syrian opposition or rebel groups, and we've spoken to some groups this evening who say that they did not agree to this cease-fire. remember also that this cease-fire deal only includes the syrian regime and some syrian opposition groups. this deal does not include isis or a powerful kurdish group. so while this could be a turning point, it certainly isn't an end to the syrian civil war. >> how is the u.s. reacting to this deal, holly? >> reporter: well, reena, the u.s. has called this a positive development, but this deal has effectively sidelined america in syria. russia's lethal air campaign in syria has managed to prop up the syrian regime, and it's helped moscow look like a truly global player, really for the first time since the end of the cold war. now perhaps this will allow russia's president, vladimir putin, to portray himself as a peacemaker. and russia has brokered this cease-fire deal not with washington but with turkey, an american nato ally that is growing ever closer to moscow. >> holly williams in istanbul. thank you, holly. today tributes to debbie reynolds filled social media. the actress died yesterday at 84. there were drawings, many depicting reynolds with her daughter carrie fisher, who died one day earlier. some showed reynolds in the rain gear that she wore in "singin' in the rain." and fisher shown as "star wars'" princess leia. last night fans raised light sabers in honor of fisher at impromptu vigils all over the country. some dressed as "star wars" character. reynolds' son todd fisher said the actress went to be with carrie. well, coming up next, can you really die of a broken heart? dr. jon lapook examines that. and later, we're on the hunt for thieves stealing something more valuable than gold. hey, searching for a great used yeah! you got it. just say show me millions of used cars for sale at the all new carfax.com. i don't want one that's had a big wreck just say, show me cars with no accidents reported pretty cool i like it that's the power of carfax® find the cars you want, avoid the ones you don't plus you get a free carfax® report with every listing start your used car search at carfax.com there is no official word on what caused debbie reynolds' death, but many believe it was no coincidence that she died just one day after the death of her daughter, carrie fisher. medical experts say broken heart syndrome is real. more now from dr. jon lapook. >> reporter: it's unclear what led to debbie reynolds' death just one day after her daughter's, but emotionally stressful events like the death of a spouse or child can trigger a sudden surge in stress hormones that are felt to stun the heart and prevent it from pumping properly or cause an artery supplying the heart to go into spasm. >> this entire part of the heart is not moving at all. >> reporter: cardiologist dr. harmony reynolds of nyu langone medical center has studied this underrecognized condition which occurs mainly in older women, many of whom have no obvious preexisting heart disease. >> this is a heart attack syndrome that unlike typical heart attack occurs with the arteries completely open. and the area of the heart that's affected is quite large, but if people survive the event it all goes away. >> reporter: symptoms can resemble a heart attack, including chest pain and shortness of breath, but may be subtle, causing women to delay seeking help. >> we don't necessarily understand why an emotional connection exists, but we know that the brain and the heart are closely connected. you can die of heartbreak. but exactly how that happens and exactly why, we don't know. >> reporter: most people fully recover, but death can occur from problems like heart failure or an irregular heartbeat. in addition, a blood clot in the heart can travel to the brain, causing a stroke. >> any idea how common this is? >> it's probably relatively uncommon but nobody knows exactly how common it is because it's probably been flying under the radar for years. but now doctors are getting increasingly better at recognizing it. in 2012 about 6,200 cases were diagnosed in the united states. that represents a 20-fold increase from just six years before that. >> incredible the impact of stress hormones on the body. thank you, dr. jon lapook. well, when we come back, a view from the top of the world's highest bridge. (achoo!) did you know you can pick up cold & flu viruses from things in your home for up to 48 hours? it's like having a sick family member that you didn't even know was there. and we all know what happens when one family member gets sick. but lysol spray and lysol wipes kill 99.9% of germs including 8 common cold & flu viruses to help protect your home this cold and flu season. check sunday's paper to save up to $4 on lysol and buy any 5 lysol products for 100 bonus box tops. thope to see you again soon.. whoa, whoa, i got this. just gotta get the check. almost there. i can't reach it. if you have alligator arms, you avoid picking up the check. what? it's what you do. i got this. thanks, dennis! if you want to save fifteen percent or more on car