Civilians, families trudging across the bridge and part of this kind of ad hoc humanitarian corridor thats come together for people by the thousands, by the tens of thousands to flee the isis militants and make it here to Iraqi Kurdistan to safety. Theyre basically routing themselves through a kurdish enclave in syria. Theyre being helped by the group that rules that enclave which is known throughout the region as the Kurdistan Workers Party who have provided vehicles. The refugees tell me, and then they get repatriated across this bridge into Iraqi Kurdistan. Some of these people have escaped from mount sinjar, from that place that has become a bit of a trap for people fleeing the city of sinjar to escape account isis militants. They traveled instead of the way we did by helicopter yesterday, they trudged 10, 15 hours from the mountain under the protection of the Kurdistan Workers Party to syria and one young man that i talked to, wolf, he said that he buried two of his brothers, his infant brothers who he says died along that ordeal, ta long journey. Very difficult to hear that are to imagine what that man had gone through to make his way here to Iraqi Kurdistan where on roadsides, in abandoned buildings, these people who have made it here to safety are now camping out under the stars tonight provided some food by volunteers by a few aid organizations. But theyre basically refugees sleeping on the street right now here in the city. Ivan watson on the scene for you. Well get back to you. Stand by. Meanwhile, theres chaos in iraqs capital. Baghdad was rocked tonight by a fair of car bombs that left at least nine people dead and a political standoff continues. The outgoing Prime MinisterNuri Al Maliki is vowing to hold on to power even though the United States and now even iran are both backing his designated successor. Lets go live to Nick Paton Walsh in baghdad for us. First of all, the bombings in the iraqi capital, what can you tell us. Reporter well, shaken here almost by a plume of smoke, an explosion a few blocks away in the district. Were now looking at a death toll from two explosions in roughly a similar area, shia districts targeted in the capital as at least eight people killed, dozens potentially injured. It shattered a tense quiet. Everybody i think seeing in the writing on the wall for Prime MinisterNuri Al Maliki apart from him, iranians as you say, john kerry encouraging the Prime Minister designate Haider Al Abadi to get on the job as quickly as possible. French accusing Nuri Al Maliki of being behind the crisis in iraq itself. Even the Saudi Arabians suggesting that they want Haider Al Abadi to become the Prime Minister here. Nuri al maliki defiant saying he doesnt want the military to be involved in politics here or he has suggested he might use force to stay in power. We saw a potential window of conciliation the past few hours. Haider al abadi, the man nominated to replace maliki saying nuri has a place in iraqs future. Perhaps a bid to try and calm tensions here but bob all, Nuri Al Maliki not stepping back from the plate. There was a very disturbing moment today. An Iraqi Military helicopter trying to aid some of the minorities, christians, yazidis up in the north that Iraqi Military helicopter crashed apparently into something the pilot was killed, a reporter for the New York Times alissa rubin was injured along with a photographer for the New York Times. There was a parliamentarian, the yazidi parliamentarian in the Iraqi Parliament who was on board. Quhak you tell us about that helicopter, that chopper . What do we know what happened to it . Theyre all insisting there was no hostile fire but it was some sort of technical or mechanical failure. Thats really all we know from the Iraqi Military. They said it came down because of a technical failure and the pilot died. Many injured including an mp, a number journalists, alissa rubin suffering a concussion and broken wrist according to her own newspaper. Many other injured too on board. Weve seen the pictures how they fly over territory infested with isis militants often having to fire down below for their own protection as they travel. Its clearly a very dangerous place but it does seem they use the phrase technical failure. Ive heard that used in the past in combat zones, perhaps a ux mix for when helicopters may come under attack. Theres no independent suggestion that happens here. Were talking about very old russianmade helicopters. Very difficult conditions. Dust heat make the chance of a technical problem high, as well. In this case, only one person lost their life. It shows you how peril lous these rescue missions are, wolf. Where are you in baghdad right now, give us a flavor around that socalled green zone where the u. S. Embassy, the largest u. S. Embassy in the world, there are literal little thousands of americans there, contractors, diplomats, military personnel. Over the weekend we heard reports malikis loyal troops were moving thanks into that area looking like he was going to have some sort of coup detat if you will. Has that situation eased now that all the pressure is mounting on him to disappear, if you will . Its certainly not mounted since their first nights report of thanks in the green zone. Driving in from the airport we saw soldiers from the Army Division known as the golden division, very loyal to Nuri Al Maliki. A slightly heightened sense of police on the street. A different atmosphere in the city as various militias try and calculate where they fit into the constantly changing political environment. Its very quiet indeed. Very little traffic. Some residents describing to me its a city definitely on edge because the political vacuum here may ease in the days ahead if maliki reads the writing on the wall. Its the capital and isis have been breathing down its neck for a matter of months. The explosions each time they happen, people wondering is this the beginning of something new. A lot of fear for residents still in baghdad. Nick, be careful over there in the iraqi capital. Well have much more on the story coming up including reports the u. S. May be on the verge of deploying many more military advisors to iraq right now. Well go to the pentagon for that.

