Captions by vitac www. Vitac. Com fear and tension are growing by the hour in iraq right now with isis militants seizing city after city, town after town. The sunni fighters now have a direct line to the western outskirts can of baghdad where shiite forces say theyre prepared to fight to the death in a sectarian battle for control of the country. In the middle of it all, a surprise appearance today in baghdad by americas top diplomat. Were covering all thing ands of the crisis with our analysts and correspondents inside iraq as well as here in washington. Our Senior International correspondent Nic Robertson is in baghdad and he begins our coverage this hour. What is the latest . Well, wolf, john kerry has just left the city here. He got agreements from the leading politicians here to stay committed to a timeline for forming a new government. That is quite a protracted process. In the meantime, isis fighters continue to make substantial gains in the country all the way up to the border with jordan close to the border with saudi arabia. Sweeping in now from the border from syria, as well. [ gunfire ] snooks isis forces continue sweeping iraq and closing in on baghdad. With substantial new gains in the north and west of the country. Taking control of more towns and an iraqi air base in tal afar. Isis now controls at least 70 of al Anbar Province where u. S. Troops waninged a deadly battle against insurgents just a few years ago. But iraqs army is unable and in some cases unwilling to stop the i. C. E. Advance. A senior u. S. Defense official tells cnn the u. S. Believes multiple iraqi divisions outside of baghdad have dissolved and are plagued by problems in morale, leadership, training and equipment. With the crisis worsening daily, secretary of state john kerry made an unannounced trip to baghdad where he met with iraqi leaders including embattled Prime MinisterNuri Al Maliki. Kerry said al maliki has agreed to a july 1st deadline to begin forming a new government. A requirement for u. S. Support in fighting isis militants. The support will be intense, sustained, and if iraqs leaders take the necessary steps to bring the country together, it will be effective. And with i. C. E. Forces moving closer to baghdad each day, kerry said u. S. Strikes could come at any time. Make no mistake, the president has moved the assets into place and has been gaining each day the assurances he needs with respect to potential targeting and he has reserved the right to himself as he should to make a decision at any point in time if he deems it necessary strategically. And another key step in that process now falling into place, as well. Immunity from the prosecution for the military advisors who will come here to assess the strength of irngs military where its weaknesses are, what equipment they need. We understand this time it will be initially at least six 12men teams, wolf. Ill ask it to you, nick, what does it say that 11 years after u. S. Forces went into iraq, remove Saddam Hussein from power, the secretary of state of the United States still cant visit the capital of baghdad publicly, make announcement that hes coming. It all has to be done mysteriously, secretly because of the security dangers. What does that say about all that has happened over the past 11 years . Arguably, wolf, that this is the worst situation that he could be coming in because those isis fighters are very close to the International Airport where he flew into and therefore, theres, you know, the threat to him was ever more real than it was in those 11 years. It is a stark statement that after leaving iraq, that it hasnt been able to be with all the help particularly the help given to the military here, that it isnt able to secure to provide a secure place where a visiting secretary of state can come in with a higher degree of security than he has at this time. What were seeing in iraq at the moment is some of the worst fears of diplomats did being realized the fact that the countrys dividing into three parts. Very hard to put it back together. A terrorist force digging into the countryside where once u. S. Troops has managed to quash and push out al qaeda. It is, if you will, a terrible statement of just how far back even iraq has come in that time, wolf. All that effort, all that blood and interest esche and people are asking understandably so what for. Nic robertson in baghdad, thanks very much. Be careful over there. While isis is made up almost completely of sunni fighters many sunnis do not support the militants au though they share their hatred of Nuri Al Maliki. Arwa damon is joining us from frommer bill in iraqs autonomous kurdish region. You talking to sun sunni leaders. What are they telling you . Reporter well, wolf, this force that is making its way towards the capital of baghdading is a very complex tapestry of different insurgent groups. On the one extreme, we have isis the Islamic State of iraq and syria, its end goal toll create an islamic caliphate. All groupses are united under a determination to make sure maliki is removed from power. These various tribal leaders have been readying themselves for this batting for quite some time. Around a year ago we traveled to the sunni heartland of al Anbar Province. The highway transformed into a demonstration ground against shia Prime MinisterNuri Al Maliki. The tribes were getting ready for battle should iraqi forces try to enter. Translator weve been ready for a long time. Were certain al maliki is a liar. The political process is just a game. Our weapons arer from, light medium and on up. But he also vowed the tribes would not again be a nuturing ground for terrorism. His tribe was among those that eventually allied with the u. S. Turning against al qaeda in some of the darkest days of the occupation. So what happened . Isis is trying to ride the wave of the sunni revolution, trying to exploit it, and we wont accept this. But to a certain degree, they have. For now. Translator its not in our interests to fight a variety of groups. We dont have the capability to fight everyone. The problem is with maliki. Isis is killing and isis has an agenda but all the shia militias right now are wearing an official iraqi uniform and are killing iraqis. Everyone is focused on isis, the tribes will not ally with i was. Problem is, sunni insurgent groups and the tribes are not all united. But iraqs sunni population does have genuine grievances. Translator America Needs to not look at iraq through a single lens. There is a real revolution, real revolution. America needs to listen to us. We dont have an issue with anyone. We just want our rights. We have a right to live here. And he warns America Needs to remember something very important from its devastating era in iraq. Translator i. C. E. Is going to open a door in iraq that cant be closed. We are aware of this. You cant stop isis without the tribes. America shouldnt think that the maliki government can stop isis. Maliki is the real danger to us. We can get rid of isis whenever we want. And rest assured, we will fight them. That might prove tougher than he boasts. Already in many areas like mosul, isis is clearly the one in control and calling the shots. Having already opened the door to this new bloody face of the countrys history. And while secretary of state john kerry following his meeting with Nuri Al Maliki was speaking about the need for an inclusive government at this stage, it seems as if maliki is not the man who can do the job. Also today speaking to Christiane Amanpour was the president of Iraqi Kurdistan who made it very clear he believed maliki needs to go. Seems almost everyone seems to think Nuri Al Maliki must go in iraq. Thanks very much for that. Up next, the growing threat of sectarian civil war in iraq. Thousands of shiite mill lishianmen are marching through the capital of baghdad vowing to fight sunni forces to the death, some wearing suicide vests.

