SERBS STILL DETAIN FIVE HUMANITARIAN WORKERS IN PRISON

SARAJEVO, May 7 (Hina) - Several strong detonations echoed in Sarajevo overnight, but UN officials described the situation in Bosnia's capital as rather calm. Three explosions rocked the confrontation lines between Serb- occupied suburb 'Grbavica' and the unoccupied part of the city at about the midnight. An explosion of mortar round echoed in Sarajevo's 'Stari Grad' municipality at 08:30 am Sunday. Serb aggressors opened machine-gun fire at the road via Mount Igman overnight. Serbs situated in Donji Kotorac inside the heavy arms exclusion zone around Sarajevo, fired ten mortar rounds yesterday. UN radars registered the source of the rounds, but could not find out the targets of the Serb shelling. No casualties have been reported in Sarajevo in the last 24 hours according to UN military observers'' reports. The detained five workers of "Pharmaciens Sans Frontier", whose release was announced by Serbs on Saturday, are still at Serb prison in the Lukavica military barracks. UN officials could not know why the liberation of the humanitarian works has been postponed. Since the workers are members of non-governmental relief agencies, UN officials are not authorized to ask for them. According to some sources, the action of realise of the five humanitarian workers is being conducted through the mediation of the French Embassy in Sarajevo. (hina) mms 071247 MET may 95
