Tensions remain high in Kosovo, the mostly Muslim enclave of Serbia, following the drowning deaths two weeks ago of three Albanian boys believed to have been chased into a river by Serbian men.

Some observers now say Albanians instigated the violence against the Serbs, who are a minority in Kosovo. NATO peacekeepers recently left the area where the violence hit. NPR's Emily Harris reports.
