A Bosnian Serb general, described as commander Ratko Mladic’s right-hand man during the Bosnia war, has died in custody in The Hague.
Serbian officials said he had died on Monday night at the war crimes tribunal’s detention facility.
Gen Zdravko Tolimir, 67, was given a life term in jail for genocide by UN judges in 2012.
The tribunal rejected an appeal last year, citing his role in the 1995 Srebrenica massacre.
About 8,000 Bosniak men and boys were murdered at Srebrenica in the worst massacre of civilians on European soil since World War Two.
Gen Mladic is also on trial at The Hague, accused of genocide, war crimes and crimes against humanity.
