REBEL SERBS OPEN MORTAR FIRE ON SUNJA

ZAGREB, May 23 (Hina) - Serb paramilitary forces last night opened small arms and mortar fire on Sunja, about 70 km southeast of Zagreb, the Croatian army said in a statement. Rebel Serbs breached the ceasefire at 22.05 hours when they launched an infantry attack on the town's railway station. Shortly afterwards they fired six mortar rounds on residential buildings in the centre of the town, setting one house alight. At 22.35, a group of Serb terrorists, opening small arms fire, attempted to get closer to the railway station, situated in a UN-supervised buffer zone, the statement said. The Croatian army vehemently protested to UNCRO officials about the attack. (hina) vm 231711 MET may 95
