International mediators said on Friday that they had failed to broker an agreement between Serbia and Kosovo over the future status of the province, leaving it up to the UN Security Council to rule on the deadlock over its demand for independence.

The so-called troika – the European Union, US and Russia – said in a final report: “After 120 days of intensive negotiations, the parties were unable to reach an agreement on Kosovo’s status. Neither side was willing to yield on the basic question of sovereignty.”
