UN officials in Kosovo have received threatening letters from the Albanian National Army which are believed to signal a new campaign against the international administration of Serbia’s southern province. UNMIK staff have been told to report threats to the security service, say Belgrade media. But the Kosovo Protection Corps, the home guard formed by the transformation of the former guerrilla Kosovo Liberation Army say they are not surprised by the group’s threats. Corps commander Agim Ceku says that the Albanian National Army has organised bomb attacks on the UNMIK headquarters and attempted to assassinate President Ibrahim Rugova. The director of the Forum for Ethnic Relations told media that the lack of cooperation between Kosovo Albanian politicians and UN officials has opened a space for extremist activities. “It’s obvious that the Albanian movement is mixing violence with politics. When the politics isn’t working they resort to violence,” said Dusan Janjic, adding that UNMIK would not cave in to threats.
