U.N. PEACEKEEPERS AND SERB FORCES EXCHANGE FIRE NEAR SARAJEVO

SARAJEVO, April 7 (Hina) - UN peackeepers and Bosnian Serbs exchanged fire several times overnight in the Sarajevo area. A Serb mortar attack on a UN observer post prompted the UNPROFOR commander to call in NATO war planes to establish where the attack had been lauched from. The planes buzzed the Sarajevo area but did not engage in combat actions. French UN soldiers responded to a Serb attack on a Mount Igman road, UNPROFOR spokesman Pierre Chavancy said in Sarajevo today. Serbs used a 20-mm cannon in the attack on UN vehicles on the road, and 'blue helmets' returned fire. The exchange lasted from 10.45 p.m. until midnight. + A UN minibus was also on the road at the time of the attack, but so far there have been no reports of casualties. At around 9 pm Serbs fired three shells at central Sarajevo and another two at Kosevo, UN observers said. Kosevo hospital authorities confirmed that two civilians had been wounded in these attacks. Chavancy said that a Bosnian army soldier and a civilian had been killed and two other civilians had been wounded in yesterday's Serb mortar attack on the Sarajevo suburb of Hrasnica. He added that the attack had been carried out from the heavy weapons exclusion zone around the city. (hina) jn rm vm 071304 MET apr 95
