National Transitional Council authorities discovered the remains of over 1270 Libyans killed by the Gaddafi regime more than fifteen years ago.
The victims were all prisoners at the Abu Salim prison, massacred during a protest against conditions on 26th June 1996.
It is understood that international assistance will be sought to identify the remains.
The overthrow of Gaddafi's regime has led to numerous unsettling discoveries, including a stockpile of mustard gas in the Southern desert.
