Former Bosnian Serb leader Radovan Karadzic has been convicted of genocide and war crimes during the 1992-95 war, and sentenced to 40 years in jail, the BBC repots.
UN judges in The Hague found him guilty of 10 of 11 charges, including genocide over the 1995 Srebrenica massacre.
Karadzic, 70, is the most senior political figure to face judgement over the collapse of Yugoslavia.
His case is being seen as one of the most important war crimes trials since World War Two.
He had denied the charges, saying that any atrocities committed were the actions of rogue individuals, not the forces under his command.
The trial, in which he represented himself, lasted eight years.
His lawyer said he would appeal, a process that could take several more years.
