A former Yugoslav general has been sentenced to eight years in prison for his role in the 1991 shelling of the Croatian city of Dubrovnik.

The U.N. war crimes tribunal in The Hague

Monday found General Pavle Strugar guilty of not doing enough to prevent attacks on civilians and of not punishing subordinates responsible for the shelling. He was acquitted of four other war crime charges, including murder.

Strugar commanded Yugoslav forces during the December 6, 1991 shelling that destroyed much of Dubrovnik's historic old city and killed at least two civilians.

Meanwhile, the former head of the Bosnian army has gone on trial at court.

Prosecutors say Sefer Halilovic commanded troops who murdered dozens of Bosnian-Croat civilians in an operation code-named "Neretva 93." The mission took place in September 1993, and was aimed at retaking territory controlled by Bosnian-Croat forces, and to end the blockade of the city of Mostar in Bosnia-Herzegovina.

Mr. Halilovic has pleaded not guilty. He is the highest ranking Bosnian Muslim commander to face charges at the International Criminal Tribunal for the former Yugoslavia.

Earlier this month, the war crimes tribunal convicted two Bosnian Serb army officers for their roles in the 1995 massacre of thousands of Muslims at in the Bosnian enclave of Srebrenica.
