"Bab al-Azizya was nothing but a heap of rubble after it had been the target of 64 Nato missiles and we withdrew from it with regard to tactical reasons, " he said in a speech carried by the website of the television station headed by his son Seif al-Islam.
The speech also quoted through the pro-Gaddafi Al-Oruba channel came after rebel fighters stormed the sprawling compound but found no trace of him or some of his family.
It gave no indication of where he had gone.
Simultaneously Gaddafi spokesman Mussa Ibrahim told the Syrian-based Arrai channel that more compared to 6, 500 "volunteers" had arrived in Tripoli to fight for the regime and required more.
"The volunteers can come to Libya and we will give all of them weapons, ammunition and training, " he said.
Ibrahim said Gaddafi's forces had captured several rebel leaders and warned when Nato raids continued "we will turn Libya into a brazier and we are able to protect civilians from the crusader gangs and alliances. ".