insurance, you switch to geico. growwwlph. it's what you do. oh that is good crispy duck. mthat stuff only lasts a few hours. or, take mucinex. one pill fights congestion for 12 hours. guess i won't be seeing you for a while. why take medicines that only last 4 hours, when just one mucinex lasts 12 hours? let's end this. a medical study out today on the dangers of sitting made us stand up and take notice. researchers in dallas found that men who spend most or all of their day sitting were more than twice as likely to be obese as those who stayed mostly on their feet. to reduce the risk of obesity the study's authors say get up and move around. well, a walk across the new bridge in china could send your heart racing because it's the world's highest and it opened today. it stands more than 1,800 feet above the valley below. that's more than a third of a mile. the bridge cuts the drive time between two southwest chinese cities from four hours to just one. nasa's mars rover "curiosity" is giving us a look at something you might not expect to see on the red planet -- purple rocks. the plum-colored boulders were captured in a series of images received last month near the martian mountain known as mount sharp. nasa says the color comes from a type of iron oxide in the rocks. well, coming up, we're on the chase for crooks stealing hot wheels of cheese. ,,,,,,,,,,, finally tonight, thieves are always after the cheddar. except in italy, where they're stealing a close cousin. here's seth doane. >> reporter: 9:30 p.m., eight officers keep watch from a convoy of three police cars. >> these patrols happen every night? >> every night, yeah. >> reporter: in 30 years on the force alessandro vaccari has never seen a wave of robberies like this. police blame organized crime. no surprise there. but the target? this cheese can be quite valuable. >> yeah. >> reporter: yes, cheese. these are the streets of reggio emilia, italy, home to parmesan. "there have been so many thefts," vaccari explained. "cheese is a bit like gold here. the price is so high." exhibit a, a single wheel of cheese can sell for over $500. the staple of spaghetti dinners everywhere is the economic backbone of these small italian towns. parmesan is so valuable that it is used as collateral for loans. believe it or not, this is a bank. it's a vault filled with more than $120 million worth of cheese. to be certified parmigiano reggiano it must age for at least a year. so that means cheese, a whole lot of it, is stacked up in warehouses on small, rural unprotected farms. lorenzo pinetti showed us how thieves made off with $100,000 of his cheese in minutes. they'd make an assembly line and steal this piece and then this piece. italy's parmesan consortium figures about $7 million worth has been stolen in the last two years. there's a robust black market. so stepped-up patrols and new security systems are now in place. "but surely this will not be the last time thieves come to visit us," pinnetti said. small independent farmers are what makes this cheese so good and such a delicious target. seth doane, cbs news, reggio emilia, italy. that's the overnight news for this friday. for some of you the news continues. for others check back with us a little later for the morning news and "cbs this morning." from the broadcast center in new york city, i'm reena ninan. ♪ >> announcer: this is the "cbs overnight news." welcome to the "overnight news." i'm tony do kooup'll. as he promised, president obama unveiled a boatload of sanctions against russia for its efforts to influence the recent presidential election. nearly three dozen russian diplomats have been given three days to get out of the country. and that is just the start of it. chip reid reports. >> russia was engaging in malicious cyber activity intended to interfere with our election. >> reporter: and for that white house spokesman eric schultz says russia must pay a price. u.s. intelligence agencies say the russians were engaged in an effort to harm hillary clinton's campaign, thereby helping the campaign of president-elect donald trump. the administration's retaliatory actions mean the 35 government officials from the russian embassy in d.c. and the russian consulate in san francisco have to leave the country within 72 hours. schultz says they cannot hide. >> well, all their credentials will be revoked. so they won't be able to -- they'll have no protections here. they'll have no diplomatic immunity here. they will be persona non grata. so they will have to leave the country. >> reporter: in addition, two russian compounds believed to have been involved, one in new york and one on the eastern shore of maryland, will be closed. further, two russian intelligence agencies are being identified and sanctioned for their role in the hacking, along with three companies and four individuals who allegedly assisted. and two russians have been identified as cyber criminals. the administration says one of the men has stolen more than $100 million from u.s. businesses. the white house says additional covert actions against the russians will