Cnn newsroom starts right now. In rauk, isis has claimed responsibility for a deadly attack just north of baghdad. It happened at a cooking gas plant. You see the big explosion here there. At least five Police Officers were killed. More than a dozen others were wounded. Two suicides bombs went off at the plant. One at the entrance and another inside the actual facility. Six isis militants then tried to storm their way inside but Security Forces were able to hold them off. Following all of this, our ian lee joins us live in cairo, egypt. First of all, the fact that this happened so close to baghdad, its a big deal. What more can you tell us . Thats right, george. Were getting an update. Now were hearing that seven people have been killed and 24 wounded. What were seeing by isis now are these sleeper cells being activated around the country. As weve seen them lose territory with the advancement of iraqi Security Forces as well as the peshmerga. Weve seen an increase in the number of attacks like that. This one happening just north of baghdad. Also, last wednesday, there was a string of suicide bombings that killed more than 90 people, so this is a change really in the tactics, a shift, if you will, in the tactics that isis is using going from more conventional battlefield tactics when we see the two sides go headtohead to moving to these sleeper cells. And talking specifically about this target again that isis tried to storm their way inside a cooking gas plant, whats the significance, if any . This is really going after infrastructure and weve seen isis try to do. A mixture of infrastructure as well as hitting soft targets. This cooking gas plant, a lot of people rely on cooking gas canisters for cooking in their households, sometimes for hitting heating, so it is a significant target. It does have a real impact psychological. If they were able to be successful and destroy this plant. Fortunately, Security Forces at the plant were able to stop them before they were able to destroy the whole thing, although three gas containers, gas structures that are holding it were destroyed, were lit aflame. So these are significant attacks when they do go after the infrastructure like this, george.

On now to nigeria where boko haram was the focus of a Security Summit that was held saturday. Delegates from global and regional parties attended, including french president francoise hollande. The u. N. Security council said friday that the terror group threatened regional stability. At least 20,000 People Killed since boko haram first waged war in nigeria. Since 2009, the terror group has been labeled the most deadly in the world by the latest global terrorism index. A terror so great, governments came together with plans to Work Together and to fight back. Since the last meeting of delegates two years ago in paris to discuss the problem and find solutions, the Islamic Extremist Group has been pushed out of territory it once controlled in northeastern nigeria, instead resulting in smaller Suicide Attacks. With the worsening refugee crisis, people came together to discuss strategies and to affirm they are not letting their guard down, supported by the United States, u. K. , and france that will play a key role in the fight. Translator boko haram has been weakened but it is still capable to conduct attacks of harassment and equally deliver Suicide Attack in the middle of the civilian population. We have to support the Nigeria Armed forces and the regional countries. Help them to be more efficient. Be with them whenever its possible and prepare their staff and provide training. Western governments worry that isiss growing presence in north africa and ties with boko haram could herald attacks south. The United Kingdom has pledged to give nigeria 40 Million Pounds to fight back. The growing cooperation between daesh in the middle east and boko haram in this region is a growing threat. As daesh faces increasing pressure in its heartland in syria from the the internationalco arigs coalition, theres a real risk it increases its efforts in support of boko haram here in nigeria and across the wider region. Regional and world powers coming together to try to fight boko haram.

