official. and a report about the alds rape at the university of virginia ready for the summits of americas in panama. we look at the issues to be raised and what the u.s. hopes to accomplish tonight a look at a battle inside the refugee camp in the outskirts of syria's capital. this appears to show i.s.i.l. fighters inside the yarmouk camp where the shelling began. i.s.i.l. has taken control over most of the area. hundreds of civilians managed to nee. many are trapped in conditions the u.n. calls complete depravation. the yarmouk camp is 10 miles from damascus. and has seen deadly fighting since the start of the war. yarmouk was set up in 1957 to mouse palestinian refugees. 150,000 people live there. many fled since the conflict in syria began four years ago. it's home to roughly 18,000 palestinians and syrians. because of the fighting yarmouk has been cut off from essentials like food water and medicine. many are starving. stefanie dekker has more. >> the yarmouk refugee camp has been besieged for more than two years. people starving no running water or electricity. i.s.i.l. has taken control of most of this amp. -- this camp. some civilians coped to other areas. -- escaped to other areas. >> translation: civilians are afraid and most have fled. they are afraid of being attacked by i.s.i.l. some have reconciled. aid is coming to the areas. the u.s. got aid to the palestinians thousands are trapped by the fighting and there is the fear of government attacks, trying to push i.s.i.l. out. the syrian observatory for human rights says that the government is targetting i.s.i.l. positions with barrel bombs. this camp is less than 10km from the center of damascus. others join in the fight against i.s.i.l., but have not managed to gain much ground. there's statements that al nusra is helping i.s.i.l. they say they are neutral. there'd been a deal in the works between groups and the government. a deal was about to be signed where the palestinian factions would lay down their arms and in return the government would end the siege. he says al nusra doesn't want that and fighters allow i.s.i.l. to enter the camp. whatever the politics what was a desperate situation, it has gotten worse. >> the united nations called for a humanitarian corridor to allow civilians to leave. the people are dependent on aid. none has been delivered. hospitals and clinics are no longer functioning properly. with i.s.i.l. in control of the camp negotiating forms of humanitarian relief seems further away than ever turning south to the arabian peninsula. houthi rebels are advancing on government forces in aden. a senior houthi leader says they are ready for peace talks, but only if the saudi-led bombing campaign stops. there has been a break through to bring supplies to people. the saudi-led coalition says it will allow a window of time. 9 were killed in fighting in aden and 61 others injured. we have more much- >> reporter: most of the fighting on sunday took part in the south of aden. heavy fighting was reported as houthi rebels and fighters loyal to the deposed president ali abdullah saleh managed to ipp fill trait the area. -- infiltrate the area. they were met with strong resistance from fighters loyal to abd-rabbu mansour hadi. near in other distributes there were battles, aden is the center of the war. parts of the city have been without water or electricity for two days, and there are fears of a growing humanitarian crisis. >> we have random shelling by houthis on home civilians, and i feel the humanitarian crisis in aden is worse by the hour. we punish there was cooperations between houthis so we can pass medical supplies. despite the air raids, the houthis and allies are fighting back. they are well armed. the port of aden on their list of targets. the coalition airdropped weapons and equipment for fighters battling the houthis in aden. it has not been enough. coalition jets carried out more raids, lighting up the sky off the capital. it ipp cloud this military base and other locations controlled by the rebels and fighters loyal to the former president. this village near the capital city sanaa was hit. >> four rockets came down on the village. they were targetting a camp. is this the camp. these are sleeping muslims. >> overnight houthi rebels ransacked the homes of politicians. the political front for the muslim brotherhood and the houthi rivals. >> these illegal procedures are a result of rejection towards what is done by the houthis, and their supporters against rebels in the southern governed rate particularly that of aden. we reject the procedures. >> reporter: there is another potential front. rival fighters are showing off, protecting a vans in the east. they reportedly gained control of an area taken over by fighters allied to former president, and known to be former members of al qaeda. yemen is on the verge of collapse. the fighting can worsen humanitarian conditions of an impoverished nation. four nations are working to evacuate citizens from yemen. the french army offered safe passage. the civilians were transported to the east african nation across the gulf of aden. china, egypt, sudan, canada germany have been working to get the citizens out of harm's way. kenyan authorities say one of the slain gunmen in the attack is the sun of a government official. the attacker was identified as a former law student at the university of nairobi, who disappeared in 201 apparently joining al-shabab in somali. the armed group claimed responsibility for the massacre, which killed 150 christians family members of the victims began the heart-wrenching task of identifying the bodies of loved ones. >> relatives of the university students came to the mortuary in nairobi expecting the worse. following the attack by al-shabab, the