Ratko Mladic, the former Bosnian Serb military commander convicted of war crimes and genocide during the 1990s conflict, died on Saturday at the age of 84. Mladic had been serving a life sentence at a prison in The Hague after the International Criminal Tribunal for the former Yugoslavia found him guilty of overseeing the siege of Sarajevo and the Srebrenica massacre. His death was attributed to natural causes, according to a statement from the International Residual Mechanism for Criminal Tribunals. Human rights groups noted that his passing closes a grim chapter in the region’s history, while victims’ families expressed mixed feelings of relief and lingering grief.
