Serbian president Boris Tadic and his Kosovo counterpart Atifete Jahjaga condemned the clashes and appealed for calm, saying dialogue between Belgrade and Pristina was the only way for peaceful solution.
The violence broke out as NATO soldiers stationed in Kosovo (KFOR) removed a roadblock in Jagnjenica, set up by local Serbs in protest over the placing of Kosovo police and customs at two northern border crossings, Brnjak and Jarinje.
Belgrade opposes Kosovo independence, declared by majority Albanians in 2008. Kosovo's minority Serbs, who make majority population in the north, have been blocking roads for over four months.
“I call on KFOR officials, EULEX (European Union mission) and Serb political representatives to calm the situation immediately and to secure complete freedom of movement strictly through dialogue and without violence,” Tadic said in a statement.
He called on local Serbs to prevent “extremists” in their ranks, who “threaten the security of our citizens and international officials in Kosovo. The lives of our citizens and representatives of international institutions must be saved at all costs,” he added.
Appealing for calm, Jahjaga called on Belgrade to “stop rendering support to criminal structures” in northern Kosovo and said “criminals who attacked KFOR soldiers should be discovered and punished”.
KFOR said in a statement late on Monday, 23 of its soldiers were injured in day-long clashes. “The protestors could not be called as peaceful demonstrators at all, but as violent and criminal,” it said.
KFOR used teargas, rubber bullets and water cannons against protesting Serbs on Monday. But it warned that “in life threatening situations like this KFOR soldiers will respond with all proportionate means”.
Despite cold, local Serbs spent the night manning barricades, warmed by bon fires, as KFOR soldiers in full riot gear stood by. Local Serb leaders are due to meet with KFOR representatives later today in an effort to resolve the crisis.
