A former Yugoslav army chief of staff has pleaded not guilty to 13 counts of war crimes and crimes against humanity before the United Nations tribunal in The Hague.

General Momcilo Perisic appeared in court Wednesday to face charges that troops under his command attacked Zagreb, the Croatian capital, and committed atrocities during the Bosnian conflict between 1992 and 1995.

The charges include the massacre of more than 7,000 Muslim men and boys by Bosnian Serb troops following their capture of the Muslim enclave of Srebrenica.

General Perisic surrendered to the court Monday.

He said last week that appearing before the tribunal was the best way to defend his honor and the reputation of the army.
