For its part, russia denied its warplanes carried out the hospital bombing in aleppo. Instead, in washington, a state Department Spokesman said all signs point to the syrian military. The indications that we have now, and again, this just happened, are that these were these strikes were conducted by the regime. Sreenivasan and in a statement, secretary of state john kerry insisted russia use its influence on president Bashar Alassad to stop the attacks. The main Syrian Opposition group joined in, from turkey, blaming moscow and damascus for the resumption of fighting.

He urged the United States and russia to salvage the truce and bring the warring parties back to the table. The Russian Federation and the u.

Lifeline to hundreds of thousands, if not millions of people that have had hopes that things would really get better now that lifeline may be broken. Sreenivasan adding to the warning, the International Red cross reported stocks of food and medicine in aleppo will run out soon, and the resurgence of fighting makes it impossible to bring in more. Well hear from Doctors Without Borders after the news summary. Woodruff in the days other news, theres word that 16 u. S. Military personnel, including a general, have been disciplined over the mistaken bombing of a hospital in afghanistan. The facility in the city of kunduz was also run by Doctors Without Borders.

And, chinese president xi jinping said his country will not permit war or chaos on the korean peninsula. Sreenivasan president xis government is moving to crack down on foreign nongovernmental organizations with operations inside china. A law adopted today says they must never endanger chinese unity, and will now be closely monitored by police. It also bans them from recruiting or fundraising. Chinese officials defended the restrictions at a News Conference in beijing. translated there are a minority of foreign n. G. O. s, that through the means of funds and some methods, will manage to harm chinas National Security interests and some other illegal criminal activity. In this way, strengthening control including handling this illegal contact, is something that we should also do. Sreenivasan u. S. And european officials have criticized the law as the latest move in a growing crackdown by the ruling communist party.

