Area yesterday. Nerves are still frays after dozens of aftershocks still rocked the area today. More than 200 people were injured and dozens of buildings are damaged to the point where they are now off limits. Dance i dan simon is in napa for us. Give us a sense of the scope of the damage. Every building on this one block where im standing has been red tagged. Meaning they are uninhabitable. This is an example of the kinds of things were seeing. You can see, absolutely crumbled. You see all the bricks on the ground. At the bottom, you had an outdoor cafe. At the top, you had offices. What folks are doing now, what crews are doing now, theyre basically assessing the damage, trying to make sure there are no more gas leaks. Trying to make sure there are no water leaks. What we saw earlier today is that crews basically did a great job in restoring the power. Now, its working out some of the other infrastructure problems that you had. You have some roads that are buckled. Thats why so many streets throughout have been blocked off. You really cant get through. Theres a sense that things are turning to normal. Some of the public buses are running. Some of the businesses are starting to open. Its going to be a long time before things truly return back to normal here in napa. Wolf. Any assessment to the damage of the economy of this area . This after all is the heart of wine country. Its a huge Tourist Destination as well. Theres a huge concern that this is going to have a major impact on the local economy. Especially the wine industry. This is a 13 billion industry here in napa. Youve seen these pictures of barrels being toppled over. Of the wine bottles toppled over, broken. The wineries are still assessing the damage. There is broad concern that there are going to be some steep losses, wolf. Dan simon in napa for us. Five days after the release of the video showing the execution of james foley, another american was released. Peter curtis was held by a Different Group than foley. Our Nick Paton Walsh has more. Reporter it is interesting that this particular group chose to release peter curtis right now. They are affiliated with al qaeda. They are described as a terrorist organization. They are at times rival, to isis who are now the target of u. S. Air strikes. Some speculating that perhaps they assisted mr. Curtis in his release because they wanted to score some good pr opponents in the eyes of the west. After a week of horror, finally some good news. An american held hostage in syria by islamist rebels for nearly two years is free. 45yearold peter fior curtis, a freelance journalist, released sunday after being held by the al nusra front, a Syrian Rebel Group with ties to al qaeda. His family thanking the governments of u. S. And qatar for their efforts. While the u. S. Has denied any involvement and details about his release remains unclear. Curtis was handed over to United Nations peacekeepers in the Golan Heights who then released him to u. S. Government officials. My name is peter reporter these videos show curtis during his last few months in captivity. In this video, a rebel points a gun at his head while curtis speaks rapidly as if under duress. Curtis was captured near the syrian turkey border in october 2012 and held in aleppo with american journalist matthew sh rhea. The two locked up for months before planning their escape. Shria breaking free through a window with curtis help. Curtis, however, got stuck trying to escape. Im pulling him and im pulling him as hard as i could. We were not making any headway and we were making too much noise and the windows were open and the lights were above me and the sun was coming up. You must have known then that you had to leave him . Yeah. Yeah, it was one of the hardest things ive ever had to do. Im not going to have closure until hes home. Reporter curtis release comes just five days after isis released a video of one of its militants beheading american journalist james foley. On sunday, his parents releasing a letter on facebook, that they say he composed in captivity. He talked about sharing one cell with 17 others and playing games made up of scraps they found. Foley had a fellow hostage memorize the letter, dictating it to his family upon release. British officials close to identifying the isis militant responsible for the beheading. Expert, say he spokes with a distinctly british accent. Investigators making headway, using clues in the video to pinpoint the killer out of hundreds of british muslims who had joined isis. We were putting out a great deal of resource into identifying this person. I think were not far away from that. Reporter peter Curtis Family are clear, they dont believe money changed hands in this release. They dont know the full details. They say this was a humanitarian effort. And that was the principal guiding factor behind his release. Very many details, though, still to clarify, but one American Family extraordinarily happy. Nick paton walsh reporting for us, thank you. Isis fighters have captured more territory, this time in syria. The insurgents cea s seized a my base in the north. It effectively gives insurgents control of the raqqah province. The Syrian Government saying its willing to accept support from u. S. And others in its fight against isis. President obama considering taking military action to stop the surge of isis terrorists there. Air strikes have slowed the Extremist Group from advancing in neighboring iraq but isis is thriving right now in the chaos of syria. Cnns Barbara Starr is joining us from the pentagon. Barbara, the president is sounding serious about possible air strikes. What kind of pressure is he under to move in that direction, not only launching air strikings in iraq but expanding to air strikes in syria . By all accounts, the president has yet to make a decision to give the go ahead for it. But some