TRIPOLI, Libya —
Government spokesman Moussa Ibrahim also claimed the regime has "thousands and thousands of fighters" and vowed: "We will fight. We have whole cities on our sides. They are coming en masse to protect Tripoli to join the fight."
Gadhafi's former right-hand man, who defected last week to Italy, said the longtime leader would not go easily.
"I think it's impossible that he'll surrender," Abdel-Salam Jalloud said in an interview broadcast on Italian RAI state radio, adding that "He doesn't have the courage, like Hitler, to kill himself."
Jalloud, who was Gadhafi's closest aide for decades before falling out with the leader in the 1990s, fled Tripoli on Friday, according to rebels.
The startling rebel breakthrough, after a long deadlock in Libya's 6-month-old civil war, was the culmination of a closely coordinated plan by rebels, NATO and anti-Gadhafi residents inside Tripoli, rebel leaders said. Rebel fighters from the west swept over 20 miles (30 kilometers) in a matter of hours Sunday, taking town after town and overwhelming a major military base as residents poured out to cheer them. At the same time, Tripoli residents secretly armed by rebels rose up.
When rebels reached the gates of Tripoli, the special battalion entrusted by Gadhafi with guarding the capital promptly surrendered. The reason: Its commander, whose brother had been executed by Gadhafi years ago, was secretly loyal to the rebellion, a senior rebel official, Fathi al-Baja, told The Associated Press.
On Monday, rebels erected checkpoints on the western approaches to the city, handing out candy to passengers and inquiring about their destination. Cars leaving the city were subjected to more rigorous checks.
