THE HAGUE, Netherlands (AP) — A U.N. war crimes court convicted a former senior Bosnian Serb army commander Wednesday of genocide for playing a key role in Europe’s worst massacre since World War II and sentenced him to life imprisonment, delivering another measure of justice to survivors still hunting for the remains of their husbands and sons.

In a majority ruling, a three-judge panel at the Yugoslav war crimes tribunal said Gen. Zdravko Tolimir was the “right hand” of Bosnian Serb military chief Gen. Ratko Mladic, who is considered the chief architect of the murder of some 8,000 Muslim men and boys at the Srebrenica enclave in eastern Bosnia in July 1995.
