Tripoli , Libya ( CNN ) -- Fugitive Libyan leader Moammar Gadhafi 's compound was strewn with shell casings and litter two days after its capture by rebel forces , while the bodies of a dozen bound men lay in a nearby intersection . The sprawling complex was littered with spent anti-aircraft shells , with rebel fighters picking through the detritus of the life Gadhafi 's supporters left behind when they fled . An armored BMW sedan sat abandoned in a garage near the `` House of Resistance , '' the bombed-out building that Gadhafi left unrepaired as a monument to a 1986 U.S. airstrike that killed one of his daughters . Several NATO airstrikes and the onslaught that led to the fall of the Bab al-Aziziya compound on Tuesday inflicted more damage on the site , the symbolic heart of Gadhafi 's nearly 42-year rule . But during a visit by CNN to part of the compound on Thursday , there was no sign of the network of tunnels and bunkers long believed to have been built beneath Gadhafi 's headquarters . Nor was there any sign of Gadhafi or his sons , the subjects of an intense manhunt since their regime crumbled . The streets outside Bab al-Aziziya are awash in guns and rumors , including one that saw rebel fighters surround a nearby apartment complex Thursday on a tip that Gadhafi was inside . He was not found . The National Transitional Council , the rebel leadership , says it is determined to flush him out with minimal civilian losses . `` We do n't want to spill a lot of blood , you know , because they are our brothers , '' one rebel fighter said . At a nearby intersection , a dozen bodies lay in the sun , some of them with their hands bound . Rebel fighters say the men were executed by Gadhafi 's retreating forces . But the bodies appear to be those of black Africans , who made up a large portion of the pro-Gadhafi forces , raising questions about whether the men may have been executed by the rebels . To the south of the compound , which is located near Tripoli 's Mediterranean shore , fighting between rebel fighters and Gadhafi loyalists persisted . Snipers and mortar shells continued to inflict casualties on hundreds of civilians , said Kirstie Campbell , a worker for the International Medical Corps in Tripoli . `` I 've worked in war zones for 10 years , but this is pretty bad , '' she said . CNN 's Dan Rivers and Thomas Evans contributed to this report .
