The United Nations' mission in Kosovo is calling on Serbia to stop interfering in Serb areas of the territory following the declaration of independence issued by leaders of its ethnic Albanian majority.
The mission is in charge of maintaining order in the former Serbian province, until European Union replacements are deployed as expected in the coming weeks.
U.N. spokesman Alexander Ivanko in Pristina challenged Serbian officials Wednesday to "put their money where their mouth is" and respect the U.N. mandate in Kosovo under Security Council resolution 1244.
The spokesman also called on Belgrade to cooperate in re-establishing customs points on Kosovo's northern border. Several checkpoints were set afire last month by Serbs angered by Kosovo's February 17 declaration of independence.
Serbian Foreign Minister Vuk Jeremic asked U.N. administrators Tuesday to halt the transfer of power.
