to an end. libyan rebels made fast and furious advances over the weekend. they claim they now control a great majority of tripoli. it could be a mortal blow to leader moammar gadhafi's 42-year rule. some of his forces are still putting up a fight. there have been reports of tank fire near gadhafi's home. there was no sign of gadhafi yet himself. the rebels are saying they've got three of their sons and opposition leaders already are making plan to govern. [ crowd noise ] >> as you might expect, there are celebrations around the world. libyans living in manchester, england, took to the streets to celebrate the leader's push into tripoli. >> we've been suppressed for 42 years. now we're testing the freedom, the freedom of speech, the freedom of movement, the freedom of everything that mean libyan people are free, no longer suppressed, and gadhafi, the dictator, is out, his sons are being captured, and we are -- we can't describe the joy we're feeling right now. [ crowd noise ] and libyan natives went to the libyan consulate in alexandria in egypt to celebrate the news. egypt helped inspire the revolution in libya back in february, three days after the fall of the egyptian president, hosni mubarak, calls went out on facebook for peaceful protests against moammar gadhafi. cnn's sara seidner was with the rebels as they arrived at the heart of their grand prize, green square in tripoli. it was clear that the rebels' victory wasn't complete. here's sara's report. >> reporter: right now what's happening is everyone's -- [ gunfire]] >> we're in the middle of tripoli. there are rebels all over the square. there are really no civilians, mostly men with guns in the square. we're also seeing people running. there's a lot of gunfire. they say there are snipers. we had to pull back. the situation very tense here. but there is a lot of celebrating going on. some of this is just gunfire in the air. but people are very concerned because they say there were sniper posted at the top of some buildings. they're not sure exactly where some of the gunfire is coming from. every now and then you see people running to get out of the way. the rebels have green square, and it is a historic moment here in tripoli, in the capital. the real stronghold of moammar gadhafi has been taken over by the rebels. >> cnn's sara sidner joins us now. describe what's happening around you. >> reporter: i can barely hear you. i can tell you what's going on. in this area -- we are on the main drag that leads into green square, and we can hear lots of celebrating -- we can hear basically people shooting in the air a little bit. mostly what you're see regular just trucks full of men, armed men with rebel flags flying. they are -- [ inaudible ] moving into green square, yelling "god is great." this is a victory. everyone's saying you're seeing history, moammar gadhafi is gone. no more moammar gadhafi. but nobody has actually seen him. there are still some gadhafi troops in this city, the rebels are saying they have not been able to clear the city, but they say they have control of most of it. and they are very, very excited today. they believe that this is their final, final push to getting gadhafi forces completely out of the city. we do know they have engaged -- we see some people running around buildings and at the gas station where we're standing now. it's still tense but mostly the mood is one of relief. there's -- the strange sense here because we're seeing finally a few, just a few residents who are sticking their heads out windows, putting the victory sign out. obviously some of this city certainly did support the gadhafi regime. so unlike other cities where we've been like misrata and benghazi where there were more and more people who felt comfortable coming out against the regime, here you have a little bit different situation. we are seeing a few residents out and about and cheering the rebels on. >> sara, do the rebels you're with believe that they may still have to engage loyalist gadhafi forces even now? >> reporter: we came into the city -- and this is significant -- without any escort. we came into the city, we had hardly any trouble getting in. there were no checkpoint up until we got relatively close to the city square. yes, there is a certain amount of caution. we are being told that there are snipers in some areas still. we're going told that they have not been able to completely clear out certain sections of the city. this is, you know -- this is tripoli, the capital. there are a lot of buildings here, there's a lot of space. but mostly in the street, all we're seeing are rebel cars filled with men holding guns, celebrating, waving the flag, and a few resident around watching them as they go about trying to go street by street looking to try and push out or find any of gadhafi's remaining support and remaining troops. >> sara, this is carol. i was just wondering -- everybody's wondering where moammar gadhafi is. is it possible that he could slip out of tripoli? >> reporter: anything's possible. but, you know, the problem here is that the speculation goes wildly one way and then another. for a long time there were rumors that he had left, then there were rumors that he was holed up in his compound, under his compound. the rumors are really rampant, and i think nobody really knows except for his inner circle exactly what is going on with him, where he is, what he's doing, what state he's in, what state his family is