Meanwhile, in Libya, more than 50 bodies have been found at a warehouse in Tripoli, behind the headquarters of a feared army unit, the Khamis Brigade, led by one of Colonel Gaddafi's sons.

Survivors say they were civilians, massacred by Gaddafi's forces earlier this week. It is the smell that forewarns you of the horrors to come. The nauseating stench of death reached out from the warehouse, curling around us, like a physical presence. Read the report in the BBC.
