COLOMBO: Workers have discovered a possible mass grave with 49 human skulls during two weeks of excavations on a construction site in central Sri Lanka.
Police spokesman Prishantha Jayakody said Friday the skulls plus other bones were found during excavation work for an extension on a hospital in Matale town.
Jayakody said other details about the bones and the burial site were immediately not known.
But the People s Liberation Front, a Marxist group that carried out two armed insurrection since 1971, called for an investigation to see if the site is a mass grave where its members were buried after being killed by government soldiers.
The group s clashes with government troops left heavy casualties on both sides.