loved ones were not among those rescued or injured in the hospitals. they queue to see if their sons daughters, brothers and sisters are among the bodies. one family went to tell the story, so we went in there with them. she was studying to become a teacher. her mother found the body. the agony of identifying her own child was made worse by the violence of her death. >> those children died a painful death. i can't identify my own child from her face. she has wounds on her skin. i identified her with a folded toe and the scar on her thigh. >> reporter: a red cross list of survivors is checked and rechecked before relatives are faced with a task of searching among the dead. it may take days for the bodies to be identified. the people coming out are extremely distressed. the process of identifying the bodies is traumatic. what i saw when i was in there was the worst thing i have seen. there were dozens of bodies lined up on the floor. the morticians did their best to make them look decent and identifiable. that was clearly difficult because their injuries were severe. the smell in there is overpowering. out here the smell of the bodies and the chemicals used to treat them. >> prayers and song are the only comforts. religion is important to many. the minister of health came to visit. many are questioning the government for failing to protect the attack. >> he said it's doing its best. >> all government installations, whether it's hospitals or universities or other government installations, it's been of course strengthened. but we make sure going forward we don't have such incidents. >> reporter: for people here it's too late. the their ordeal is beginning. they have to wait for post mortems before they can collect bodies and arrange funerals. >> al-shabab's worst attack in kenya left hundreds from dozens of families struggling and in pain officials called for increased security ni in churches throughout kenya. at a mass in the town of garissa where the attack took place six armed guards stood at a church entrance as dozens celebrated. christians sang the kenyan national anthem in defines of the attack. the pope called attention to the plight of christians in africa targeted by violence because of their religion. as thousands gathered at st. peter's square pope francis led a pair. he called for the attacks to end in libya, egypt. syria, south sudan, nigeria, and the democratic republic of congo. hundreds of christians gathered in jerusalem at the church of the holy seper kerr a site where jesus was crucified. in the west bank worshippers honoured bethlehem. it honours holy week commemorating the resurrection of jesus. >> together we find out what led to a "rolling stones" article about an alleged rate at the university of virmia. courtney kealy joins us. the report was released moments ago. >> yes, it was. the columbian school of journalism was asked to investigate the editorial process used to public the article "rape on campus", in november 2014. a young woman, identified as jacky, told a harrowing tale of gang rape at the frat house. much was debunked by news outletsment moments ago the grad school released a report. saying three failures of recording stand out. involving basic, routine practice not special investigative effort. the report says in hindsight the most question shall decision "rolling stone" made was to accept that: the report doesn't accuse of reporter of slander, saying: regardless about the facts around the story, the main idea about raising awareness of campus rape was lost in the uproar. >> reporter: the allegations in "rolling stones" magazine sent shock waves. a young woman, jackie gave a detail of a manning rape at a fraternity house in the university of virginia in the fall of 2012. jacky's narrative was wove ep throughout the article to back up the points that the university fails to protect female students. >> i think they know to a long time a great harm was done to this student and many. they are taking action now because there has been a great harm done to the reputation and it's been paramount for then. >> reporter: sabrina spoke to al jazeera after the article was published and said the school why is un cooperative and wouldn't allow access to key administrators. protests occurred on campus. after the article, official of u.v.a. vowed to crack down on the assault and asked the charlottesville police to investigate. several others came back with similar stories, including this woman raped 20 years ago. >> i feel nothing changed since 1984. when ahead jacky's story i'm in that room. it is the same place, the same smell, the same feelings of being groped. . >> reporter: within days "the washington post" found glaring discrepancies. close friends found a different story. while she met drew it turns out no one worked at the university pool. "rolling stones" admitted that it did not independently verify jacky's account. in december it published an apology, calling the magazine's trust inform jacky misplaced. laura dunn a rape survivor and lawyer, was quoted in the article. >> to hear that they were digging into the issue, and packing it on a campus i was excited. i thought the coverage would be important for others. >> they worry the important point, a conversation about sexual assault will get lost in the fall out. >> doesn't mean it didn't happen or the story doesn't have an important role. >> e va imposed new rules to make parties safer. >> there's a lot of discussion about journal. >> behind the article. it's irrelevant to what we are trying to do. we think that the article pointed out changes that need to be made. >> in late march the charlottesville police chief announced investigators found no evidence to support the allegations made by jacky in the article. he added that