Kosovar Prime Minister Hashim Thaci on Friday asked the United Nations and NATO to impose order in the tense, Serb- dominated north of Kosovo, according to DPA. Thaci, with President Fatmir Sjediu, asked the UN administrator in Kosovo, Joachim Ruecker, to "urgently impose law and order" in the hotspot town Mitrovica. The two Kosovo leaders were to meet the NATO Secretary General Jaap de Hoop Scheffer, scheduled to arrive later Friday for his first visit to Kosovo after the province declared independence. Hours earlier, several hundred Kosovo Serbs broke through an international police cordon in the divided Mitrovica and broke into the UN municipal court building. "There was a joint request ... that UN and NATO law-enforcing agencies urgently expel hooligans from the building," Thaci and Sejdiu said in a statement after meeting Ruecker. Serbs, who dominate the northern section of the town and about a fifth of Kosovo's territory to the north of it, have been protesting daily since Pristina declared independence from Serbia a month ago. Albanians are the overwhelming majority elsewhere in Kosovo.
