Libyan rebels have entered Gaddafi's house in Bab al-Aziziya compound, according to rebel sources, dpa reported.
The claim, that the rebels entered the fortified compound through one of its gates, could not be independently verified. Al-Arabiya broadcaster however reported that the rebel flag was seen on top of the house.
There was fierce fighting Tuesday near Libyan leader Moamer Gaddafi's fortified Bab al-Aziziya compound as the battle for Tripoli raged, and broadcaster Al-Arabiya reported that NATO planes had hit the compound with two missiles.
NATO's military spokesman Roland Lavoie refused to confirm rebel-sourced reports that the alliance had bombed the compound overnight, saying, "We do not target individuals and Gaddafi is not a target for NATO."
Explosions were heard earlier Tuesday, and plumes of black smoke were seen rising in parts of Tripoli.
NATO said Tuesday that a "political settlement" was needed to ensure Gaddafi's surrender.
"There is nobody who could predict exactly when exactly the Gaddafi forces will finally drop their weapons. They will do so only when there will be a political settlement to the conflict," NATO's Lavoie said.