it doesn't mean something terrible didn't happen to jacky. >> thomas the columbian university school of journalism will hold a press conference. the two deans that wrote the report will be asking questions. we'll hear more. >> do we know if there'll be a public apology? >> "rolling stones" detracted the article and apologised. we have to wait to see if the writer apologises. >> we'll hear the details about the report. this will be the stuff of journalism schools, the media critic said this will be the most egregious error, and named one of the worst smacks. it's infamous. thank you. coming up on al jazeera, israel's prime minister speaking out about the iran nuclear deal saying it's a bad and dangerous deal the boston marathon bombing trial moves closer to an end, a preview of the closing statements. plus leaders of north, central and south america gather in panama for the summit of the americas. for more of the major topics we ipp vied you to join us for "the week ahead", coming up in about 15 minutes. >> now

i'm trying to kill a bad deal. >> the israeli president is urging merge to look deeply into the agreements. >> reporter: a few days after the announce. of an agreement to limit iran's nuclear capabilities, israeli prime minister binyamin netanyahu went on political talk shows in america to argue it's a bad deal not only for israel but the world. >> it leaves the pre-eminent terror state with a vast nuclear infrastructure. not one centrifuge is destroyed. thousands will be left. not a single facilities nuclear, under ground is being shut down. >> president obama's key nuclear scientist ernest moniz hit back at critics. >> we'll have eyes on through the international atomic energy agency and the supply chain of uranium, going to the mines, and the mills, surveillance of centrifuge production and facilities themselves. if they fail to meet any of these requirements we are going to know through our access and transparency. that will lead to us and the international community, the p5+1 taking appropriate action. >> reporter: a lot of work needs to be done issues like when and how sanctions will be lifted and how inspections will work. they are a couple of the overall details of the agreement have yet to be made public or be worked out. for the obama administration it comes down to selling the deal to congress. lawmakers want to review the deal. president obama will veto the deal. iran will know that a future president will have other ideas, and that could threaten the negotiation process. demrosing statements are set -- closing statements are set for storm in the trial of boston marathon bomber dzhokhar tsarnaev. the defense rested hours after it began making its case. john terrett joins us what have we learnt so far in the trial. >> we have learnt a lot in the last couple of weeks, since the defense rested their case last tuesday. they are pinning hopes on convincing the jury that dzhokhar tsarnaev was a confused kid dominated by his brother. the prosecution asked the judge to remind the jurors that dzhokhar tsarnaev didn't have to know all the plot to be guilty. >> reporter: lawyers for dzhokhar tsarnaev rested their case a day after calling their first witness. the suggestion dzhokhar tsarnaev participated in the boston attacks, but he was a troubled 19-year-old living under the spell of his radicalized brother. >> the defense showing older brother influence. and showing the motive had more to do with that than terrorism. >> from the beginning the defense said the strategy was not to win an acquittal but save the client from the death penalty, a move highlighted by calling four witnesses over two days, witnesses that tied older brother tamerlan to the crime. it was testified that tamerlan's fingerprints, not the brother was on the remote control to trigger the bombs. 92 witness were called over 15 days of testimony, including experts providing a mountain of evidence from the crime scene before resting on monday. >> the prosecution tried to bring the jurors to the scene of this horrible horrible crime to show the devastation that it caused to loved ones, to folks who lost their limbs. so that the jurors, when they decide about punishment will have all of that in mind when they make those decisions. >> reporter: trial watchers noted dzhokhar tsarnaev showed no emotion. one of those is heather, the second bomb taking part of her leg off. >> i was surprised at his demeanour in court. i don't understand how a person like that thinks. >> reporter: now the trial of the century in boston is moving to a conclusion. >> it's mentally draining trying to get here, being here, seeing the horrific pictures and the testimony of the poor people that passed away that day. >> prosecutors and dzhokhar tsarnaev's lawyers will give closing arguments and the jury get the case later in the day. it's not about guilt but influence, what will happen tomorrow? >> we'll have the closing arguments. prosecution, defense, and the jury will be dismissed after being instructed by the judge, they'll go to the jury room and the foreman will take a vote and a lot think they'll vote in favour of him being guilty and they'll be back into the courtroom quickly. there's three outcomes. the jury could come up with not guilty unlikely. they could come up with guilty but not the charges pertaining to the death penalty, or guilty of all charges 1-17 that are pertinent to the death penalty. we'll have to wait and see if they vote in favour or hand back a decision based on him being guilty. there'll be a second phase of the trial in front of the same jury. they'll hear different arguments about whether dzhokhar tsarnaev should be put to death or given life. >> we'll follow this one closely. >> coming up on al jazeera. in the week ahead the summer in americas in panama city. we discuss what is on the zaepda. stay with us. we discuss what is on the agenda. stay with us. . stay with us. i can't welcome back to al jazeera america. here are the top stories - yil consider fighters took control of a refugee camp. they have a presence 10 miles from bashar al-assad's presidential palace. hundreds fled the camp. those there are caught in the middle of fighting desperate for food and water. in yemen houthi rebels are advancing on forces in the port city of aden. nine from killed. 