couple uncoupled. we look behind the breakup of maria shriver and arnold schwarzenegger. the road to nowhere. the mississippi's rising water levels turned river side communities into ghost towns as thousands are forced to get out. and meet a real hamburger fan with an appetite for big macs that is undiminished after 39 years. to heal the past, queen elizabeth's visit to ireland moves into what could be the most significant day with a visit to the site of a british massacre. hours from now all of ireland will be watching as the queen visits a stadium where in 1920 british troops opened fire on a crowd watching a football match. 14 people were killed. it was a key moment for the irish independence struggle and came to be known as bloody sunday. for many, the sight of a british monarch walking on to the pitch will be a deeply symbolic moment. mr. cameron is due to talk business and politics with irish prime minister. on such a big day, the queen might light some dutch courage. in about a half hour she has a chance to sample a pint of stout at the guinness brewery, one of ireland's top tourist destinations. let's go to cnn's nula sweeney. >> reporter: the queen is due today in her engagements to go to the guinness factory. one of ireland's most famous exports. the guinness family is an old anglo irish family. and the fact i have one of the legacies here at sir james' gate in dublin. heads of state don't apologize for past doings or wrongdoings. and so no apologies expected here. that's left up to prime ministers and heads of government. but essentially people will be watching to hear what the queen has to say. today, as you pointed out, one of the most significant moments of this visit. you pointed out that 14 spectators at the football game were killed by british force onz that day, bloody sunday, during the height of the civil war. it was in retaliation of the killings of 14 british int intelligence officers earlier in the day. but the authorities on both sides of the irish seat are happy with how the visit has gone so far. of course, dublin still in a state of lockdown really. security is parra mouir paramou visit. they're talking about how this is not so much the ending of a chapter but the opening of a new one. >> so we had seen in the last day that there had been small dman stra demonstrations. on the other side of that, have we seen large crowds of supporters? >> large crowds of supporters are not encouraged on to the streets here because of the paramount emphasis on security. there were small pockets of demonstrations yesterday, 50 to 100 people demonstrating against the visit. 20 arrests were made. but essentially because of the security situation, this queen is traveling down roads but not really meeting anybody on those routes. the main roads she's travel ago long are blocked off. the adjacent roads are also sealed off. >> all right. thank you for that. of course, we'll check in with you later on. the queen's first ever visit to ireland is a popular online topic in europe. let's see what some people are saying on twitter. let's start here in ireland and adrian says "i genuinely hope the queen of england has a pleasant stay in ireland and there is no drama. we have come a long way." also going on here in ireland. "kind of scared to be living in ireland this week because the queen is visiting and loads of irish people don't seem to like that." we saw that video there. some small pockets of demonstrators. and in britain, "the irish in me is smiling. the english in me is cheering. about time the queen gets to ireland. we all know she'll love it." and then on the continent, let's go to germany. "the queen is as welcomed as foreign investment and tourist revenue. hope ireland does well." questions are being raised over the whereabouts of libya's oil minister amid reports he may have quit gadhafi's government. a north african news agency says that he crossed into tune eeisi after the week end. he checked into a hotel on an island off tunisia. if he has left his job, it puts further pressure on colonel gadhafi who already had one top minister defect and just this week a chief prosecutor at the international criminal court said he is seeking an arrest warrant for the libyan leader on suspicion of committing more crimes. on the other side of the world, canadian authorities in ottawa expelled five libyan diplomats saying behavior was inappropriate. the five men were all working at the libyan embassy. they and their families have been told to leave within days. the canadian government hasn't given any further details. but recent media reports suggest some libyan nationals in canada who were speaking out against the gadhafi regime had been threatened and intimidated. back in libya, there's been more fighting between rebels and forces loyal to colonel gadhafi in the west. opposition fighters are calling for help after coming under heahe heavy bombardment. let's bring in our reporter who is in the capital, tripoli, with more on that. tell us a little bit about the latest that is taking place right now. of course, let's begin with the diplomats that have been expelled. >> reporter: there is definitely a sense here that the libyan government is feeling that pressure. there's a lot of pressure being placed internationally on them and that that pressure is definitely starting to yield a few results here on the ground. overed weekend we saw the u.n. envoy here in tripoli to discuss a u.n. brokered cease-fire. now there's a lot of distance between what the rebels want in terms of negotiation and what the government wants in terms of negotiations for that cease-fire. but what the u.n. had said when we were arriving here in tripoli is that what we want to do is they put out a buffer zone which at the moment is being discussed as a cease-fire and then sort out the difference. and the fact that the libyan government played host to the envoy even though his position very different from theirs i think is very telling. and the fact that libyans were telling us that they were the ones who invited that envoy. and i think perhaps gives people a little bit of hope that we are moving towards a place in spite of the hostilities on going in the east whether the libyan government is seeking to try to find a political way through this. >> are we seeing, i guess, a different phase now of this offensive taking place now? on the one hand we spoke there of the oil minister reportedly defecting, although, we don't know where he is. and now there are reports that gadhafi is using another type of mortar. is there a sense he is upping the ante now? >> there is definitely a sense that he's trying while there is had pursuit of the political route through that he's definitely trying to break the impasse perhaps to insure that the position of the libyan government when they sit down and negotiate say it is a strong one. there is a little bit of a stalemate on both sides. the territory has been taken is very much the territory as it stands now and as it stood for quite a while now. so we've had these conflicting reports over who has power over the court, the airport and just the territory that the area around the capital. they're trying to breakthrough that and negotiate. >> all right. thank you for that. now it may come as no surprise that the al qaeda terror group is moving on. it's been more than two weeks since osama bin laden's killed by u.s. forces inside pakistan. and now a source with detailed knowledge of al qaeda says the group has a new interim leader, egyptian former special forces saif-al-adel, one of the fbi's most wanted terrorists. according to reformed ex-militants, the interim appointment may be a way to measure reaction to a leader from beyond the arabian peninsula, a region holy to all muslims. you're watching "world one" live from london. surging south. we're tracking the wall of water sweeping through communities in the mississippi valley. and what pushes the rich and powerful to cheat on their partners? the high profile husbands who stray. hey, i'm troy polamalu, and i owe my great hair to head & shoulders. it gives me a healthy scalp and great looking hair. you making fun of me? no. you making fun of me? yes.