initial steps could be under way. What officials are telling us is before they would even do air strikes, they will have to fly reconnaissance flights into Northern Syria over this raqqah stronghold of isis. They need to get a very closeup look at the ground. Where are the isis troops. Where are the command and control centers, the training camps, the installations. That would be the targets that they want to go after, again, to sort of stop isis momentum across this wide swath of Northern Syria. To deny them this safe haven. Nobody thinks air strikes are going to put isis out of business, but they have seen, they say, some evidence in iraq that its working, that its putting them on the run a bit, that theyre not as free to move around, that they cant just simply sweep into towns anymore, so theyre hopeful if they get the go ahead, they can do something similar in syria. Still, make no mistake, its a very long road. One of the questions, would the u. S. Coordinate any of this with the Syrian Regime. Right now, indications are the u. S. Military would not coordinate with the assl acissa regime but if it got started this could go on for months. The u. S. Does coordinate air strikes in iraq with the Iraqi Military as well as the Kurdish Peshmerga fighters. In syria, theres a free syrian army, as its called. But its rather limited in its capabilities. The u. S. , if it doesnt want to coordinate with Bashar Al Assads military, its going to have a problem in syria, right . Well, it may get a bit difficult for the u. S. Military. I mean, look, assads forces have been fighting for the last several days to try and hold on to that air base you were just talking about that isis, by all accounts, has now taken. You know, in this area of Northern Syria that is now essentially the isis safe haven, how much influence syrian forces, assads regime, have here really part of the intelligence question. Right now, all the indications are isis has a pretty good grip on this area. If the u. S. Can get in and out with its aircraft, with a minimal risk of encountering the syrians or being shot down by them, it may be a risk that military planners are willing to take. One of the things we continue to hear is that this area of Northern Syria may not have the level of air defenses that you see the Syrian Regime maintain further south around baghdad pardon me, around damascus and other key areas. The Syrian Air Defense is very well built up over the years, also along the coastline, because they feared an israeli incursion, if you will. So this area in the north may be something that the u. S. Can deal with without coordinating directly with the syrians. If you start air strikes, they could go on for months to have any meaningful impact. So well see if not coordinating with the assad regime to something they can stick to. Well see what the president decides to do. Barbara, thank you. Lets get some more now on the funeral of Michael Brown, the 18yearold whose death touched off protests and marches. Jake, give us a little sense of the message were hearing from browns Funeral Service today, after days of angry protests. Is there a sense of hope coming from the service . Well, wolf, i think its fair to say, apart from all the cameras and the celebrities, this is clearly a time of personal grief for Michael Browns family. And one of the things thats been so important about the service is how much meaning those speaking have been trying to find in his death. About what his death has spoken for. About who has been moved by this and about the fact that for many people Michael Browns death is about a larger issue, about a larger movement, and thats the hope that im getting from people speaking here, that the idea that something more meaningful can come from this dialogue or perhaps more. Wolf. Is there a sense that the folks there will honor the desire by the family that they avoid protest marches at least on this memorial day . Well, you can hear right now, wolf, people coming out of the overflow, chanting hands up, dont shoot, hands up. This is an the scene going on right now, young men, yelling, hands up, dont shoot. And a woman saying, i love you, but dont come out here and protest, dont come out here with this. They have since quieted down. Obviously, there is an effort to quell and quiet any of those passions, at least right here in the immediate vicinity of the funeral, wolf. Im sure the brown family is pleased that three officials from the white house had decided to attend this Funeral Service, right . Im sure they are. There are a lot of Public Officials here, i should point out that those who are affiliated with officer Darren Wilson feel like the presence of a white house delegation, the presence of other Public Officials here, is unfair, because obviously officer wilson has his side of the story. We have yet to hear what it is. From what weve heard from the police, they maintain that he was attacked by Michael Brown, and the idea that there are white house there is a white house delegation here, there are Public Officials here, to those affiliated with officer wilson, and of course he has the presumption of innocence just like anyone else. They feel like that is the government weighing in and saying, well, we believe this version of events, we dont believe officer wilsons version of events. Its a very sensitive time. People who are coming to the funeral are trying to say this is about the loss of an 18yearold, this is about one familys personal loss. But there is so much politics and protests surrounding it, there are those who take issue with the white house delegations presence, as well as the presence of other Public Officials, wolf. Well be checking back with you, jake, throughout the day. Jake will be anchoring the lead, 4 00 p. M. Eastern, from st. Louis, ferguson, area. Much more coming up on the lead. Jake, thanks very much.

