The separatists saying very much the same thing. Now there seems to be a workable formula. But the headline here is and were hearing this from the German Foreign ministry that not everything was agreed a lot of fine details, issues that have been problematic in the past yet to become clear how theyre going to be resolved. One thing the germans are saying is the border issue between the separatist part of ukraine and russia that there is some agreement on that but were yet to get all the details here yet, alisyn. Nic, thank you so much for that background. Before we lose you, can i ask you a question. I know were waiting on information. What do we know minsk happened already, russia violated it already. I know theyre putting a specific date on ceasefire this time. What are the points that are giving some home for optimism . The optimism here is based on the fact that they came to try to get a ceasefire to end the bloodshed, how we can be optimistic about Going Forward, i think we need to be extremely concerned right now about how this is going to hold. Because we dont have the details. The devil is in the details. How much autonomy the separatists get. What was agreed as you say last september broke down on the battlefield, its two and a half days before the ceasefire comes into effect. The separatists have said there are more towns that they want to take. So you know theres a lot of places that this can still go wrong. And were not seeing anything yet that can tell us yes, this is different this is changed, and it can work. I think there needs to be a level of skepticism and concern at this stage chris. I remember standing in kiev with you and you telling me how complex the situation is so thank you for following along the developments well check back with you later on. Despite what were hearing from nic about the diplomacy at play while theyre talking, the fight something raging on in Eastern Ukraine. We have Nick Paton Walsh live from the battle zone near the town of donetsk. We have a bit of a confusing situation for many of the separatist militants here. While they only heard of the ceasefire deal from us their reaction is weve been deceived before were not buying this. We dont stop until weve taken back the rest of the donetsk region. These men arent commanders they could be told to lay down their weapons. But weve been hearing the sounds of rockets being fired, the sounds of rockets landing. Theres no obvious sign of tempo. Its the reaction youve seen in the faces of the men on the front line. Behind me is a reason why theres so angry, the damage done civilian areas here basically you can see in their faces, their anger, the loathing they feel towards the Ukrainian Government they said the shelling has done to their homes and families. And a real sense here i think that this diplomatic explanation is going to have to be substantial and remarkable i think when they first hear it in detail to make them want to lay down their arms a very clear sensation that they want to fight on. Ailsen . Such a perfect illustration of the confusion that continues on the ground there, thank you. Well check back in with you. President obama formally asking congress to authorize military action against isis. But his request is already drawing skepticism from both sides of the aisle. Lets check in with White House CorrespondentMichelle Kosinski with the key points of that proposal. Its basically the president asking congress how much should i be able to do or not in fighting isis . This balance between narrowly tailoring it but also leaving flexibility as things change down the road. And you do see a balance. I mean really the only big restriction in this is against enduring offensive Ground Combat operations. Or as the president put it longterm largescale operations like what we saw in iraq and afghanistan. But how long is enduring . What does that mean exactly . Obviously there is room for interpretation there. And theres nothing in this that would restrict say shortterm smallerscale combat and it allows the 2001 authorization against al qaeda and its affiliates stand. It lets the president fight isis wherever it is along with allied groups fighting alongside. And it allows for other combat like special operations search and rescue calling in airstrikes some of which weve already seen. There are some democrats who would love to see this more restrictive. Some republicans who would love to see it less restrictive. Its up to them to ray prove it or not or come up with their own. Chris . Michelle thank you very much. Mick over to you. In the war authorization request, president obama names the american who is have been killed in isis captivity. Including aid worker Kayla Mueller. Were learning more about her time as a hostage and some of the various attempts to rescue her. Pamela brown is following these developments live. Some comfort to many that those attempts were indeed made. I spoke to the family spokesperson michaela about this. And she made it clear the family did everything it can, working with the white house, trying to get kayla home. In fact at one point last summer when isis issued a deadline to execute kayla, the family asked if the government would be willing to trade dr. En sadiki. After hearing about this in media reports, the family asked the white house if it could have the lady al qaedas sentence commuted. Trying to find any option they could, in desperation as the deadline was approaching, the execution deadline. We know what the white house responded back we dont know what the response was. But the spokeswoman said that kayla was still alive after the deadline passed. Contrary to media reports, the family never turned down a military rescue mission because it was too risky. Instead the family reached out to the white house to ask for notification if there would be another rescue attempt after the failed attempt of kayla. Weve been hearing about the attempts to rescue her. And one of them is about a man who posed as kaylas husband and went to a syrian terrorist Training Camp to try to save her. It turns out that was her boyfriend who was kidnapped with kayla, the same time. He was later released and then risked his life to try to get kayla out of captivity. That did not happen. But its clear, chris, that many efforts were made along the way. Pamela thank you very much. Appreciate it. Lets get more on the president s war plan to fight isis whats going on in ukraine. We have a man who understands both situations cnn military analyst, Major General james spider marks. Thank you very much for joining us. Lets start with the immediate. In ukraine, at least they have a timeline now, right . Last time in minsk it wasnt that clear. But when you look at whats being said out of there, does this feel like a real ceasefire . You know it does i thought that what nic was reporting on the ground he has as you guys know and cnn has done a wonderful job, hes putting himself at risk so we can get the best view of whats taking place. At that lowest level, thats where the difficulty occurs. I mean a