61 injured. the saudi-led coalition will allow a window of time for humanitarian aid to be delivered. >> columbian university released a report on the journal. >> behind a "rolling stones" article about a rape at the university of virginia the article was debunked by other news outlets. columbia's report says the mistake was accepting the reporter didn't contact witnesses with the cueser the night she was allegedly raped. it's sunday night if time for week. the summit of americas will be held in panama city. the event has beenedly every three years since 1994 it's a chance for leaders from the north, south and central america to come together to discuss issues. we have correspondents in argentina and mexico. we begin with this report on cuba from david ariosto cuban president raul castro is heading to a summit. all eyes will be on whether he and president obama will shake hands. castro's government is focussing on two things - raising the flags - cuba and the united states want the official embassies to re-open in havana and washington. the second is a u.s. list of state sponsors of terrorism. cuba made it clear it wants off. there's indications that the u.s. is willing to play ball. after the big its are resolved. we can start talking about what normalized relations between the countries mean. cuba's old ally is in the mix, and it could spoil the kooum buy ya moment. sanctions were snapped and the president is likely to be a thorn in the side of president obama, as he plays nice with leaders. expect all of this to play out at the summit of the americas. >> this is cristina fernandez de kirchner of argentina has been friends with the cuban government. they'll be happy to meet up with raul castro in panama at the summit. what most concerns argentina is what they see as a diplomatic push to get britain to the negotiating table over the future of what they call the maldeanas islands, the britains call the falkland islands. relations tense between argentina and britain. cristina fernandez de kirchner will be looking for a latin american solidarity. she didn't get what they wanted at the last summit of americas in 2012. she'll push harder here in - in pan ma. where the rest of the latin america is concerned, we'll have to see. them express solidarity. whether it amounts to much in the long term is unlikely. >> i'm john holman in mexico city. and the president peno nieto will be heading to the summit of the americas keen to talk about reforms that he and his government enacted. including education, energy and tying in with key talks points selected for the summit. he'll be looking to show mexico as an example for the rest of the region. what he'll be less keen talking about is a difficult last knew months for him and his government. chief among the scandal, the appearance of 43 students and local police and government were involved in the comparisons. in a way this will be a way to escape those issues and show himself and mexico in a positive light on an international stage. he'll meet outside of the summit with the president of brazil panama and the united states president obama in a meeting where they'll talk about trade, economic and social develop. in general for mexico they'll hope for a smooth summit in which they can show the country as a region's leader and a country moving forward. what can we expect in the week ahead. joining us for a closer look is david ariosto. he's reported throughout latin america and will attend the summit next week. it will be an historic event. what is next after cuba's invited. >> this will be a highly and choreographed moment. the expectation is to raise the flags in washington and havana. it's increasingly improbable. it seems to be a bureaucratic issue. cuba wants to get off the state-sponsored terrorism list something they've been on for decades, it's the last shoe to drop so to speak, to allow the normalization of relations. cuba needs american cash. that's what we are talking here. there'll be a summit tied to the summit of americas thursday and friday. representatives from koch boeing. cuba needs the money. in the wake of falling oil prices they are cash strapped. they need american tourism or some microfinance that president obama talked about, and the summit promises to be a great opportunity. >> we are in the early stages. there are major sticking points we have to deal with. the white house says there'll be an interaction. do we expect to sit down or a photo opportunity between the two presidents? >> that's a great question. if i had the answer we'd make more money than we do now. the expectation is there'll be the handshake. will there be something more than that? president obama shook the hand of president castro. and he has spoken to him on the phone. it's not the first interaction between the leaders. this is an opportunity to get at the tops of government to drill down and find the nitty-gritty of details, and what the smaller or lesser officials will iron out. they have met three times already. who knows how many times they met prior to this. this will be an historic moment. >> the focus will be on human rights how does president barack obama address human rights and not stip on the toes of cuba. marco rubio announced