Nenad Arsic pleaded not guilty to committing a war crime as he went on trial on Tuesday at Pristina Basic Court.
The indictment alleges that Arsic, as a reservist member of the Serbian police, committed the crime on May 21, 1999 during a police operation against Kosovo Albanian civilians in Pristina's Emshir neighbourhood.
He made a guest appearance last night on the "Upitnik" talk show, where he said that he would continue to fight for Kosovo and the Serb people with all his heart and energy.