A massive show of force as an estimated 20,000 Shiite Militia men march through the streets of the capital bearing weapons, including what looked like suicide vests. Their message . Theyll fight to the death to keep the mostly sunni forces of isis from taking baghdad. Mike giglio is the middle east correspondent for buzz feed. He saw all of this unfold and joining us on the phone right now from baghdad. So, tell us what it was like, mike. You were there, you saw this demonstration. Give us a little feeling for what was going on. Thanks, wolf. Yeah, it was really an amazing it show of force. I was shocked by how many people were there. The ap estimated 20,000. It could have been much more than that. And almost all of them armed. Some very heavily. You saw ak47s to rpgs and rad rockets in the back of pickup trucks. It was a pretty impressive show of force and a loud message. What does it say about the situation in iraq right now that a demonstration like this, these Shiite Militiamen are marching through the streets of the capital of baghdad . It says that the iraqi army really doesnt have control. And that the local population really doesnt have any faith in the iraqi armys ability to defend them. So people are taking it upon themselves to take up arms and to send a message themselves to the militants in the north saying we can defend ourselves if the government wont. There was one poignant picture, very dramatic of some of these marchers war showing it right now wearing what looked like suicide vests. Obviously, they were sending a message wearing these vests. Were they real suicide vests or sort of artificial . I dont think they were rigged up to blow. Im not sure whether those were actual explosives or not. They breezed by pretty quickly. Im pretty sure that was a suicide battalion and those people were marching to send a message when it comes time for this, were ready to die for the cause here. Isis is really driving regular iraqi army troops, security personnel into desertion. Theyre just running away interest these guys. Explain. Youve been there for a while. Explain whats going on. Why is the Iraqi Military simply crumbling . I think its more deep seed seeded than weve realized an this point. I spoke to an army captain from the fallujah. Isis took fallujah in january. He told me the first thing isis did when they took the town was to go door by door and threaten the families of anyone in fallujah who was a member of the Armed Services or the police force. And then captain had taken his family out of the city. But he was hiding here in baghdad. And he thought that isis knew where he was even here. He told me that he thought they had databases of everybody in the Security Forces and the armed forces in the country. That they knew their movements it, knew their ranks and sears and knew their families. I ran that by some analysts and some politicians here. They said thats their understanding of isis capability, as well. When thats going on and these people really have fear in their hearts, they know its not just going to be a battle on the battlefield. Their families are in danger, as well. I think theyre terrified. Mike giglio from buzz feed. Be careful over there. Its a rather dangerous situation as we all know. Thanks for joining us. Lets get more. Retired u. S. Arm colonel derek harvey is joining us, former advisor to David Petraeus in iraq. Thanks for coming in. Good to be mere. Did the Iraqi Government underestimate isis . I believe they did underestimate isis and the nature and character of the leadership and the vision of the isis campaign that started about 1 months ago with shaping operations to undermine the Security Forces as outlined in the preamble. It looks like extremists among the sunnis isis, extremists among the shiites these militiamen marching through baghdad seem to be taking charge right now what we would call more reasonable moderate middle types seem to be scared. Theyre not really participating any more. Is it too early to write them off . This is going to be a clash between Shiite Militiamen who are extreme loyal to iran for that matter versus the sunni militants who are i. C. E. Terrorists. It looks like the extremes are dominating. Isis is clearly the vanguard of the sunni arab resistance. It is much broader and deeper than that. Its got multiple insurgent groups like duris organization, the iraqi islamic army and other groups. Plus many of the former sons of iraq or the awake neng members have join the in the fight. You spent five years in iraq serving there with general petraeus among others. Heres what the kurdish, regional kurdish president Massoud Barzani told our Christiane Amanpour today. We havent remain hostages for the unknown. The time is here for the kurdistan people to determine their future and the decision of the people is what were going to uphold. Are we on the verge of seeing a partition of iraq into a kurdish autonomous area, a sunni and shia area . I think were on the verge of that unless strong measures are taken not only by the United States but the International Community to shape a change in government towards a you know aught government and try to put this back together again. Part of this has to be reaching out to the sunni Eric Community and driving a wedge between moderate sunni arabs and isis. You say isis really the heart of isis isnt in the iraq but its in syria right now. If the u. S. Where is to start launching air strikes against isis targets in iraq, it had be a waste unless the u. S. Did the same thing in syria. The best outcome would be to link syria and iraq into one campaign plan. The iranians see it as one battle front and we should, too. The heart, the brain and the Resource Base for isis is in syria, northeastern syria. I suspect the American Public has no great appetite to get involved militarily like that. A Huge Campaign in syria and in iraq. But well see, colonel, thanks foech for coming in. Glad to be here. Thanks for your service.