a big announcement at the freedom tower in miami, where refugees in cuba came to the united states in the 1960s. he'll be playing off the - he'll choreograph the moment trying to get the handshake of president obama and raul castro. you'll have groups travelling from havana to panama city. a daughter of a dissident killed in 2012 was detained in panama over the weekend. there could be fire works. that coupled with the president, the sanctions lobbed against his government. this will be a summit worth watching. >> i want to go to mike viqueira in washington. will we see less isolation towards the u.s.? >> it's an interesting point. the united states is in a strong position. you have the argentina's facing a crisis. elections are coming up in the country. they are heavily dependent on oil. the price of oil dropped by half. hovering around $50. all the nations in latin america that are in a far more precarious position than they have been. the united states economy is doing well. they have extended the olive branch to cuba there's less excuses to deal with the diplomacy that leaders have been waiting for. >> as we mentioned in a landmark move. the u.s. will attend the summit. mike viqueira has more from washington. >> it will not be another meeting. the summit of america taking place in panama has taken over overtones. there's likely to be a face to face meeting between the american president and raul castro. the president making a surprise announcement. for years the united states blocked cuba from attending the gathering. last month the president said he wanted an american embassy to open in havana before the summit of americas. a breakthrough has not been yielded and the goal of opening an embassy will likely not be met. a poll suggests a majority of cuban americans favoured normalizing relations. also in the summit latin leaders expected to press president obama to do more to go along with emigration reform. >> and relations is also likely to be a sore point after president obama orders sanctions for human rights violations. the president arrives at panama on thursday. al jazeera's david ari oft af joining us again. the attention to center stage may play out between the president in the class. nicolas madura has the chance to steal the show. the energy sector has been tanking, they've been relying on that. they've been reliant on china's debt. that'll be interesting. they are not invited, but it's an underwritten code. so many different relations heavily indebted to china. part of the reason why the united states is negotiating a greater diplomacy. venezuela is interesting to watch. during the last summit. this was when chavez was sick. he did not attend. nicolas maduro was vice president at that point. he's coming to the summit in protest. he's bringing 10 million signatures of residents within his country, that they need to get rid of the sanctions. keep in mind they are not against all of venezuela, but it speaks to this old world type of mentality that is in play within latin america, and that will play out as the proposed kooum buyar moment between raul castro takes place. >> we'll talk more about that. you'll cover that chorus. -- for us. the americas voted cuba being invited. canada and america opposed. the president's relationship has been cold since dilma rousseff phone tapping. after china it is america's second-largest mark. the topic of china is sure to come up. beijing linked latin america and the caribbean more than half a billion. to discuss more i'd like to welcome eric faans worth. the former president joined us. great to have you with us on week ahead. >> good to see you. i know the tone of the leaders is important. what needs to happen. first of all happy easter. it's good to be with you. i think the summit is an important opportunity for the united states and cuba to show that both countries have turned over a new leaf. the question is what concrete actions come out of this particular meeting. they were most likely a handshake, some sort of interaction. we don't know what meeting, perhaps, but that - you know that's a good first step. the question is what's next. the other question is what will be the posture of the other countries at the summit. it's not just the united states and cuba it's all the country in the western hemisphere and some will be focused on the fact that they don't much like the united states whether or not there's a coming together with cuba. the example that venezuela is an issue, there's a pressing issue, and the fact of the matter is that could steel thunder in terms of positive momentum and feeling in terms of the u.s. cuba. >> you bring up a good point. what is the dialogue that needs to take place between venezuelan and the u.s.? >> well there should be a dialogue not only between venezuelan and the united states but a dialogue between venezuela and the inter-american community regarding its constant systematic and increasingly brutal violation of human rights of basic freedoms and representative democracy. unfortunately it looks like as always the latin americans will not take on venezuela on the issue, nor will the united states, because it does not seem to want to have a discussion or public debate with venezuelan get in the way. that's probably the right stands for president obama to take. but it will increase the cost for him domestically. he will not always see the republican right-wing as caving in to raul castro and also nicolas maduro. my question is that he'll try to compensate by that by meeting with the wives of the two leading venezuela gaoled opposition leaders. leopoldo lopez and another at a meeting in panama outside of the summit. that will only get nicolas maduro more ticked off, and his friends what can we expect from the