let's just assume that the agent was sarin, for example. so sarin, it evaporates rather quickly. you had mentioned that before. there had been a discussion that i thought was very interesting. but then also it does linger in soil, depending on whether it's in an acidic environment. there are reports that lasting up to 22 weeks, in some cases possibly two years, but it's highly doubtful. you have to know where to go after a certain point in time, after a few days really to get confirmation that the degradation components, what sarin dissolves into, are present. you can do it, and this is an interesting case because before when the inspectors were coming in, they were going to be looking at three areas that had experienced alleged sarin attacks in december of 2012 and then back in february so very doubtful they would find those degradation components. now if by some miracle they were able to get into the area even today, they could find actual fresh sarin. they could not even the degraded type. you do have to act fairly quickly. if you don't, then you have to be a better sleuth at

blind eye to its use of chemical weapons including sarin gas what happened here is that. you were i was about to win the war and the satellite photography showed that there was a hole in the iraqi lines and so we were we told the rockies where the hole was what the rings were preparing. do. enter sarin gas and tens of thousands of iranian troops were killed now in the broader context if i were in iranian and i just heard that the the duly elected government of fifty three had been deposed by the cia in fifty three and then i saw in eighty seven that we we're rain ians we're just about to win the war when this happened you know i would feel really really strongly that we have. real grievances against the united states and their mission it now is because we have a new government in iran and it's going to be very hard for them to tamp down this this hatred you know this resentment when you have the rebels the revolutionary guards and all those other people saying how can you trust the americans in fifty three they were through our government eighty seven they prevented us fr

he is pointing to sarin gas that could have brought in to syria.hat was the contention of the ambassador. we'll have to try to figure out what happens through these un inspections when they are completed. we heard earlier today that bankky moon said it will take four days to complete the inspecti inspections. we don't know if that is four days from now, or if we are on the second of the four. it will be very interesting to find out the time frame is critical, so we'll want to know exactly which way that -- that issing pointing, but again, in terms of what is coming from the syrian ambassador, that -- i suppose there are people who would say that is going to muddy the water to a certain extent in terms of what these findings may lead to, but everything is going to have to go with what the united nations determines. the united states doesn't seem to think there is any question whatsoever as to who's chemical weapons those were. >> there are reports coming out of that area that are also contrary to what the ambassador said. >> there have not been find

see on pictures doesn't seem likely to be the weapon secondly if it is a poor low grade version of sarin then probably it's not made by the syrian government is functioning in peace and security until very recently but possibly by people using. the elements that you find in cheek dick in in various insecticides used on us which contain some of the precursors for sorry that after all is how nazi scientists invented sarin in the first place they were making a insect pesticide and then discovered that they had found something very good which could be used on people so we don't know exactly what the weapon is and unfortunately because of where it's been used we can't really certain who. might have used it because we there's no independent observation at the scene of the incident life from oxford in the u.k. thank you very much indeed. had this. contract means zero guarantees over a million brits face being left penniless despite having. the economic crisis and excuse to employ people with no promise of payment other stories after this break. wealthy british. market. find out what's really ha

is is a possibility in future and you know all world nations want to guard against the thought of sarin of on an airliner or in a big city like moscow or london is absolutely horrific and very difficult to guard against which i think why it's imperative that that the world acts now first of all in response to this massacre last week but also to prevent proliferation out of syria and spreading the chemical menace further than the borders of syria itself you said again trying to pin down who did this you said in an interview before the evidence about the delivery of gas could point to who is behind the attack isn't in there. well i think first of all this appeared to be a very well planned attack pretty bombardment of conventional weapons to destroy windows and doors and then the bombardment of chemical weapons. this was a sophisticated bombardment of the scale of a larger at nine hundred eighty eight so that gassed the kurds and killed five thousand in one day and subsequently tell thousand died this is not a little bit of sarin or nerve agent that's been used this is a large amount that

so it's not -- there are some types and mixtures in which sarin is used where you wouldn't quite haveuch contamination. there are going to be some technical issues that come up and what has been released by the white house on the intel, the 4-page document is a summary of intelligence, not the hard facts underneath that intelligence. so, for instance, we don't have the autopsy reports of the people who have been killed to show that she had sarin or other nerve agents in their bodies. we don't have toxicology reports of the people who will have died. i think that what is going to happen over the next few weeks is that nell probably go through another round of this discussion on the intelligence. by the way, after iraq, where we had no wmd after the bush administration swore up and down there was, this is actually a healthy debate to have. and it's one that's worthwhile. so as we go forward, there may be some surprises in the intelligence. we just have to see. >> what do you think of the warning of russia and iran that a would have a catastrophic repercussion >> that sounds like a warni

