NATO confirmed today that it approved additional forces to resolve the current situation in Kosovo, but did not specify the number and did not say from which countries.

Clashes broke out last weekend between police and armed Serbs.

Kosovo President Vjosa Osmani accused Serbia and its president Aleksandar Vucic of being responsible for the attack on Kosovo police in the north of the country, saying in an interview with Reuters on Thursday that Kosovo was "under attack".

Three dozen armed Serbs attacked the Kosovo police in the village of Banjska on Sunday, after which they barricaded themselves in a monastery of the Serbian Orthodox Church.

Three Serbs and one Kosovo policeman were killed, and so far three people have been charged with participating in the attack.

Serbia, which does not recognize the independence of its former province, accuses Kosovo of inciting violence by harassing ethnic Serbs.
