Around two dozen soldiers of the KFOR peacekeeping force were injured in violent protests by ethnic Serbs in Kosovo in the village of Zvecan. Serbia and Russia have a long-standing partnership - and the Kremlin has repeatedly made accusations against NATO.
Serbian tennis star Novak Djokovic got involved in political events: "Kosovo is the heart of Serbia! Stop the violence," he wrote on a camera after his opening match at the Grand Slam tournament Roland Garros in Paris. Serbia, meanwhile, put its armed forces in high combat readiness.