>> let's say sarin and vx first. sarin we've talked about -- we're talked about it lately.x is very similar. they're both nerve gases. they are highly fatal. they can kill within minutes if you get a high enough dose. >> within minutes. >> within minutes. so it causes first your pupils go down to a little pinpoint. nausea, vomiting, paralysis and finally death. mustard gas is a little bit different. mustard gas usually is not fatal. but what it does is it causes blisters on your skin, your mouth, sort of all the way down into your lungs. and it can cause cancer later in life. it can also cause blindness. so it's a little bit different, but all of them, you know, extremely destructive and horrible. >> we heard from the secretary of state saying it is this chemical weapon stockpile, it's the largest in all of the middle east. we're talking, just to make sure everyone's straight, there is the -- there is this government assessment, this intel report on this attack on august 21st. we just heard from arwa damon talking about a separate attack this past monday. we saw these pictu

here are the symptoms of sarin gas listed out on a tweet. example, hypo salivation is mentioned there. you don't necessarily see that in these photos exist that is a pretty specific symptom. others on social media are saying the symptoms such as dilated pupils him to be more symptomatic of other infections. >> giving a diagnosis looking at photos that may or may not be authenticated. >> just in a couple of other images doing the rounds of social need you. this is what a syrian artist did, a gas mask with a a b asset fire the conclusion there that children are being killed due to chemical weapons. the official news agency has obviously denied the use of toxic gases in damascus completely. interesting to look at the newly unveiled instagram account of bashar al-assad. this was unveiled at the end of july. this is to try to respond to the anti-assad messages coming through. in any case, worth pointing out that there has been complete silence on the instagram account today. the last post was on the 19th of august. why have they not put up contra

where syrian soldiers came under fire to quote the letter and said with poison close to a nerve gas sarin and it was that same gas that was used in this attack last week the u.n. inspectors say that they'll conclude their mission by in next monday they are talking to eyewitnesses they are gathering samples but the problem is that the only conclusion they'll be able to give is whether or not a chemical attack took place they will not be able to give any kind of indication of who was behind it such attack and increasingly we're hearing from all political forces that there needs to be a united nations mandate before they can be any kind of western military action we're hearing this from the u.n. peace envoy brahimi at the same time russia saying that it is against any kind of military action inside syria russia saying that the united states is jumping the gun and that there needs to first be a u.n. mandate and the findings of this u.n. investigating team before any conclusions can be drawn as to whether or not a an attack carried out was carried out using chemical weaponry and b. who was beh

said her evidence that rebel fighters are the ones that may have used nerve agent the nerve agent sarin in syria and that it was not used by the syrian government. our investigators have been in syria and in neighboring countries interview victims doctors and food hospitals and in the latest reports we got last week i saw that although there is still no incontrovertibly prove there are very strong suspicions judging by the kind of medical help the victims received the sarin gas has been used by the opposition rebels and not the country's authority but it's not surprising because militants and people from outside have already infiltrated the opposition. and of course that was. from may we don't know how much worse the situation may have gotten in syria now as of today russia's foreign minister sergei lavrov said that russia wants a fair investigation and has denied reports that moscow blocked any type of u.n. security council statement on wednesday when the council gathered together to discuss the use of the alleged use of chemical weapons in syria in the meantime france is reportedly ur

played a role in helping saddam hussein use that sarin gas to defeat iranian troops back in one nine hundred eighty eight here's how according to declassified cia documents that were discovered in the national archives in maryland using a satellite images u.s. intelligence officials conveyed to blow the location of iranian troops to iraq fully aware that hassan hussein's military would attack with chemical weapons including sarin a lethal nerve agent and it gets worse according to those same declassified cia documents a senior u.s. and fish bowls say they were being regularly informed about the scale of the nerve gas attacks they are tantamount to an official american admission of complicity in some of the most gruesome chemical weapons attacks ever launched i was joined earlier by jamal avi he's a policy director at the national iranian american council and i asked him how shocking these revelations are and whether or not iranian suspected this before there was a pretty widespread perception that. you know the u.s. was to be involved in coordinating with iraq in supporting saddam in

