The U.N. war crimes tribunal in The Hague has convicted two Bosnian Serb army officers of complicity in the 1995 massacre of thousands of Muslims.

Colonel Vidoje Blagojevic was found guilty of aiding and abetting genocide in the deaths of more than 7,000 unarmed Muslim men and boys at Srebrenica in Bosnia-Herzegovina. He was sentenced to 18 years in prison.

Major Dragan Jokic was found guilty of aiding and abetting murder, and of extermination and persecution, and was sentenced to nine years.

Both men had pleaded not guilty.

The 1995 massacre occurred after Serbs captured Srebrenica, which the United Nations had declared a safe area.

Bosnian Serb authorities acknowledged for the first time last year that there had been a massacre.
