INDIA, March 21 -- A United Nations appeals court on Wednesday increased the 40-year sentence initially imposed on Radovan Karadzic, former leader of the Republika Srpksa region of Bosnia and head of the Bosnian-Serb Army, to life imprisonment.

In 2016, the International Criminal Tribunal for the Former Yugoslavia (ICTY), found the 1990s wartime leader guilty of genocide and war crimes, including the planning of the notorious 1995 Srebrenica massacre, during which some 8,000 Bosnian Serbs were murdered. The aftermath was described at the time as resembling "scenes from Hell" by a Tribunal judge. Karadzicwas also found responsible for the three-year long siege of Sarajevo, which led to the deaths of an estimated 10,000 civilians.
