Serb leaders in the north of Kosovo say they have cut all contact with the province’s UN mission and the ethnic Albanian authorities.Responding to a spate of shootings they blame on Albanians, the leaders declared a state of emergency. They also called for the return of Serbian police, who were forced to leave in 1999. It was the latest sign of growing resistance by Kosovo’s Serb minority, which has raised fears it could make a unilateral bid to partition the province. The final status of Kosovo is currently the subject of UN-led talks that began in February. The ethnic Albanian majority is pushing for independence from Serbia this year. That’s a move favoured by Western powers, who have ruled out partition, fearing it could be a trigger for fresh ethnic violence.
