Libyan citizens took over Tripoli's main square on Sunday night, as rebel forces claimed to have taken control of much of the capital, and captured two of Muammar Qaddafi's sons. Rebel gains in the past several days brought them to the outskirts of Tripoli, and they practically sped into neighborhoods of the city on Sunday, facing minimal resistance. Qaddafi remains defiant, if unseen, issuing radio statements urging residents of Tripoli to rise up against the rebels. Even as celebrations took place in Benghazi and parts of Tripoli, fighting continues, and Muammar Qaddafi remains nominally in power, even though he appears to have effectively lost much of his control.
