As new advances by the Islamic State forces threaten minority christians and yazidis. Thousands have fled in terror, and are stranded on sinjar mountain without food or water. When we face a situation like we do on that mountain, with innocent people facing the prospect of violence on a horrific scale, when we have a mandate to help, in this case, a when we have the unique capabilities to help avert a massacre, then i believe the United States of america cannot turn a blind eye.

Woodruff the white house said again today the extent of future us support depends on the formation of an inclusive Iraqi Government. Woodruff well have much more on all this including an interview with the Deputy National security advisor at the white house right after the news summary. The three day ceasefire between israel and hamas ended today and the fighting resumed. Militants in gaza launched more than 50 rockets into israel, starting before the truce expired. At least two israelis were wounded. Israel answered with air strikes in gaza. Palestinian officials said at least five people were killed, including three children. The new fighting cast doubt on whether negotiations in cairo will continue. The negotiations in cairo were based on a premise, and that premise was an unconditional cessation of violence. When hamas broke the cease fire, when hamas launched rockets and mortar shells at israel, they broke the premise of the token. There will not be negotiations under fire. The way will not be closed for the continuation to have the palestinian negotiations and the ball is in the israeli court. Its on the occupation to decide and our people, god willing, are ready to deal with all the choices. Woodruff hamas has demanded that israel end its sevenyear blockade of gaza. The israelis say that wont happen, unless hamas agrees to disarm which the militants have rejected. The rival president ial candidates in afghanistan agreed to a power sharing deal today. Abdullah abdullah and ashraf ghani committed to resolving the disputed election and inaugurating one of them as president by months end. Secretary of state john kerry announced the agreement in kabul. The agreement is an opportunity for both candidates to do what they just said, which is move beyond the campaign and into the process of governing. For afghanistan, the stakes are high. It will depend on them and the United Nations to help move this forward appropriately. For more on the agreement, we turn to n. P. R. Correspondent Sean Carberry in kabul. I spoke with him a short time ago. Sean, thank you for joining us again. First of all, tell us, what is this arrangement that secretary kerry has worked out . Well, today is really a recommitment of the agreement that was struck last month when secretary came. There were two pieces to it. One was the 100 audit of the ballots cast in the june 14 election, and both candidates will abide by the results of that audit. The second part is a political agreement where the winner will form a government of national unity, and there will be a role for the loser in that government. So these are the same basic terms that were agreed to last month. What they did today was issue a joint communique reaffirming their commitment to these two principles, and they flush out a couple of details. One is they said they will make sure the audit is completed by the end of august with the goal towards having a new president in place before the n. A. T. O. Summit on september 4. And they put a little more detail to the political agreement, but there is still a lot of elements of that that they say they need to flush out. Woodruff does it appear abdullah and ghani will stick to this this time, which we thought would happen last time . Right, and that is the question. People thought last time secretary came, in secretary kerry solved the issues, that this would be a smoothsailing passage to getting a new president in place. But shortly after secretary kerry left, the deal started to unravel, they started to squabble about some of the terms, so secretary came in again and calmed things down. The hope is that this will be enough, that one longtime political analyst i spoke with here today said she expects there will be more bumps in the road and a continued need to rebroker the deal as things go forward. Woodruff very quickly, sean, when will we know if this is working . Well, presumably over the next few days as the audit progresses, it will be clear whether or not its picked up speed. If you start to see candidates balking at terms or prolonged arguments, then that raises the question about whether or not someones going to have to come in and put more pressure on the two of them again. Woodruff Sean Carberry joining us from kabul, we thank you. The World Health Organization declared the Ebola Outbreak in west africa an International PublicHealth Emergency today.