When i finally told my doctor, he said my crohns was not under control. He said humira is for adults like me who have tried other medications but still experience the symptoms of moderate to severe crohns disease. And that in clinical studies, the majority of patients on humira saw significant symptom relief. And many achieved remission.

Serious, sometimes fatal infections and cancers, including lymphoma, have happened; as have blood, liver, and nervous system problems, serious allergic reactions, and new or worsening heart failure. Before treatment, get tested for tb. Tell your doctor if youve been to areas where certain fungal infections are common, and if youve had tb, hepatitis b, are prone to infections, or have flulike symptoms or sores. Dont start humira if you have an infection. If youre still just managing your symptoms, ask your gastroenterologist about humira. With humira, remission is possible. Fly. Be free. Well, i guess well have to have a quick burial at sea then. Amazing talent. The other breaking news were following, new details revealed by authorities on the death of the actor, comedian Robin Williams. Ted rowlands is in san rafael, california for us. Whats the latest over there . What have we learned . Well, wolf, an autopsy was done on mr. Williams body this morning. The coroner came out and briefed us on the cause of death and some details of surrounding his death. He apparently has died of suicide and he has apparently hung himself. That is what the conclusion is at this point. Investigation is still going on. Theyre waiting on toxicology reports that will take two to five weeks. At this point, he appears to have hung himself in a room by himself. He was found by a personal assistant around noon yesterday. Mr. Williams had been seeking treatment for depression. Mr. Williams was last seen alive by his wife at approximately 10 30 p. M. On august 10th, 2014 when she retired for the evening in a room in the home. The preliminary and i again say preliminary results of the forensic examination revealed supporting physical signs that mr. Williams life ended from as a fixfictionia due to hanging. It was emphasized that Robin Williams was receiving help for depression. No funeral arrangements at this point have been made. But his death is being Health Across the country and especially here in the San Francisco bay area where he called home for many, many years. What a sad sad story indeed. Ted rowlands, thanks very much. Tom foreman is taking a closer look at Robin Williams extraordinary life and career and joining us for this part of the story. The reaction, of course, is a very broad and deep loss of Robin Williams because out of all the comedians out there, those do diagnose political comedy and thoughtful and manic comedy, he was a category unto himself touching all of those areas and gathering new fans decade after decade. Greetings. From his first moments in the 70s hit happy days as an alien visiting the 1950s, Robin William was a time traveler. I couldnt help it. You understand . I honestly regret it. And once he found the spotlight for almost 40 years, he never left it. You wreck, stalagmite, stalactite, thanks. Whether mocking a president for the College Crowd on sat the night live or leaping into a film for all ages like jumanji, he engaged each new generation with such energy. It always seemed as if he had come specifically for them. What year is it . It was brand new. No, what year is it . 1995. Remember . Undeniably, had his range made it possible. In films like mrs. Doubtfire, he let loose was broad physical comedy. Oh, sir, i saw some angry member of the kitchen staff. Did you not tell him there was a run by in aladdin, his extraordinary ability to conjure dozens of voices made the again i in the lamp brilliant. Mr. An lanza. While we your pleasure be. Let me you aint never had a friend like me. And yet, he could just as convincingly play it straight in movies like dead poets society. Gather ye rose while y email. A latin term for that sentiment is carpe diem. Who knows what that means . Who knew . He did. Because williams seized each day, each moment as if it were his last. Whether entertaining troops, raising money for charity or teaching kids on sesame street. When i breathe you can hear the air go in and out. Sometimes you can even see it. Like this. Happy new year perhaps one reason so many people loved williams so much was that age and worry and time itself seemed to pass him by. Like his character in hook, he was the boy who never grew old and in doing so, the man who kept us all a little younger. Kept cuss all younger. As we went through all these clips today, i was stunned by the breadth of his work. Ive been aware of it, but he has been so prolific. He has produced so many movies, been on so many shows, done so many interviews, it almost