Serbian and Kosovo Albanian leaders failed in talks on Tuesday to break a deadlock over the breakaway Serb province, but agreed to hold three days of negotiations next week ahead of a December 10 deadline to try to reach a compromise, mediators said.

Both sides stuck to their existing positions, with Kosovo Albanian negotiators rejecting a Serb offer of broad autonomy and insisting on EU-supervised independence, a statement issued by a team of European, U.S. and Russian mediators said.

The next round the first to last more than a day will take place in Baden, Austria from November 26 to 28, it said.