Woodruff to find out more on the obama administrations decision to launch airstrikes inside iraq and air drops of humanitarian aid, i spoke to white house Deputy National security advisor ben rhodes a short time ago. Ben rhodes, thank you for joining us. The Islamic State fighters are saying that the u. S. Airstrikes are not hurting them at all, that theyre going to keep going. How much damage are the strikes doing . Well, we wouldnt expect the i. S. I. L. Fighters to say anything different. The objective is to stop advance of i. S. I. L. That threatens, and we have been having an impact. We have hit targets they have been shelling and advance aing toward the city and we want to create a periphery where they cannot threaten the people or the city. The yazidi m Minority Group e stranded. There was a report today several hundred yazidi women have been taken hostage by i. S. I. L. How far does the administrations commitment go . Well, we have been very disturbed by these reports for a period of days, included executions of yazidis at the base to have the mountain and taking women and forcing them to convert and marriage and horrible conditions on the mountain. There was a water drop and we are going to continue the humanitarian air drops to reach the population on the mountain. At the same time, we need to work to get the yazidis into a safe space where they can receive more Sustainable International support to solve this humanitarian crisis. Were committed to saving as many lives as we can and preventing what would be an act of genocide in an effort to wipe out the yazidi population. Woodruff both the yazidis and the population in erbil, how far will the u. S. s commitment go . Will the u. S. Be there no matter what . The limits the president placed on the mission, for instance were not putting american boots on the ground to be engaged in combat in iraq again but we believe we can achieve object nighs the air, hit target that move toward the city and creating a Protection Zone for erbil and our people, and on the mountain humanitarian aid drops, and hit any i. S. I. L. Targets if we see people threat nick the mountain. That should create space to come up with a solution to provide safe panels and space for the yazidi people. Woodruff did the administration underestimate the Islamic State fighters . I think what happened is they posed a significant threat for years. They used to be al quaida and iraq, so they have been around. I think what happened is they rapidly ramped up capacity for two reasons one, they had room to operate in syria because they had conflict there and they could operate across a border that was eva evaporating between iraq and syria, and two, as they made advances, they were able to get stocks of heavier weapons, making them more capable, and thats what spread some of the lightning strikes weve seen from them in the last several days where they pushed back the Peshmerga Forces. We believe with our air power, the peshmerga and Security Forces have time to regroup, that they cannot take the fight to mosul and they cant withstand an Effective Security force taking the fight to them. Woodruff i know some of your critics coming from the Republican Party says yes, its probate what the administration is doing, but they dont see a strategy, that just talking about humanitarian aid when you have a determined enemy like Islamic State is not going to be enough, that the Administration Needs to do and plan to do more. The strategy is simple we havwehave survivors on the groud are protecting the people and helping a humanitarian crisis. They put together an inclusive government in iraq so that the sunnis see the government in baghdad as a partner and not adversary. That opens up space for countries in the region to provide more support for the Iraqi Government and then with the iraqi forces in the lead and Security Forces from the north and support in the region, thats the strategy that will work. A lot of our critics think there are u. S. Military solutions we can impose on to iraq. I think the lesson the last decade is the u. S. Military cant impose a political outcome on iraq, only iraqis can do that and thats what we impress them to do. Woodruff what gives you the confidence the strategy will work . I think, frankly, while i wouldnt want to predict with 100 certainty what an outcome be will be in iraq, there has been a shocko the system in iraq. Iraq had gotten complacent and fallen into sectarian divides but israels advances provided a wakeup call and weve seen in the government progress. A new kurdish president nominated, a sunni speaker, discussions around a Prime Minister. So we see that coming together. As people regroup, this can unit iraqis. Doesnt mean a perfect outcome with so many divisions and history, but we can push back on the gains i. S. I. L. Made in the last several weeks. Woodruff and make gains with people on the other side that say this is a slippery slope . We have set clear objectives for the militaryo the United States commitment, protecting the people in iraq which we would do anywhere in the world and solving a humanitarian crisis is tens of thousands of people stranded on the mountain. Thats our military mission and what the president authorized. At the same time, were affecting political outcome through Security Assistance and equipment training, thats the longterm play. And people who are concerned about slippery slope, were not putting u. S. Troops back in combat in iraq. We had 150,000 troops when he took office, we removed them and only have a small advisory presence. Were not going to get back into the heavy u. S. Footprint weve had in the last decade. Woodruff thank you. Thank you very much. Woodruff Hari Sreenivasan has more on the iraq story. Reporter for reaction to the latest developments in iraq and the u. S. Response we get two views.
