BOSNIAN ARMY LIFTS BLOCKADE OF U.N. BASE AT TUZLA AIRPORT

SARAJEVO, Jan 23 (Hina) - The situation in most parts of Bosnia- Herzegovina has been calm in the last 24 hours, with ceasefire violations in the north-western enclave of Bihac. UN military observers recorded 30 detonations overnight in the Bihac area, in the villages of Klokot, Zegar and Vedro Polje. About 100 explosions were registered along the line of confrontation between the Bosnian Moslem-led government army and rebel Moslem and Croatian Serb forces east of Velika Kladusa. UN observers also reported that Serb forces fired two artillery shells in the Ribnica area in central Bosnia. UN spokesman in Sarajevo Gary Coward said the Bosnian government and Serb representatives resumed talks on opening supply routes in and out of Sarajevo. Bosnian government minister Hasan Muratovic and Serb negotiator Momcilo Krajisnik said after talks yesterday they were optimistic about reaching an agreement on "blue routes" soon. The blockade of a UN base at Tuzla airport was lifted yesterday after a Serb liaison officer left the base. The Bosnian government army had blocked the airport in protest at the presence of Serb liaison officer Slavko Guzvic. The Bosnian army Second Corps said Guzvic had been the commander of a Serb brigade before he became a liaison officer and was held responsible for artillery attacks on civilian targets in Tuzla.