presidents of columbia peru mexico. does the conflict between the u.s. and venezuela matter or will they focus on their own economy and innovation? >> i think it matters a lot. latin american's economy broadly this year is predicted to have turbulence. it's not growing rapidly like in the past. some is related to china's slowing and commodities and other factors. a summit of the americas is an opportunity for the region to come together and find ways to cooperate economically, whether on energy trade, investment or what have you. in the countries of mexico columbia and chile - they don't have. sympathy for the venezuelan regime and may feel obligated to support the team. the real interest is to support the economic relationship with the united states. the hope is that venezuela does not take over the summit. as china close, it is one state that is recovering. it's one thing to speak rhetorically in the united states it's another to develop an economic relationship and build that relationship for mutual benefit. even venezuela, a country, if you listen to the government pronouncements it sells more product, oil and petroleum to the united states. that economic relationship is strong between the u.s. and venezuela. there's stom irony. other counties of the world have to see what are the priorities and pursue that. >> ecuador's president says there's a u.s. lack of report for latin america. a few shared by some in the region, what can the u.s. do to ease the mistrust. >> look i think my friend eric will agree that obama, unlike men many of his predecessors has done just about anything anyone would ask for in terms of so-called respect for latin american nationalism and old-fashioned anti-imperialism. including cutting a deal with cuba which as your correspondent said before is looking more and more difficult. everyone expected the two embassies to open before the summit that locks unlikely and there were serious sticking points regarding that let alone normalization including human rights issues claims by americans on expropriated human properties et cetera et cetera. the main question is for people like corera and like el salvador even like cristina fernandez de kirchner in argentina. there is really nothing a president of the united states can do to give full respect to what they consider their country's national pride, other than more or throes disappear. president chavez before he died in a very extraordinary interview with john lee anderson five or six years ago i think put it best that he was sincere in his own naive way when anderson asked him "do you think there's a way to get along with the united states", he said as long as the united states is an imperialist power and does not have a socialist government know there's no way. >> i think that pretty much sums up what most of the latin american left of that nature things about relations with the u.s. >> i want to talk about the role brazil may play. there's a role in corruption issues. brazil never a gan of the summit. but on which issues does the u.s. look to brazil. >> hopefully a restraining role in venezuela. it would be helpful if someone gets to the president of venezuela and suggests it would be a bad idea to present to the president of the united states a list of 6 million, 10 million or any number of names on a petition against the united states. this is showmanship. it's a political stunt. it's not helpful, and a restraining position i think, could be helpful. brazil is the largest economy in latin america, and between the united states and brazil. there's a huge amount of work to be done in terms of cooperation on energy agriculture as the w.t.o. or other at the g20. it's an opportunity for both countries to move forward in support of democracy and open market economies. i think you noted accurately that the president of brazil faces domestic troubles there's corruption issues a slowing economy and the weather is working against brazil. it's understand going a drought, which affects the electricity production. a lot of that comes from hydro-power. there's a domestic issue that the president has to work through. what does she want to do at the summit in panama. probably she wants to go meet return to brazil. i imagine she won't take a high profile, consistent with the brazilian approach. >> you have 15 seconds, but what will make the summit a success. quickly? >> it won't be a success, the handshake is important. coping nicolas maduro quiet. having obama not taken on as an adversary by everyone is important. that's about as much as can be expected. the summits have never been that important or significant. it's not going to be a big deal. >> your final thought on the summit? >> i think that's right. it would be helpful if some of the countries say enough with this old world antagonism. let's move forward. there's a common agenda and center. let's pursue those and leave the theatre behind. appreciate our time on the week ahead. before we go other news coming up in the week ahead. tuesday - residents of ferguson, missouri wrote in elections since the death of michael brown. many are hoping the elections will bring about change. wednesday - secretary of defense dawson carty visits asia and japan and south korea, discussing security issues and china's military and the issues surrounding north korea friday - the national rifle association holds its

us with the weather. >> happy easter. normally people would complain about the rain. i don't think california is. we'll get rain it's out of the rainy season. we are going into the dry season. what is happening here is we'll look at the eastern pacific, you see the area of low pressure spin making its way down ushering in showers for california begaining as snow. it's coming down to the valley.
