PRISTINA, Serbia (Reuters) - Serbian security forces have taken the Kosovo Albanian town of Junik, one of the last outposts of separatist rebels, Serb sources said on Sunday. "After taking control of the village of Voksa, Serb police have taken control over the village of Junik," a Serb security source told Reuters. Junik, a hill town in the far western reaches of Kosovo near the Albanian border, was reputed to be one of the last bastions of the separatist Kosovo Liberation Army (KLA), fighting for Kosovo`s independence from Serbia. Serb police had surrounded the town for about two weeks but in recent days, after the European Union condemned what it called "massive attacks" on Junik, the Serbs said they had held their fire. The fall of Junik would be a major blow to the KLA, which had taken loose control of up to half of Kosovo in an offensive which began six months ago but has been pushed back in a massive four-week-long drive by Serb security forces, backed by armour and aircraft. The Serbian offensive has contributed to the growing refugee problem in Kosovo, where 90 percent of the two million population is ethnic Albanian and an estimated 10 percent are now displaced from their homes and farms.
