AMANPOUR: With no money, no airline tickets, and little hope of making it on to a flight, these people have no idea how much longer they'll have to camp outside, as mounds of garbage pile up beside them.
We've left that sea of humanity behind at the airport. There were some soldiers guarding the entrance of the airport, but now we're driving into Tripoli itself. And so far, there is no sign of any violence or any conflict on this road.
After the eerie calm of the streets, a colorful neon welcome at the designated journalists hotel, a surreal scene since we've been told the city was now ringed with tans and pro-Gadhafi forces.
Earlier Saturday, reports that 500 miles to the east, cities along the Mediterranean coast had largely fallen. Tens of thousands of anti-government demonstrators celebrated there in Libya's second largest city Benghazi.
UNIDENTIFIED MALE: I have never been as happy as today in my whole life.
AMANPOUR: And they were not alone. All along the coast, they were firing guns into the air, taking control of radio station, even mocking and impersonating their leader of more than four decades. All this, as after a week of protests and violent reprisals, President Obama issued a statement and said that Gadhafi needs to do what is right for his country by leaving now.
I sat down for exclusive interviews with Gadhafi's sons. First, I spoke to Saif al Islam who is also one of his chief advisers.
Thank you for joining us.
The president of the United States, President Obama, has called on your father to step down. What do you think of that?
SAIF GADHAFI, MOAMMAR GADHAFI'S SON: First of all, it's not an American business. That's number one. Second, do you think this is a solution? Of course not.
AMANPOUR: Says if a person can only keep control by using force, then legitimacy is gone.
SAIF GADHAFI: Right. But what happened? We didn't use force. Second, we still have people around us. So we are in Tripoli. In Tripoli, we have here half of the population of Libya -- half. That's more than 2 million, 2.5 million people living in the city. Do you think because of 10,000 or 5,000 people, even if you have the demands against my father or whatever, it means that the whole Libyan population is against Mr. Gadhafi?
AMANPOUR: You said you're not using violence. But there are many reports of helicopter gunships, of people being killed, and also air force pilots defecting, jettisoning their planes rather than carry out ordered to bomb citizens?
SAIF GADHAFI: Show me a single attack. Show me a single bomb. Show me a single casualties. The Libyan air force destroyed just the ammunition sites.
AMANPOUR: What do you make of your diplomats in New York, for instance, in Washington who are resigning because they say they can't abide this policy?
SAIF GADHAFI: I talk to them.
AMANPOUR: Why do you think people are deserting your father?
SAIF GADHAFI: Many of them -- they think the system will collapse. So the best thing is to jump from the ship. The ship is sinking, they think, so it's better to jump.
AMANPOUR: Will there be a new regime?
SAIF GADHAFI: If you are strong, they love you. If not, they say good-bye. That is good. We get rid of them. Hypocrites.
AMANPOUR: Do you think they'll get rid of you?
SAIF GADHAFI: No. They are the leaders. They have no future. They want to join the youth revolution.
