on what was obviously a challenging mission. >> reporter: director clapper is james clap he should the u.s.' director the national intelligence, in a statement the u.s. state department called clapper key to the men's release. we are grateful director of national intelligence clapper who engaged on behalf of the united states in discussions with dprk authorities about the release of two citizens. it's not clear why clapper was brought in to negotiator whether he had a second reason for meeting with officials in pyongyang, the north koreans reportedly prefer to negotiate with either former presidents or high-profile diplomats on the fate of u.s. citizens. there is some speculation by releasing the men kim i don't think un might be trying to soften his country's image. north korea still fashions sanctions bus it refuses to stop its nuclear weapons program and the u.n. security council should soon refer kim and other officials to the international

criminal court for human rights violations, neither b avenue. nor miller will be prosecute today travel to go north korea you can but the obama administration is warning other americans it's not a good idea to visit. victoria, al jazerra. >> speaking to robert kelly joining us via skype from south korea he's a professor of the political science of diplomacy. you know the americans coming out and saying no concessions off erred to north korea. that's on the public face. privately could anything have been given to them? >> yeah, well, in the past the north koreans have been pretty canny negotiators they usually ask for some quid pro quo which the northwest wants something out of north korea. if i was the north koreans i would be asking for three things, one, some kind of relief on the sanctions since north korea has engaged in the nuclear tests and missile tests the

sanctions have gotten tighter i would ask for relief on the banking industry, the north koreans keep a lot of money offshore and places like hong kong and it's made it harder and harder for the north korean elite to import luxury goods if i were the north koreans i would be pushing for that. america probably didn't give any formal but maybe they are looking away. it's hard to believe they gave them away for nothing. unless they are looking for a major breakthrough with the americans we don't know that they haven't said anything to that effect yet. >> what about this human rights report that the united states wants to refer north korea to the i.c.c. how much could have that weighed in the north korean's decision to release the men? >> yeah, that's sort of the third thing i was going to mention there. that's actually increasingly become a big deal to the north koreans they have began giving speeches in press conferences in in new york in theup, which is

unprecedented we have never had north korean officials go on saying they don't have labor camps they are reeducation camps for people that love our dear leader. that they have are they are even admitting these things tells us that they might be worried and trying to get the americans to hold off for six months or a year to relook at the resolution on this. something like that. again, we just don't know. but we know that the north koreankoreans are more scared at this in a while. they have never used to talk about this stuff and now they are. >> negotiations, robert, obviously very second five, done behind closed doors, but what's interesting, the involvement of clapper himself in this. >> yeah, that's actually kind of a new one. in the past the north koreans have milked these arrests of americans for a big high-profile visit from a former president or high up official. this is pretty important for the north korean when they stand next to an american president or something and tells the north korean people that it's a real country and important the americans take it seriously and

stuff like that. obviously president "real money" president obama will for the go. staff can't go. last people thought maybe mill are you clinton might go or something like that. i remember meme saying that. clapper went that's odd, he's an intelligence person. we'll see if there is ideal going in the background as your correspondent mentioned. >> okay, robert, thank you, robert kelly joining us from south korea. u.s. air strikes have hit a gathering of fighters from thize lamb i can state of iraq and the lolevants a u.s. military spokesman says the strikes hit a convoy of 10 vehicles thought to be carrying senior members of isil near the border crossing between iraq and syria. officials say they can't confirm if the isil leader was part of the convoy. he made a rare public appearance in july which he gave a sermon in mosul. now a leaked report from pakistan says that isil has recruited thousands of fighters