in. again, after hearing of the arrest of his sons, this place just went absolutely wild overnight. but nobody yet has any solid information as to exactly where moammar gadhafi is. >> and just in looking forward, say tripoli is completely taken by these rebels, what happens then? who's in control? >> reporter: well, that's a great question. what we're seeing is something very interesting because we thought that they would be really wildly celebrating and shooting as they have been in every single city and doing doughnuts in the street and just being a bit wild. and that's not what's happening here. it's almost a sense, these rebels did not expect it to come so soon. they're looking around and trying to assess. i think they're as surprised as anyone that they made it to the city so quickly. as for going forward, what political mechanism will be put in place? the national political council that was being put together in benghazi with people from different tribal councils trying to make up the group, they have had issue, they had to get rid of their executive committee because of the killing of one of the commanders of the rebel forces. but what we're seeing is a slow process of trying to figure out who is going to lead. the council has said what they will do is try to facilitate. they will be an interim government, but those who are members of that council will not try and run for office. they want to have a free and fair election with a solid constitutional that allows freedom for their people. so this is going to be quite a process, but it's a good question as to who will lead this country if indeed moammar gadhafi is captured, caught, or leaves the area. >> carol, we're just receiving new information right now. according to one rebel spokesman, moammar gadhafi's forces in one tripoli neighborhood are negotiating their surrender. the name of the neighborhood negotiations are said to be occurring is the tajura neighborhood, one of three areas in the libyan capital where gadhafi's forces are still believed to be in control. it's also the neighborhood that's home to a hospital, and gadhafi forces are asking to surrender according to the rebel spokesperson right now. carol? >> things still very fluid. thank you. the rebels say they have detained three of gadhafi's son, we've been telling but. that one could end up in the netherlands. today the international criminal court is working to bring saifal islam to the hague. muhammad has been restricted at his home. one offal jazeera's -- one of al jazeera's reporter gave a statement -- >> translator: there's gunfire outside my house. they're outside my house. good-bye, good-bye, good-bye. >> al jazeera reported that they were not harmed but movements were under the control of rebel forces. the european union is urging gadhafi to step down without delay, and nato says the sooner gadhafi realizes he can't win the better it will be for the people. the alliance has conducted about 7,500 strikes on libya since the end of march to protect civilians from gadhafi. here's what a nato spokeswoman said. >> those responsible for starting the bloodshed in libya are the gadhafi regime. as the united nations security council resolution made clear, the mandate of nato is to continue protecting civilians and civilian-populated areas against the threat of attacks, and what we've seen consistently, systematically and brutally are attacks by the gadhafi regime, ever since february. and nato has consistently implemented that mandate, and we have saved countless lives since we started this mission. >> nato, as you know, has been enforcing a no-fly zones and an arms embargo as part of its libya mission. >> could the end be near in the case against against dominique strauss-kahn?

[ gunfire ] [ cheering ] celebrations on the streets of benghazi, libya. moammar gadhafi may be gone, may be running. i'm carol costello live in new york. >> nobody knows where exactly he is. that is the big question right now. i'm zain verjee. there are celebrations erupting across libya as rebels capture tripoli. earlier there was a young resident in tripoli. we talked to our reporter about what she was hearing in the city. let's just listen. >> reporter: all the men of our area downtown went out for the first time in 42 years. finally they feel like they're free. they have some freedom of speech. right now we hear gunshots, not sure where they're coming from. everyone went out, all of the men were outside on the streets, the women were outside on the balconies screaming, chanting anti-gadhafi slogans, and we feel like it's so close, we're winning, it's the end. >> it's so close. so let's switch gears just a tad. how are the world markets reacting to the fall of trichly, and what -- tripoli, and what does this mean to oil prices? so how what's happening in libya affecting the world markets? >> well, oil producers are trading higher. in fact, in europe we're seeing gains from companies like bp, petrofac, and total after rebel forces entered the libyan capital and seized much of tripoli. the thinking is that the possible end of the government would allow companies to access oil fields that have been closed by the ongoing civil war. overall, the markets in europe with the exception of the dax appear to be on the rise. but it's a different story in asia. the nikkei closed down 1%. the seoul kospi closed down 2%. asia remains focused on the risks of growth in the global market turmoil. >> i know the united