Bosnian Serb general Zdravko Tolimir, who was serving a life sentence for genocide, has died in detention at the UN International Criminal Tribunal for former Yugoslavia (ICTY), Belgrade authorities said Tuesday.
The head of Serbia's body in charge of cooperation with ICTY, Rasim Ljajic, confirmed the news of Tolimir's death, but gave no other details, state broadcaster RTS reported.
ICTY was unable to immediately confirm the report.
A high-ranking commander of the Bosnian Serb army intelligence service, Tolimir, 67, was found guilty of six counts of war crimes, including genocide, in December 2012 and sentenced to spend the rest of his life in prison.
During the siege of Srebrenica, a town that was a Muslim enclave in Serb territory during the 1992-95 Bosnian war, Tolimir reported directly to the Serb military commander Ratko Mladic, who is presently on a genocide trial at the ICTY.
In the 2012 sentencing, the court made a "conservative estimate" that the Bosnian Serb military killed "at least 4,917" Muslims in Srebrenica after they rolled into the enclave in July 1995.
Generally, the number of victims, mostly able-bodied men, is estimated at between 7,000 and 8,000. The Serbs expelled women, children and the elderly.
