HEAVY FIGHTING NORTH OF SARAJEVO, U.N. SAYS

SARAJEVO, Oct 4 (Hina) - Heavy fighting was reported between the Bosnian government army and Serb forces in the Mount Cemerno area, 50 km north of Sarajevo, a press conference at the UN headquarters in Sarajevo said today. UN military observers counted more than 2,200 artillery, tank and mortar impacts. They believed the Serb forces launched a major offensive in a bid to regain control of positions they had lost to Moslem-led Bosnian government troops in August. UN military observers also reported continued fighting in western Bosnia. UNPROFOR spokesman Tim Spicer said that Bosnian army forces fired four mortar rounds on Vojkovici, a Serb village southeast of Sarajevo, inside the weapons exclusion zone. Spicer said Moslem troops yesterday deliberately opened fire on a UN bulldozer in Sarajevo's Dobrinja district. The bulldozer took several bullets fired from a heavy machine-gun and a French UN armoured vehicle returned fire. (hina) mm vm 041353 MET oct 94