: victims can die within ten minutes of breathing sarin gas.can be fatal. even contaminated clothes can hurt you. iraq used sarin against the kurdish people in the 1980s, killing thousands. the japanese cult used sarin in terrorist attacks in the mid-'90s. the people treating these victims don't have any sort of respirators or protection on. why aren't they getting infected as well? >> there's been an attempt to wet these people down and decontaminate them. that's what decontamination in a rush is all about. to make sure they're at least doused with water, if not soapy water, and the clothes are taken off. >> reporter: nerve agents like sarin blind victims, causing them to choke and spasm. >> like this. see the twitching in the body? >> reporter: and these images of the dead show no sign of a conventional bomb blast. >> there you see bloody bodies, broken bones, and gaping wounds. >> and obviously we did not see this in this attack in syria. now, some people do survive these kind of attacks. there are certain drugs that can help counteract the

it will tell you if it's sarin or others and will test for mustard gas.t seems that the most logical explanation was that a nerve agent was used and probably sarin. we have a very simple device here that works with antibodies, and will identify up to eight toxins or pathogens like anthrax, ricin, and this is a quick test that could be done in the area. you'll get an answer in a few minutes. we start off with an one size fits off respirator that can be put on in a few seconds. this will give you comprehensive protection against even the strongest chemical weapons for some period. i think allied with that is basic advise, ideally you should move upward because the gas will be moving rapidly downwind, and you should move to high ground. these coming clouds, hold your breath for 20 or 30 seconds and get through that cloud, and there is a strong chance that you'll survive. the planning that went into this attack seems to be some detail. a pre-conventional bombardment to blow the windows and doors out so the chemicals much more easily get in the buildings. then

sarin is an odorless, colorless and tasteless liquid that can kill in just a few minutes.also odorless and tasteless, causes muscles to contract just uncontrollably. and finally, mustard gas. it was known for its devastating consequences during world war 1 and causes blistering of the skin. it smells like garlic, onions or mustard, therefore its name. they can all be deployed in a variety of ways, from the land or air. u.n. weapons experts have reportedly recovered a rocket fragment from an area that was attacked earlier and it appears to come from a short-range artillery rocket and that is commonly used by syria's army. so hopefully that answers some questions for you. gretchen, peter, and eric, back to you. we'll keep on this one for you. >> gretchen: scary answers. thanks very much. coming up, many democrats and republicans agree the president's economic advisor, is he doing a good job? i guess so. why is he about to call it quits? charlie gasparino says valerie jarrett is to blame. >> eric: we showed you a video. a woman gets hauled on stage to sing a duet with kristen

they were saying that they do believe that they are sarin gas. the u.n.'y who used chemical weapons, but if they were used. that earlier report that i was just talking about did cause the u.s. to ever so slightly shift its policy towards syria. talking about sending in some weapons. but nothing that has significantly changed the dynamics on the battlefield. so again, we're going to have to wait and see how the white house decides to react to this most latest attack. hundreds of people killed among them, many, many children. >> arwa damon reporting live from beirut. thank you. >>> egypt this morning is quiet, a far cry of how it looked a week ago, after sparked days of violence up to 1,000 dead. the u.s. is pulling back on claims it may have cut off some aid to the country. that, as the court is now set to review the detention of former leader hosni mubarak. his lawyers want him freed on bond as he awaits charges that he was complicent on the killing. >>> now the beaver creek wildfire was reached about 30% containments hundreds were allowed back in their ho

children were affected by this sarin nerve gas. in your judgment, is there enough evidence for the united states to take military action? >> well, hopefully they've got intelligence on this, hopefully on intercept on people firing things. hopefully they've had sources carry out samples. there's a base of sources that they have to have on the ground. there are forecountries with people on the ground there. it's hard for me to believe they wouldn't find some evidence. i understand general mccaffery's point, you want to make sure, first off, they were fired and it's clear who fired them. they should be able to see from, you know, what locations those rockets were fired, there is got to be technical coverage having gone on out there. that should be available. >> john mccaffery, i'm going to come back to you on this point. let me assume that the united states will follow through as john kerry mentioned, it looks like the president is determined. general mccaffery, these missiles, can they take out government buildings? can they take out