An economic backlash against North Carolinas lgbt bathroom law, and much more. Sreenivasan we return to the bombing of the hospital in the syrian town of aleppo. According to reports 27 people were killed. With me now is pablo marco, middle east Operations Manager for Doctors Without Borders which supports the facility. Pablo, youve probably been in touch with your colleagues on the ground there. Whats the latest theyre telling you . All right, so we are speaking with the head of the hospital hours ago. He was telling us how all the events unfolded. He explained that 10 00 p. M. Yesterday, two bombs fell close to the hospital, then a lot of wounded people were driven to the hospital, directors were waiting at the gate of the hospitalsnoabout the news of the families. Then the bomb fell at the entrance of the hospital in the emergency room and a massive killing of people. Sreenivasan it was staged so the people would rush to the hospital, there would be more people there, and a secondary attack. We cannot assert this but all elements show that this attack was, as you say, staged to promote the maximum number of citizens killed. Sreenivasan tell me what kind of impact it means to tot have this facility in this corner of the city. Well, there are very few facilities working in aleppo. We need to know around 95 of the doctors in aleppo have either fled or been killed by bombings, already. So every single facility that is destroyed or every single doctor that is killed has a massive impact. This hospital was a Reference Hospital for pediatrics and in, in addition, one of the key hospitals for internal medicine. So very, very high impact. Sreenivasan so how many people, roughly, are treated in this facility, and how long, the wait lines, so to speak . There are probably not that many option force people in that area. Exactly. We were talking with the director. He was telling us all the wounded have been taken to the hospitals, but, of course, they are absolutely overwhelmed, as you can imagine. Sreenivasan what does it mean for this hospital to be supported by Doctors Without Borders . Whats your involvement there . I have been working with them for at least, now, three years. Were in aleppo. Were going to the hospital every other week for technical advice, technical equipment. Last year the hospital was attacked with bombings and, at that time, after the request for support, we provided new equipment to restart the hospital. Even until this week, we were doing that with them with the other nations. Sreenivasan are you sending more doctors into this area . So well keep supporting these hospitals, if we are able to make it happen, to make it work again, and well keep supporting many other hospitals in aleppo city. At the same time, something important we need to know is that we think it is really important that there is an independent investigation to clarify who has been responsible for this attack and if this attack has been delivered, some elements can point out. There will be a resolution for the city council in the next days regarding the protection of hospitals and this terrible event shows us that this resolution is more important now than ever. Sreenivasan will other aid agencies help fill the gap . Who else supports this hospital . What happens to the people in the region who no longer have access to any facilities . There is not much more anyone can do until the attacks on the hospital are finished. We understand that anne is afraid to go to aleppo now. Doctors, the medical staff, they are a target here. Hundreds have been killed and its really difficult to replace those having been killed in this attack yesterday. Sreenivasan do you see this as a pattern to target medical facilities not just in syria but other parts of the world, too . Yes, we were talking a few minutes ago about the attack in afghanistan. Weve had several attacks in yemen in the last month, especially in the city where there have been tens if not hundreds of attacks in medical facilities, and this trend is worsening in the last, say, six months. Sreenivasan there was that other story in the news today. Does your organization have any sort of a response yet to the u. S. Government deciding to discipline 16 members of the u. S. Military in that tragedy that affected the hospital in kunduz last year, the Doctors Without Borders hospital . Yeah. So what i will say is that, since this terrible event happened, were asking the u. S. Government and other actors that we think really that we need an independent investigation to clarify what has happened in this attack. The u. S. Government has carried out their own investigation, but, of course, it hasnt been independent, and we keep asking for this investigation to happen. Sreenivasan all right, pablo marco, Doctors Without Borders. Thanks so much for joining us tonight. Thank you. Byebye. Woodruff an unlikely character took center stage on the Campaign Trial today. Former speaker of the house john boehner inserted himself into the conversation. The Newshours John Yang reports. Reporter for ted cruz, its all about indianas republican primary next tuesday, and trying to stop donald trump. His challenge today, though, came from former House Speaker john boehner. In congress, he repeatedly butted heads with texas senator cruz for backing government shutdowns, among other things. The Stanford UniversityStudent Newspaper reports boehner newspaper reports boehner used unvarnished language about cruz during a campus speech. What about ted cruz. Lucifer in the flesh. I have never worked with a more miserable bleep he allowed his inner trump to come out. He allowed his inner trump to come out. Reporter cruz fired back, cting boehner and trump as creatures of the washington politics hes been railing against. John boehner in his remarks described do trump as his texting and golfing buddy. So if you want someone thats a texting and golfing buddy, if youre happy with john boehner as speaker of the house and you want a president like john boehner, donald trump is your man. Reporter trump was in indiana, hoping the Hoosier State will get him even closer to the republican nomination. We dont have a long way if i can win in indiana. If i win, its over. cheers and applause if we win in indiana, its over. Reporter trump got endorsements today from two House Committee chairmen floridas jeff miller of the Veterans Affairs committee, and pennsylvanias bill shuster of the transporation panel. But the frontrunner took heat for his Foreign Policy address yesterday. In a phone interview with the today show, he was asked about criticism that his plan to fight the Islamic State is light on details one of the big tenets of my speech yesterday was the fact that i said, and very, very strongly, that we need unpredictability, we need to be omewhat unpredictable. Reporter as for the democrats, Bernie Sanders was in oregon, which doesnt vote until midmay, while Hillary Clinton stayed off the til. For the pbs newshour, im john yang. Woodruff after big wins on tuesday night, Hillary Clinton and donald trump have commanding leads in their fight for the president ial nominations. To make sense of the delegate numbers and how they shape the road ahead, we are joined by domenico montanaro, Political Editor for npr. Welcome. Thank you, judy. Woodruff lets start with the democrats. Where right now do Hillary Clinton and Bernie Sanders stand when it comes to delegates . Hillary clinton is far ahead after the sweep in four of the five contests on tuesday and after her big win in new york, youve got Hillary Clinton with 2165 de delegates, as you can s, to Bernie Sanders 1357. She is 91 of the way there to the total to that magic number of 2383 that she needs. Woodruff you were telling me compare that to where barack obama was, then candidate barack obama in 2008 at this point. There is been a lot of talk how close this race this and certainly Bernie Sanders message has broken through. He makes a clear and understandable message. Hillary clinton has had to use some of that message. But when you look at the numbers, Hillary Clinton is up to 333 pledge delegate leads. Take out the superdelegates which sanders supporters s. A. T. When we talk about those because they feel they can vote any way they want, but 333, barack obama never had a lead higher than 114. He wound up with a 69pledge delegate lead. Hillary clinton is leading with 333 in pledge delegates is actually almost 100 points higher than where barack obama finished with ledge delegates and super delegates combined. Woodruff there are 14 contests to go for the democrats ten states four territories including the district of columbia. How do you see this playing out . Woodruff Hillary Clinton, barring something extraordinary, will be the democratic nominee, because shes 91 of the way there, she could lose every remaining contest by 20 points or more and still win the majority of delegates. When you factor in superdelegates its over 80 . So very difficult for Bernie Sanders barring something extraordinary. In the final contest, she has to get to 2383. There is the possibility she could do it as early as may 17 when oregon and kentucky go, but that would mean she would need another 120 or so superdelegates to come out in favor of her. There are 159 uncommitted at that point, 158, thereabouts. More likely shell do it on june 7 when california votes and the huge cache of votes they have. Woodruff lets switch t
