Qaddafi, his family, and his closest advisers barricaded themselves inside the well-protected Bab al-Aziziya compound, a group of military barracks that has become the regime’s home base for much of the uprising.
Located on the city’s outskirts, the compound seems to be one of the few places in Tripoli still under Libyan government control. On Monday, rebel forces attempting to infiltrate the compound were turned back by tanks and heavy fire.
NATO has bombed the compound, a part of which remains in ruins from a 1986 US bombing, several times since it began operations in Libya this spring.
