The corpses of 25 people wrapped in plastic sheets were found on Wednesday in the city of Sirte by government forces, who accused militias fighting for deposed leader Muammar Gaddafi of execution-style killings.
A Reuters team counted 25 corpses in plastic bags in a southern area of Sirte called "Neighbourhood 2". Five corpses shown to the team had their hands tied behind their backs and gunshot wounds to the head. They wore civilian clothes.
A commander with the National Transitional Council (NTC) said the corpses had been there for at least five days.
