Gaddafi's control continued to weaken a week after rebels stormed Tripoli and bombarded his compound on Aug. 22.

"The dramatic scenes we are witnessing in Tripoli, Libya, are a testament to the courage and determination of the Libyan people to seek a free and democratic future," Secretary Ban said on Aug. 22.

"Although it's clear that Gaddafi's rule is over, he still has the opportunity to reduce further bloodshed by explicitly relinquishing power to the people of Libya and calling for those forces that continue to fight to lay down their arms for the sake of Libya," President Barack Obama said on Aug. 22.

Gaddafi remained hidden from rebels and NATO forces on Monday and the leader

had not re-emerged since Wednesday when a Libyan television channel broadcast his comments that pro-government forces would not surrender until they achieved victory or were killed.
