Pristina  - A grenade slammed into the barracks of the Kosovo Security Force (KSF) Thursday night, a day after the fledgling army of the volatile new country was formed.

Police in Pristina said nobody was injured in the explosion in the attack in Pec, a town in western Kosovo. A grenade, apparently fired from a launcher, hit the roof of one of the KSF buildings.

Police did not speculate on the motives for the attack and were still investigating Friday morning.

The lightly-armed KSF, with 2,500 regular and 800 reserve troops, replaced the unarmed Kosovo Protection Corps on Tuesday.

Belgrade and the minority Kosovo Serbs continue to reject Kosovo's independence, which Pristina declared 11 months ago. Serbs see the KSF as an instrument of pressure by the dominant Albanian majority. (dpa)
