A styrofoam box was thrown at the vehicle driving head of Serbia's negotiating team Borislav Stefanovic during his visit to Pristina.

Officials of the Kosovo Police Service, whose vehicles escorted Stefanovic's automobile, confirmed that the incident took place as Stefanovic's car was leaving Pristina on the way to Caglavica.

According to the police, authorities have issued a warrant to the units in the field requesting that the individual who threw the box from the truck parked by to the road and the truck's owner should be taken in.

After a brief visit to the U.S. Embassy upon his arrival in Pristina, Stefanovic and his associates left for Laplje Selo, where he is supposed to confer with political representatives of local Serbs.

The Kosovo police used tear gas to disperse the crowd that gathered in front of the government building in Pristina to protest the talks between head of Belgrade's negotiating team Borislav Stefanovic and Kosovo officials.

The protesters were pushed back from the entrance, but continued throwing rocks at the police. The police managed to push the protesters toward smaller streets in Pristina, but they are still not leaving.

The demonstration started in front of the Kosovo government building, where supporters of the Self-Determination movement protested Stefanovic's visit. The protestors tried to break through the gate of the government building, but were stopped by police.

Tadic: Violence not helpful   

In regard to yesterday’s violence in Pristina during the working visit of Head of the Serbian negotiating team Borko Stefanovic, President Boris Tadic said that violence does not contribute to the resolving of problems between Albanians and Serbs.

Serbia must now react calmly and we should continue to participate in the dialogue extremely rationally in order to solve problems, Tadic emphasized in his statement to the Tanjug news agency.

He pointed out that problems in the territory of the West Balkans need to be addressed. T

he problem of Kosovo and Metohija must be resolved in a peaceful fashion, which does not mean that Serbia gives up on its legitimate national interests, but at the same time, we must understand the natural needs of the Albanian population, concluded the President.
