Libya: Inside Gaddafi's underground fortress

25 August 2011 Last updated at 19:09 BST

The BBC has gained access to the network of tunnels used by Col Gaddafi inside his compound.

Describing them as an "underground fortress", the team found abandoned supplies and a motorised cart that could have been used to transport Col Gaddafi through the tunnels.

In the compound above ground, dead bodies lay where they fell, as Orla Guerin reports.
