hillary clinton visits pakistan, but is she building bridges? and picking up. survivors of the u.s. tornadoes return home alive, but they're mourning the loss of friends. he evaded justice for more than 15 years, but time is up for ratko mladic. the former chief of the bosnian-serb army is due to be back in court in belgrade today for a hearing that could see him handed over to the international war crimes tribunal in the hague. he's facing charges of genocide and crimes against humanity committed during the war in bosnia between 1992 and 1995. from that time to this, the international community's demanded that serbia find mladic and hand him over to stand trial. he's now 69 years old. mladic, seen here on the right in a cap, was led into a courtroom yesterday, but proceedings were cut short because his lawyers said he wasn't well enough to speak. serbia's president is confident he'll be extradited to the hague within seven days. once there, he'll be allowed to enter a plea to the charges against him. mladic was captured on thursday in a village in the northeast of serbia. the president says the wanted man's relatives have been hiding him, but an investigation is now under way to find out who exactly knew that he was there. let's get more now from our correspondent from the former yugoslavia, ivan watson in belgrade, fred is in bosnia herzegovina where there's a mass grave memorial. let's start with ivan first. is he going to be well enough to stand trial? the doctors are taking another look at him today, right? >> reporter: according to his defense attorney, that's what he tells cnn, that mladic does need to be examined to see if he's fit to stand before a judge. the man is described as europe's most-wanted criminal is currently in this courthouse right now. that's where he was kept overnight. and the news of his arrest really has been shocking for serbia. his face on the front page of all of the local newspapers, showing him before in the '90s at the height of his power when he commanded the yugoslav army and committed the alleged war crimes and then after, looking like a shadow of the former military commander. thinner and apparently frailer as well. on the front page of the tabloids as well. his defense attorneys, zain, describing him today as a ruin of the, quote, once monumental of personality that he knew ten years ago, saying that he has suffered numerous strokes and heart attacks and is not fit for trial right now. that, of course, is up to the doctors to determine. we've seen ratko mladic's wife and his son enter and leave the courthouse several times throughout the day today. they have not spoken to journalists when they have gone in and out. serbia watching very closely what will happen here. and the serbian president telling cnn last night that he expects ratko mladic to be extradited to the hague within seven days. zain? >> ivan watson in belgrade. fred joins us now. fred, what have people been telling you? >> reporter: well, zain, i mean, a lot of the people we've been speaking to obviously say they're very happy and very relieved that mladic has finally been brought to justice. however, there are also people who say it took a very long time. so far justice, of course, has not been served. some say quite frankly they believe what you see around me is mladic's legacy. this is the place where about 8,000 muslim boys and men were slaughtered by the people who were under the kmcommand of mladic. several thousand bodies have not yet been identified and dna testing is going on. that is something that weighs very heavily on people here. it can drive through other parts of bosnia, especially the serbian part. there are also people who even like mladic. and that's one of the rotational presidents of bosnia which talked about. let's listen in to what he had to say. >> some persons considered him as a hero, as a person, or as a national hero. that man was ready to order killing of thousands of innocent men and boys. and after that, he was -- he wasn't ready to face the justice. he was hiding himself. and he allowed to be arrested in this way. and it is helpful for those who considered him as a hero to understand which kind of man was general mladic. >> reporter: and, of course, zain, one of the things that people keep saying is that internationally they keep hearing the word "closure" when it comes to talking about the case of ratko mladic. and quite frankly, most tell us they have not been able to find closure since he's been arrested because, of course, even if he is put into jail, even if he's put on trial at the hague, many say it won't bring them their families back. i can tell you pretty much every here has suffered under what happened here about 15 years ago, zain. >> cnn's fred plightkin is reporting. he's accused of committing the worst massacre in europe, but will his arrest bring comfort to the thousands of families who suffered? let's bring in a former bosnian negotiator on the peace agreement. thanks for being with us. first of all, how was he able to evade capture for so long? this reflects very badly on the serbian government. >> well, you've had several serbian governments. after the war, milosevic was still in power. clearly he would have been sheltered at that point. i think it's quite clear, on the other hand, that president tadic is not that kind of man, and he he would not have been sheltering him. he is the man who brought him to justice. there's been a lot of collusion. possibly his family, possibly some locals. this is a good demonstration, actually, of the desire, i think, of the serbian government right at the top actually to start writing history. >> you were a major player. you were involved in the peace accords. what were you told about him at the time immediately after his whereabouts? were you ever told the truth? >> no. i mean, clearly, the international community was making inquiries all the time. and as you know, the prosecutor as well as people like myself were constantly making inquiries of the serbian authorities. they professed ignorance. we didn't believe them. and it's pretty clear, i think, that no, they were colluding. i think that era now, i think, is now being brought to a close. with this last very important capture. >> the u.s. and the uk at that time have done more to prevent atrocities like the ones ratko mladic is accused of committing. >> i think we've learned some lessons. i hope we've learned some lessons. the very handling of what's going on in libya is itself an example of a different attitude to people who actually terrorize their own people. you cannot any longer shelter sovereignty as an excuse for behaving in unacceptable ways. >> does serbia deserve to be let into the eu now? >> serbia has made a move which opens a door. there's still a lot to do. this is not yet a perfect society. >> like what? >> they've got quite a lot of technical things they would need to conform to. they need to also be able to demonstrate their systems of justice. they have to render him to the hague. that's important. i have every reason to suppose. it would be very unfortunate that he doesn't get there. let's hope he does. if that happens and they begin to demonstrate that actually this is a country that has the same norms, the same values, that they cooperate with their neighbors, and there are moves going on in that direction, then, you know, the way it does become open, and it's very important for the people of the balkans. they should come into the open union. >> one point to note, too, in his capture is that uk and u.s. intelligence was essential in capturing him, right? >> yeah. yeah. >> and does this bring closure, you think? >> it brings -- it's very hard -- you don't replace people, do you. it doesn't clearly bring closure. it does bring a sense of justice, and i think that's very helpful. and it brings a feeling, actually, is that the world does care about what happened. and that's very important to those who actually suffered. it's an invisible demonstration of the values we're all trying to uphold. so i think it's an important step. and i think that's why everybody is rightly both happy that it's happened but also extremely gratified. >> thank you so much. appreciate it. you're watching "world one" live from london. dozens killed in yemen and the violence there could flare up again as rival factions plan to take to the streets today. and g-8 leaders promise aid for new arab democracies, but what to do about libya?

