Tripoli. Salahuddin District. 27th August 2011.\nOne of the worst single atrocities documented so far during Libya's revolution may include as many as 140 victims, carried out by militiamen loyal to Colonel Gadaffi. It occured in a yard used to store farm machinery in the Salahuddin district of Tripoli, adjacent to the capitals largest military base. The prisoners-suspected of suporting the rebels- were herded into a barn adjacent to Tripoli's largest military headquarters, where they were machine gunned. Hand grenades were thrown at survivors before the bodies were set alight. This is one of the worst single atrocities documented so far during Libya's revolution and survivors place Col. Gadaffi's son Khamis at the scene giving orders shortly before the exections began. At least 7 men escaped the killings, but the bodies of up to 90 others, also believed to have been killed there, are still missing. Mounds of bulldozed earth in the yard suggest the presence of a mass grave.
