Serbia has put its army at highest level of combat readiness after increasing tensions with Kosovo.

President Aleksandar Vucic has accused that Kosovo is preparing "an attack" on ethnic Serb areas in north of country.

However, the government in Pristina has made no comment about the allegations.

Serbia does not recognise Kosovo as an independent state, nor do the ethnic Serbs who live there.

Belgrade accuses Kosovo of plotting "terrorism against Serbs" in areas where some 50,000 ethnic Serbs live.