Ukraine is celebrating but lets talk about the lyrics. It has russia very angry. Ukraine pulled a surprising win over 2 top favorites. For most of the competition it seems like australia was going to win. This was the second year that australia was invited to compete and it won the jury vote and russia won the popular vote, but at the end, ukraine had the combined most votes. Earlier, cnn spoke with journalist william lee adams. Hes an expert on the euro vision song contest and has been covering for years. It was an incredibly slick production and so many acts were bringing their a game. It came down to three countries, australia, russia, and ukraine. It was all about the ukrainerussia narrative. Russia had been the favorite for months. Ukraine, the singer was a crimean tar tar ander great grandmother was one of the victims who lost a child on the long march out of crimea. People have said the song is very much a slight against russia because it speaks about this dark period of the past but jamala, the singer has said no, this isnt political, its personal. If you want to call it political, its down to you. Not me. Interestingly, the ukrainian, the ceo of Ukrainian Television said prior to the contest if russia won, ukraine would withdraw last year. Incredibly heated. Its a huge slight against russia for russians. People are taking it very personally. I love it that russia is singing a very sexy song about loving a woman and ukraine has got this deep historical message. Justin timer ber timberlake was there. What about the dichotomy . Russia is chose a perform er who wears pik leather pants. Its almost saying we can do camp too. Mainly our laws arent as draconian as you think. Then you have ukraine, obviously in light of the annexation of crim crimea. Their performance was much more theatrical. It was drama. She was singing for hundreds of thousands of victims and when she screamed she was screaming for them. Many ways they went live because this was filled with so much of a back story. At one point, the floor fills with yellow and blue light, the colors of the ukraine light. It sucked up behind her in a tree of renewal. Shes suggesting a Bright Future for ukraine through her dark song. Coming up, why a top official says he quit the World Football body of fifa. Plus kenya plans to shut down all of its refugee camps. Why aid agencies say that would put lives at risk. Stay with us. Look at em theyre lovin their vegetables. This is huge news its all thanks to our birds eye chefs favorites side dishes perfectly sauced or seasoned. What are you. . Shh im live tweeting. Oh, boy. Birds eye. So veggie good. In the United States, the democratic president ial frontrunner, Hillary Clinton, is launching a new attack ad against her likely opponent in november, donald trump. The boil ordinary is refugeeing refusing public calls to release his tax returns citing an audit. Heres a look at the latest ad. Maybe im going to do the tax returns when obama does his birth certificate. The state of hawaii released my official long form birth certificate. I would like to run for office, ill produce my tax returns, absolutely. Im officially running for president of the United States. Getting any closer to releasing your tax returns . Im thinking about it. I cant do it until the audit is finished. The audit is no excuse. The irs made it very clear that audit is not a bar to public release. Its entirely your choice. Its none of your business. Clinton obviously there turning her attention to the general election, but her rival, democrat Bernie Sanders, is still putting up a fight. He told a crowd in kentucky that he had every intention of winning there as well as the contests that follow. Nobody would have believed that we would receive well over 9 million votes at this point in the campaign. [ cheers and applause ] and very few people would have believed that this coming tuesday were going to win a great victory right here in kentucky. [ cheers and applause ] and by the way, i think were going to win in oregon as well. And then on june 7th, weve got california and a bunch of other states. So the delegate math for Bernie Sanders to actually beat Hillary Clinton for the nomination is incredibly tricky. His odds are just very slim these days but as our chief u. S. Correspondent john king tells us, sanders isnt quite out of it yet. Is there anybody who really six months ago, eight months ago, thought Bernie Sanders was going to be giving Hillary Clinton this kind of run for her money . I think maybe not. Except Bernie Sanders and his campaign team. The very rules that have kept him in the campaign, no winnertakeall states, that has kept Bernie Sanders in the race. Now it keeps secretary clinton with her lead. Its an uphill struggle. We have a chance to end up with a majority of the pledged delegates, and if we do that, i think you are looking at the democratic nominee for president. This is the problem. You see whats left of the map, right . Does Bernie Sanders have a mathematical chance . Yes, but is that realistic math . Theres 897 pledged delegates left. He needs to win 67 of them. He has not been winning anywhere near 67 of the delegates so far . So is it possible . Sure its possible. Thats mathematically possible. Would you place a bet on Bernie Sanders winning california with 67 of the vote . I think not. Look at that. All Bernie Sanders, every county in west virginia. Thats pretty impressive. It seems a little bit dumb to me if i might say so that last night where secretary clinton ended up with 35, 36 of the votes, she is going to get six out of seven super delegates in the end, shes still ahead, even if he wins everything left on the board by ten points shes still ahead in pledged delegates. A, the Clinton Campaign says this isnt going to happen. B, if it happens, unless they panic, Hillary Clinton still has in her back pocket, the secret weapon. Senator sanders could run the board, some of these people could defect. The math is not impossible but its pretty hard. The man credited with leading reforms in fifa has left in protest. He opposes a new move that gives fifa more control over committees like his own. Cnn explains. If the new president of footballs governing body thought his first Fifa Congress would be passed off without incident, he would be in a rude awakening. He resigned from his post of Compliance Committee. He quit after a surprise vote was taken on friday in mexico city, despite the fact that he had been one of the most important figeds in fifas reform process, the vote mean he and other corruption watch dogs could be sacked by the new fifa council. With this decision, it will be henceforth for the council to impede investigations against single members at any time by dismissing the responsible Committee Members or by keeping them akey he is sent of threat of dismissal. I am couldnt consternated about this decision because it under mines a central pillar of the Good Governance of fifa. They regret that has misinterpreted the purpose of the decision of the Fifa Congress. Now, friday, he veeled it was revealed, senegals first female secretarygeneral was appointed.