Im talking about the man who executed the american journalist james foley and whose british accent may be the clue to who he really is. Brian what do we know about this man . Were learning the search for his identity is intense. The forensic investigation into that video, to be able to name who that man is, is very intense. Asked by our own Candy Crowley as to whether they have the name of the person would did this, the British Ambassador to the u. S. Said were close. It doesnt mean we know if theyre that close to getting the name, or are they close to being able to tell us who the name is. Do the british know the name and theyre not able to tell us yet who it is . We do know were close to having a name of somebody to be revealed later this week. We do know from our conversations excuse me with british officials, that theyre going over every piece of this video. The voice on it of course is key. The background. The terrain where they were. Theyre looking at the editing of the video because the video does go black during the apparent moment when hes being killed. Those are all the forensic things were looking at in this video. Of course were told theyre close to being able to say the name of this person. Do we know how many british citizens are part of isis in iraq and syria now . Our conversations with intelligence officials here in the United States indicates there ahundreds of british citizen, somewhere between 400 and 500 british citizens who have gone to fight in syria and within them, hundreds are members of isis. Theres a strong british contingent of fighters within isis. Americans, only a handful. British, french and german, they number in the hundreds, those numbers in isis it the scary thing is of course wolf weve all been reporting they all have western passports, they dont necessarily need a visa to get back in the United States, so they can travel here fairly easily and thats what u. S. Officials, you can sense their concern over this is ratcheting up. The British Ambassador says theyre close. Well see how close they are to identifying this individual. Thanks very much for that report. In the days leading up to the killing of the journalist james foley, isis made two demands. Before the terrorists demanded a 132 million ransom, they offered a prisoner swap. In exchange for foley, they want a woman released whos serving 86 years in a texas prison. Jean casarez introduces us to the woman known as lady al qaeda. What im saying is simply that a woman is not an unpaid slave. Reporter this is dr. Sadiki, also called lady al qaeda, a pakistani national, her release from a u. S. Prison was one of the demands made by isis in exchange for american journalist james foley before he was beheaded by his captors. In an email sent to foleys family on august 12th, isis wrote, we have also offered prisoner exchanges to free the muslims currently in your detention like our sister dr. Afia sidiqqi. She is an icon, she is the poster girl for jihad. And in that way, she served as a sort of rallying point. She is the premier symbol of the muslim woman in distress. Reporter sadiqqi earned degrees from mit and bran dies university outside boston. This petite 44yearold woman, a neuro scientist and mother of three, lived in the u. S. For more than a decade, and in 2003, she disappeared. In 2004, was put on an fbi alert list, considered a clear and present danger. In 2008, sadiqqi was stopped by Afghanistan National police for acting suspicion outside a government building. According to court documents, officers searched her handbag and found numerous documents describing the creation of explosives, chemical weapons and other weapons involving biological material and radiological agents. Handwritten notes by sadiqqi referred to a mass casualty attack. Listing various locations in the United States, including the empire state building, wall street and the brooklyn bridge. When american authorities came to question her the next day, she grabbed one of their rifles and started shooting. Sadiqqi was flown to the u. S. Where she was never charged with terrorism but convicted of attempted murder. Sadiqqi claimed she was framed. She interreupted her trial repeatedly with heated outbursts, antisemitic outbursts about jews, all kinds of things. The judge found she was mentally capable of standing trial, but that she needed some sort of treatment and thats why he sentenced her to a prison in texas where she is able to receive psychiatric care. Reporter she has a notorious inlaw. She married the nephew of Khalid Shaikh mohammed, the mastermind behind the 9 11 attackings. Basically, is she a scientist or a terrorist . Shes definitely a terro
