TEN SHELLS HIT DOWNTOWN BIHAC

SARAJEVO, May 17 (Hina) - Serb forces this morning launched an artillery attack on the UN-designated safe zone of Bihac in north- western Bosnia. According to UN military observers, downtown Bihac was hit by ten cannon shells. The observers did not know what were the consequences of the attack, but Sarajevo radio spoke of several casualties and considerable material damage. According to UN sources, the Bosnian army 5th corps was advancing on Serb-occupied Bosanska Krupa, seizing control of the Krupa road and the Grabez Plateau. The UN assumed that today's attack on Bihac had been launched in retaliation for Serb losses on the Grabez plateau. The Bosnian army yesterday attempted to break through Serb lines on Mt Bucimici, west of Bosanska Krupa. The UN was unable to say anything as to the outcome of this operation, but did count 337 detonations in the area. The Velika Kladusa area was comparatively calm. (hina) mm as 171315 MET may 95
