In the dimly lit tunnels, the scouts rummaged through a bedroom and came across bank of black phones, which could have once connected Qaddafi to the world above ground or to other parts of the tunnel network. Former Libyan officials have reportedly said the tunnels connected the Tripoli compound to the outer reaches of the capital city.

A shot of a massive hole exposing the tunnels to the outside might have been the result of a NATO airstrike during the alliance's bombing campaign that aided the rebels.
