Pristina - An explosive device was thrown Friday evening at the Pristina office of the internationally-appointed administrator for Kosovo, local police said.

Several cars were damaged and windows were smashed, but no one was injured in the attack, police spokesman Veton Elshani told Deutsche Presse-Agentur dpa.

The attack was against the office of the UN-appointed International Civilian Representative, tasked with overseeing United Nations settlement proposals for the region. The representative also acts as the European Union's Special Representative for the region.

Tensions are high in Kosovo, where its leaders have been having marathon talks with representatives of the United Nations and European Union over a revised plan for deploying Eulex, the EU mission in Kosovo.

Pristina opposes a so-called "six-point plan," out of concern that it could lose control over northern parts of Kosovo that are heavily populated by Serbs.

The plan, modified to offer Serbia some concessions, puts the Serb-dominated north of Kosovo under a UN command, while Eulex would administer the rest of the country. Pristina says the plan would mean de facto partition of Kosovo.

Kosovo declared independence from Serbia in February and was recognized by most of the EU and United States. (dpa)