not be announced because they are highly classified. on capitol hill members of both parties have come out in support of the president's actions. republican speaker of the house paul ryan called them overdue, and republican senators john mccain and lindsey graham say they "intend to lead the effort in the new congress to impose stronger sanctions on russia." a russian dpsh spoekdsman for russian president vladimir putin says there will be "appropriate retaliation." as for president-elect trump, he released a statement saying, "it's time for our country to move on to bigger and better things." but he added that he will meet with leaders of the intelligence community next week to be updated on the facts of this situation. president-elect donald trump has dismissed the hacking charges against russia, calling them ridiculous. mr. trump's aides want u.s. intelligence agencies to prove that moscow was behind the hacking and how it was done. jeff pegues has a look at some of the evidence that has russian fingerprints all over it. >> reporter: u.s. intelligence services don't often release the details of their analysis, but today they did as part of an ongoing effort to pull back the curtain on what u.s. officials believe is malicious russian cyberactivity codenamed grizzly st steppe. investigators believe the initial cyberattack of democratic party officials began in the summer of 2015 when the first hacking unit dupd apt29 sent out a barrage of e-mails containing a malicious link to over 1,000 recipients including multiple u.s. government victims. once someone clicked on the link, the hackers were in the system. according to the document, the hackers successfully compromised the u.s. political party and stole e-mail from several accounts. about a year later in the spring of 2016 another hacking unit called apt28 also targeted democratic party officials and once again deployed malicious e-mails that tricked recipients into changing their passwords. according to u.s. intelligence officials, that hack likely gave russian operatives access to the information of senior democratic party officials, which was then leaked to the press and publicly disclosed. russia has denied the all gaigss, but a u.s. official says, "i would never expect russia to come out with their hands up and acknowledge what they did." while the public largely became aware of the cyberattacks during the democratic national convention, u.s. officials believe that for about a decade russian intelligence services have been conducting cyber espionage on a wide range of targets here in the u.s. u.s. officials say that they have no reason to believe the russian cyberattacks will stop. reena, the other problem is it is likely the russian hacking units hit targets that have yet to show up on u.s. investigators' radar. funeral arrangements are still being made for singer and actress debbie reynolds who suffered a stroke just days after

the people who went to work and to church and raised their families here inspired many of his plays. >> it's a pittsburgh story, and i wanted it to be in pittsburgh. the stories i get from people, all of that helps to feed the film. >> reporter: washington turned this vacant hill district house into the maxon family home. familiar to many of us who grew up in a black working-class neighborhood at

clear standard so that our consumers have a clear understanding of what they're purchasing and there's no confusion. >> reporter: 32 congressmen from dairy-producing states agree, penning this letter urging the fda to enforce its existing definition of milk, which states, "it is obtained by the complete milking of one or more cows." but how much confusion is there between cow milk and its substitutes? >> i don't think they're the same as milk, and i think that confuses people. >> i think it should continue to be called milk. it's used like milk. >> worldwide, this is the same terminology that has been used for years. >> reporter: for nancy chapman of the soy foods association the hope is the fda widens its definition. >> when you drink soy milk, it is equal in terms of its ability to support growth and development as is a dairy cow's milk. >> reporter: chris galen works for the milk producers federation. would you be all right with a looser definition? >> i've never milked a soy bean. i don't suppose if you cracked one open you'd find much milk or any liquid there. all we want is for the government to do its job and to enforce the regulations on the books that says you don't got mill fk it comes fr milk if it comes from a nut or a seed. >> reporter: what's interesting is the fda has historically kept out of the debate over who gets to use the term "milk." but this time it says it will respond directly to the congressmen who wrote to them. we also reached out to the almond industry for comment and they tell us their product is fortified with vitamins and calcium and that ultimately it's up to the consumer to decide. the "cbs overnight news" will be right back. school science fairs can be a traumatic time for students. the kids don't know what to
