People cover their noses from the smell of burnt bodies in a warehouse on August 27, 2011 in Tripoli, Libya. Up to 150 people were found dead, 53 bodies were burnt in a warehouse in the last few days. The victims are believed to be Libyan civilians arrested by pro-Gaddafi loyalists for interrogation. As the Libyan rebel forces were advancing, the pro-Gaddafi forces acted to cover up the bodies of the people they were interrogating, they threw in grenades and then had subsequently set fire to tyres inside of the warehouse to cover up the bodies, locals said. Heavy fighting continues in the Libyan capital between Gaddafi's forces and the surging rebel presence. (Photo by Daniel Berehulak/Getty Images)

Burnt bodies are seen in a warehouse at the site of a massacre, on August 28, 2011 in Tripoli, Libya. Up to 145 people were detained in a warehouse which was then set on fire to on the 23rd of August, locals said. The people, Libyan civilians, were arrested by pro-Gaddafi loyalists for interrogation, some of them months ago. As the Libyan rebel forces were advancing the pro-Gaddafi forces started to shoot the detainees and continued to throw grenades into the warehouse, in order to cover up the interrogations. 35 people escaped as the guards were reloading their weapons, according to a survivor, Abed Rizaq Ghazim Senussi from the city of Grames, he being one of them.