ceasefire like this could be broken in a second. If those fighting parties, those warring parties simply have make a bad decision at that very very very point of engagement. But it feels like theres going to be some progress. Certainly theres a very special relationship between Angela Merkel and putin. They understand the risks involved and its wonderful that theyve been able to at least get together and have an initial framework of how this thing needs to move forward. Interesting, given the strained history of germany and russia. Now when you talk about the ground you understand this so well from your time as a commander with the balkan situation. The vebls s rebels werent at the table in name with these diplomatic relationships. Putin was there. If they keep fighting whats the use of this ceasefire . Well what putin has to be able to do. And clearly, lets establish right now that the insurgents that are fighting in ukraine right now are getting direct support from the russians. End of sentence period. So what putin has to be able to do is if he is sincere about this he has to withdraw his advisers. He has forces that have gone across the border those have to be withdrawn. Can he do that surreptitiously, he can do it overtly. He has to assert himself very directly over this in order for this to end. The only way theyve been able to act with a certain degree of independence and achieving the successes they have on the ground is because of putin. He needs to withdraw that support and this thing will peter out. The way to do it would be International Monitoring of that and he wont agree do that. Kayla mueller, the accusation is the u. S. Government didnt do enough. This time that doesnt seem to be the case. We hear a lot of rescue attempts what stands out to you . The fact that the United States truly embraces its citizens wherever they are and will do anything it can to try to get them back. I think that, that discussion piece, this is such a tragic and such a personal story. Were very sensitive to it we have to put to the side the fact that the United States may or may not or intentionally ties its hands in its abilities to try to recover its citizens. This is the United States does everything it can. It puts incredible young men and women at risk to go rescue these folks, lets put that story aside and lets take the bigger story which is how can we more fulsomely go after guys like isis. The reality, Kayla Mueller, on one part represents the absolute best hope for the future. Kid who put her own life in the hands of people she just thought deserved her help. But the president said we did everything we could its about how you define could. You didnt want to do the prisoner exchange. You dont want to negotiate unless its somebody who is in the military and Kayla Mueller represents the future nonmilitary people going into harms way to try to make a swigs situation better she may represent a better option than military action in fighting ideas like isis. Is it time to rethink the policy . We have the full elements of power in place, with the collapse of governance in the middle east and other places around the world, the United States backing up from its position of influence around the world, you have to have industry step in you have to have ngos, nongovernmental organizations, folks like kayla that get involved and fill in the gap where the government has said were not going to do it. So yes, theres an absolute time to relook how we view these types of contributions. Also now on the aumf the authorization for the use of military force, you know that. But now you see whats out there. The democrats say its too broad, the respects say its too narrow. With what you hear in whats being offered, do you think this is the right type of approach . Yes. Yes. It does repeal 2001. So it gives the president still has very very broad authorities. Whether he chooses to use those, under that remain in place. But the new one says look weve got a problem that is metastasized, in 2001 we didnt know what it looked like. We have a pretty good sight picture on what this enemy looks like where its located. How its getting its motivation. How it recruits how it deploys and we described geographically kind of where it is. We need to be able to define that very precisely. And as michelle indicated, the word enduring leaves the door open for interpretation in terms of what does that really mean. The president has very broad latitude and its good that he hasnt taken a capability off the table. Weve got the most incredible military in the world, why would you state our priority were not going to use the air force or use a little bit of the army dudes. No it gives him full authorization. Its interesting its being called a war authorization. Colloquially by these guys even though congress theyre the ones who have the power to declare war. This is another step in the direction of giving that power to the president. General, thanks as always. Thousands of people taking to the streets in yemen to protest the houthi militia takeover crowds are gathering in the capital, sanaa, carrying banners, chanting anti houthi slogans, while houthi fighters man checkpoints.

Weve lost a man who was a stellar example of humanity and journalism. Cbss bob simon was killed overnight in a car accident just blocks from his home. An end that stands in stark contrast to the peril that simon overcam in being one of the best newsmen. Our 60 minutes colleague bob simon was killed this evening. It was a car accident in new york city. Cbs news anchor scott pelley reports a shocking end for a man who had survived so much. Distinguishing cbs, 60 minutes, and enlightening the world for over 50 years. Our colleague bob seemens of 60 minutes was 73 years old. Joining cbs in 1967 simons words quickly separated him. You guess it must be safer. As did his commitment to covering turbulent times, especially abroad. And steps are being wheeled up to a plane bearing the words, the arab republic of egypt. In vietnam he was on one of the last helicopters out of vietnam, then came yugoslavia and the gulf war. In 1991 he was captured by iraqi forces imprisoned for 40 days. They didnt feed us at these interrogations they terrorized us. After youve been beaten a couple of times, its extremely unpleasant and it hurts like hell but after a while it stops. His spirit and talent endures, as will his legacy. Bob simon represented the best of journalism. May he rest in peace. Indeed. Thats sad i always loved watching him on 60 minutes, he had such a great voice and presence and storytelling, after being in the most dangerous battle zones of the world who knew that a livery cab in new york city would be where he would find his ultimate demise. Survived by a wife and a daughter and its interesting at a time when were examining journalism this is a guy who is proof of how the job is supposed to be done. Yes, he had the telegenic qualities, but he put himself in hard situations so you would understand them better for 50 years. Our best to his family and to the cbs family as well.