defies believe he had this range of talent over such a long period of time. Thats how he gathered so so many fans were so troubled by the way had his life came to an end. Its simply amazing when you think about it. A huge talent. Tom, thanks very much. Robin williams was a guest on inside the Actors Studio back in 2001. Theres one particular moment from that interview that stands out now in light of his death. Watch this. If heaven exists, what would like to hear god say when you arrive at the pearly gates . Theres seating near the front. The concert begins at 5 00. It will be mozart, elvis and one of your choosing. Or just a nice to know theres laughter, that would be a great thing just to hear god go two jews walk into a bar. James hipton is the host of inside the Actors Studio and joins us now on the phone. James, thanks so much for joining us. He was on your program. You spoke with him about his struggles, addiction. He was pretty open about all of that. Did you ever see, though, the pain behind that humor . No. No, because what he did was remarkable. Obviously, he was tormented. All his life apparently he suffered from this problem. But what he did was he kept that inside. That was for him. What was for us was the joy. He gave us nothing but pleasure, nothing but happiness. And he reserved for himself the harder part of his life. In the end, it became too much to bear. That is a very sad fact. What was it like interviewing him . Well, for one thing, he came out on the stage inside the Actors Studio and off he went, bang. He just started. And he didnt stop and he just kept going. Of course, i sat back enjoying it like everyone else. Finally i raised my hand after about 7 1 2, eight minutes. He said what do you want . I said its time for my first question. That was what happened on the ho. Of course, the most famous moment in the history of the show was of the 20 years of inside the Actors Studio was the pink pashmina he took from a would you think woman in the first row. When i said to him, look, robin somethings happening here i dont understand that none of us are capable of understanding. Whats going on inside your head . Are you thinking faster than the rest of us . What are you doing . And he just laughed and he said, well, i cant explain it but ill show you. He took the pashmina and in the course of the next six or seven minutes, he used the pashmina in various ways to become an indian film director, an iranian woman, a gay rabbi, the iron chef, and finally at the end of it, he folded the pashmina and he back and forth in front of his face with its tassels and came he through with his face and he was a car emerging from a car wash. That is something that cant be taught, that the cant be learned. You have to be born with that kind of jean,ious. Just ad libbing. These were not planned routines that he had done hundreds of times before, right . Im sorry, i didnt hear. You this is not planned routines he was doing. This was all off the cuff ad libbing improvisation. Let me Say Something once and for all about robin. His life was an improvisation. In aladdin, he played the genie. The genie trotted out all the things he needed to learn in order to proceed with his life. In the course of that threeminute scene, do you know how many characters he created in three or four minutes of that scene . 52. 52 separate discrete complete characters were created by him alone in a studio in front of a microphone. They animated to it. Theres only one word for it, thats genius. I remember having the privilege of seeing him do standup. Here in washington, George Washington university a few years ago. I was sitting up close. Ill never forget, it must have been two hours and he was making all of us laugh so hard. But he was working so hard. He was so passionate. He was sweating. The towels were coming out. They were soaking because he gave it all of that. Im sure you noticed that, as well. Well, he did his standup act in front of a Water Bottles and he would go through 10, 20, 30 bottles of water in the course of a single evening. He gave us everything he had. He withheld nothing. The only thing that withheld from us was his suffering. And in the end, he paid for that. That is a sacrifice to making what an amazing, amazing talent. All of us are so sad that we have to do what were doing right now. Remember him because we would have enjoyed his performances. Serious and comedic for many, many years to come. James, thanks very much for sharing thoughts an with us. We appreciate your joining us. Youre very welcome. Thank you. Thank you, japs lipton inside the Actors Studio. Please be sure to tune in later tonight for a special cnn spotlight remembering robin, that will air 11 30 p. M. Eastern right here on cnn. Were going to have much more coming up. His life and his legacy. Watch this. I do
