"We can say with certainty that those are victims killed in the area of Prijedor, local villages and the Omarska and Keraterm concentration camps," the spokeswoman for the Bosnian Missing Persons Institute (INO), Lejla Cengic, was quoted as saying, adding that the identification documents found with the remains facilitated the investigation.
Exhumations at the mass grave near the Tomasica mine began on September 3 and the remains of 390 people have been found so far, including 233 full skeletons.
Forensic experts have confirmed that Tomasica was a primary mass grave from which some bodies were transferred to the Jakarine Kose area, where the remains of 373 people were found in 2001.
According to estimates, at least 800 people were buried at Tomasica, making it one of the biggest mass graves in the country.
It is also estimated that Bosnian Serb paramilitaries killed more than 3,000 Croats and Bosniaks in the Prijedor area in 1992.
Bosnia is still looking for the bodies of about 1,200 victims, including 70 children, according to INO data.
