Rebel forces have overrun Colonel Gaddafi's Bab al-Aziziya compound in central Tripoli. The heavily fortified complex has already been damaged in Nato airstrikes since April.
Comparisons with satellite imagery from 2010 show how a Libyan government planning and communications centre has been extensively damaged in airstrikes.
Col Gaddafi's personal library and office buildings have sustained considerable damage from Nato bombing.
Other buildings on the compound have been reduced to rubble by the air strikes.
Images from June 2011 showed a possible camp for supporters of Colonel Gaddafi inside the compound near his main residence.
Nato jets, including RAF ground attack aircraft, have carried out precision strikes against the military vehicle and equipment next to the compound.
The images were taken on 18 June by DigitalGlobe, with analysis based on Unosat and DigitalGlobe FirstWatch Analysis.
Two days earlier, the compound was attacked by Nato aircraft as part of their operation to weaken Gaddafi's military.
Nato later confirmed that "an intensification of air strikes has resulted in the destruction of crucial command-and-control nodes, military equipment and ammunition storage facilities, particularly within the vast Bab al-Aziziya presidential compound".
