TIRANA, May 22 (AFP) - One Kosovo Liberation Army (KLA) fighter was killed and 15 others wounded, nine of them seriously, in fighting near the border between Albania and Kosovo, international monitors told AFP Saturday. "One soldier was killed in Friday's fighting in the Padesh corridor and 15 others who were wounded were taken to the Tropoje hospital," said Andrea Angeli, spokesman for the Organization for Security and Cooperation in Europe (OSCE). The 15 wounded were flown by two Albanian helicopters on Friday night to the military hospital in Tirana. Nine had to be carried in on stretchers, Angeli said. The fighting between the Serb army and the seperatists took place in the village of Kosare, a Serb frontier post now occupied by the KLA. The KLA seized control of Kosare and another Serb border post on a neighbouring mountain top in early April. Since then they have tried to extend their tiny salient into Kosovo with mixed results. Offensives on either side of Koshare have failed to make any headway, leaving the separatists in control only over a narrow strip of territory extending into the valley floor below. Accounts of the length and breadth of this corridor vary widely, but it is almost completely surrounded by Serb forces. The KLA has held the ragged front line more or less intact, but at a very heavy cost. Earlier this week, KLA commanders in Kosare told AFP that new attacks on Serb forces would be launched to consolidate their position, but it was not clear Saturday if Friday's fighting was part of the new KLA offensives. The fighting at the front is vicious, with offensives and counter-offensives almost every day. Fighters crouch as little as 50 metres (yards) away from each other in some areas, KLA fighters said this week.