states doesn't directly get oil from libya, but how might what's happening in libya affect oil prices? >> well, right now oil prices are falling. and analysts expect prices to fall even further as the civil war looks to be coming to an end. libya's economy is heavily dependent on oil. it's a key revenue stream that's been cut off during this months' long conflict. libya was producing more than 1.5 million barrels per day. that means it supplied 2% of the energy the world consumed on a daily base i. libya clearly has -- basis. libya clearly has an impact on the global oil supply. you can expect the price to fall as the supply increases. carol, back to you in new york. >> reporting live from hong kong, many thanks. president obama watching developments in libya closely. ahead, his strongly worded statement about moammar gadhafi as the dictator's 42-year rule crumbles around him. puppy food brand? ca's numbere with dha and essential nutrients also found in mother's milk. purina puppy chow. announcer: when life's this hard, it's no wonder 7,000 students drop out every school day. visit boostup.org and help kids in your community stay in school. good morning to you. i'm carol costello in new york. >> and i'm zain verjee in london. carol, today could be going down in history as the day a dictator's long, tight grip came to an end. the speed that it's happening at is so astonishing. moammar gadhafi has controlled libya for 42 years. and it appears to be on the brink of collapse. right now at this moment, everyone asking where is he, is he even in tripoli? his compound has been surrounded. there's a lot of fighting around it. we don't even know if he is in the city. there have been mass defections, three of his son have been captured by rebels, they're in custody. the rebels have marcheded on tripoli, carol. >> yeah. we also have word that moammar gadhafi's forces in one tripoli neighborhood are actually negotiating their surrender with rebels, certainly a good sign. as you said, three of gadhafi's sons in custody. but the mystery today, as you said, where is moammar gadhafi? some people believe he escaped the country or maybe he could be hiding inside of tripoli. anything is possible at this point. >> it really is. we're going to keep a close eye on it. we're also taking a look at some of the great video and sound coming in from libya and around the world of so many people celebrating as rebels appear to be on the brink of toppling gadhafi's regime. a few minutes ago we talked to cnn's sara sidner who says rebels may be celebrating in green square now but they've not cleared tripoli yet. watch this. after 42 years it seems that gadhafi might, might just go where he belongs. to hell. >> this is video from the eastern part of the country in benghazi, a rebel stronghold. ireporters sent in video. thousands gathering, as you see, to show support for the rebel advance on the capital tripoli. they were amazed, carol, moments ago, sara sidner reporting that they murderly met any resistance -- hardly met any resistance as they came into zawiya and tripoli. [ crowd noise ] >> that question remains up in the air h. is video of -- air. this is video of libyans that gathered outside the consulate in egypt. one man climbed to the top of the consulate and replaced the libyan flag with the independence flag. egyptians are no stranger to revolution having recently toppled its crushing rule of w hosni mubarak. >> men, women, and children waving libyan flags and holding signs, carol, that read "finally." there were chants of "usa, usa," "soifd -- "gadhafi is gone today, libya free." >> we'll check with sara sidner in triply after the break, in the thick of things. discover aveeno positively radiant tinted moisturizers with scientifically proven soy complex and natural minerals. give you sheer coverage instantly, then go on to even skin tone in four weeks. aveeno tinted moisturizers. ♪ for a snack like you ♪ to come into my life [ female announcer ] lean cuisine has snacks! like creamy cheesy spinach artichoke dip with warm pita. new from lean cuisine®. good morning to you, it's monday, august 22, this is your "a.m. wake-up call," i'm carol costello live in new york. it's 29 minutes past the hour. i'm zain verjee live in london. friday we hardly mentioned libya. now we're talking about the end of a 42-year regime. so how did things seem to turn so quickly in the rebels' favor? >> it did go along at lightning speed. first of all, the rebels, they captured the city of zawiya, about 30 miles from the capital. one it went down, tripoli could not be far behind. sara sidner rode with the rebels as they approached their biggest prize. gadhafi finished, finished. gadhafi finished, very, very happy. >> reporter: what you're seeing behind me are a few people saying there's going to be a massive battle here. they do not have full control of the city. >> at the moment, we are not fully control of tripoli because you can see that. >> reporter: what does this make -- how do you feel about this day? are you from tripoli? >> yeah. >> reporter: why is this day important? >> it's historic day because we had to leave from here -- now we had to fight. i'm not a fighter. it at my first time. -- it's my first time. >> reporter: the civilians are leaving, and now we also have to leave. [ gunfire ] >> reporter: what's happening is everyone is running. [ inaudible ] >> we're in the middle of tripoli. we're seeing rebels all over the squa
