Argentine judicial officials say anthropologists have discovered a common grave with the remains of at least 15 people apparently slain by a military dictatorship.
The Argentine judicial system reported in a news release that forensic anthropologists found the remains at what was a major clandestine detention center holding suspected dissidents during the 1976-1983 dictatorship.
Some of the victims had their hands tied and they appeared to have been shot.
The investigators are helping a judge probe activities at a military arsenal in the northern state of Tucuman during an army crackdown on leftist guerrillas.
Human rights groups say about 30,000 people were killed under the military regime.
