PRISTINA, Serbia-Montenegro -- Three people were gunned down and at least four others wounded when unknown assailants opened fire in western Kosovo late Saturday, an official told AFP.

The incident happened after 10 pm (2000 GMT) in the town of Pec, some 85 kilometers (53 miles) west of Kosovo's capital Pristina, Andrea Angeli, spokesman for the UN mission in Kosovo, said.

"There was machinegun fire in the center of Pec. Some of the victims and those wounded were sitting in nearby cafes in what is usually a busy night," Angeli said.

A 14-year-old girl was among the victims. The others were a 24-year-old female and a 30-year-old male. All of the victims were Kosovo Albanians, but their names have not been released pending the notification of their families.

Angeli said no arrests were made and that it was not clear who or what was the target of the attack. The wounded were transported to the Pristina hospital, two of them in critical condition.

The UN police in Pec cordoned off the area and an investigation was ongoing.

Kosovo has been under UN administration since NATO bombed Yugoslavia to force the withdrawal of Serbian troops in early 1999.
