Talks between Serbia and Kosovo are under way in the Belgian capital, Brussels, under the aegis of European Union.
Catherine Ashton, the EU foreign affairs head, hosted the Serbian and Kosovo prime ministers, Ivica Dacic and Hashim Thaci, as they try to come up with a deal to ease long-running tension between the estranged neighbours.
Both sides must agree on just who has authority over Serbs living in northern Kosovo.
In 2008, Kosovo declared independence from Serbia, but the Serbian government has refused to recognise the split.
Settling the impasse would help put both countries on the path to EU membership.