could there be violence? >> reporter: well, zain, the fear is that there will be violence later in the day. as of now, tens of thousands of supporters of the president on the streets of the capital and tens of thousands of anti-government demonstrators in the capital. there are calls by both groups to have demonstrations. if they mix, there could be clashes and a fear there could be continued clashes between the government forces and the tribesmen that have been fighting. since the overnight hours we've heard of no new clashes. that's led many in yemen to believe there's some sort of mediation process going on, trying to set up a cease-fire. the head of the office is saying that there is a mediation going on, that several influential tribal leaders are trying to implement a cease-fire between both groups. but even though he's saying that, a spokesman for the government is telling us there is no cease-fire being planned. he's saying that the president is accusing the tribe of continuing to attack government targets and government installations. so a very confusing situation, still very chaotic. the mood on the street even though they're relieved that there have been no clashes in the past several hours, they're still very worried. it's still very tense that there could be clashes later in the day. zain? >> mohamed, what does the president want? he's under so much pressure. first he agrees to a possible deal. and then he backs out. then he agrees. then he backs out. then he does that again. can he be trusted? >> reporter: well, zain, by all accounts, diplomats i'm speaking with, government officials in yemen from both the opposition and the ruling party, really people are saying now that he can't be trusted. the gulf cooperation council which was trying to mediate a deal to end the political crisis there, they're very angry with the president now. they think he can't be trusted. the u.s. and the uk putting increased pressure on the president to keep to his commitments, to step down, they're very angry with him because they believe that his intrance jens ai intransigence that will lead to more violence. really not looking good. no one quite understands. he had a deal which he would have been able to get immunity, leave office in a peaceful fashion. he kept saying he was going to and kept reneging on reasons why not to sign this deal. all his supporters seem to be turning against him. he still has some, but more and more, even as his inner circle in yemen are expressing anger, publicly and privately, for not doing the right thing for the country, and they believe that his inaction and the fact that he's been putting up so many impediments to signing this deal when everybody else has signed it that they believe that has really led this country into more chaos right now. zain? >> thanks, mohamed. let's go back to another of our top stories. the u.s. secretary of state and her visit to pakistan, hillary clinton is on a quest to repair relations between the u.s. and pakistan as she arrived in islamabad just a few hours ago with the top u.s. military officer for meetings that have been described as sober in terms of u.s. expectations. our senior u.s. state department producer is traveling with the secretary. elise has just come out of a meeting so we can talk to her now. elise, explain to us what you understand between the public face that we're getting about what's going on and what's happening privately? >> well, zain, we just came out of a press conference with secretary clinton and admiral mike mullen, chairman of the joint chiefs of staff. and actually, it was a conciliatory tone about the u.s. relationship with pakistan, about how critical it is to both the u.s. and pakistani interests and how the u.s. really wants to deepen its cooperation with pakistan. also talking really about the sacrifices that the pakistanis had made in terms of cooperation, the military that they've loved, the civilians that they've loved, really talking in warm terms about moving forward. but behind the scenes, this was a very sobering visit for secretary clinton. these talks were supposed to be very tough in terms of things the u.s. is looking for pakistan to do. relations are at their lowest point because of this raid on osama bin laden's compound. not just because bin laden was hiding in plain sight in the pakistani military, but also because the u.s. went ahead with the raid without talking to the pakistanis about it. so there's a lot of mistrust on both sides. for her part, secretary clinton giving a very tough message in terms of what the u.s. is looking for. action against al qaeda operatives joint operations, going against those factories that produce ieds that are used against u.s. troops in afghanistan and also support for taliban reconciliation with the afghan government. this is seen as key to bringing u.s. troops home, zain. so a lot that the u.s. needs pakistan to do and as tense as the relationship is, both clinton and mullen saying that the relationship is too important to abandon. >> senior u.s. state department producer elise labott traveling with the secretary of state, hillary clinton, in pakistan. thanks, elise. this is "world one" live from london. facebook's billionaire founder admits he's a killer of farm animals, that is. we'll tell you why. and is she lost in translation?
