DERANGED U.N. OBSERVER KEY SUSPECT IN U.N. KILLING IN BOSNIA

SARAJEVO, Feb 3 (Hina) - A UN military observer in Bosnia was believed to have been killed yesterday by a colleague in a freak moment of mental derangement, the UN said. UN spokesman Gary Coward told reporters in Sarajevo today that the military observer was killed near the eastern town of Rogatica, but circumstances surrounding the killing were unclear. Coward was unable to disclose any details on the incident but said it was unofficially believed that the UN officer suffered from certain psychological problems and that he killed his colleague in a moment of madness. The two men set out from Gorazde to Sarajevo but only one of them was found in their vehicle when it was fired at after failing to stop at a Serb checkpoint in Rogatica. The body of the other observer was later discovered by the bank of the Drina river, Coward said. Coward reported another serious incident which happened at Hrasnica near Sarajevo on Tuesday when Bosnian government army soldiers held up a Russian UN personnel carrier and then arrested and manhandled the five-member Russian crew. UNPROFOR had filed a severe protest to the Bosnian government over this incident, Coward said. (hina) sd vm as 031549 MET feb 95
