Pristina, Serbia-Montenegro ? At least three blasts rocked Kosovo’s capital Saturday, and one targeted the U.N. mission headquarters.

An Associated Press reporter saw at least three U.N. vehicles set ablaze in the parking lot of the U.N. mission headquarters in Pristina.

There were no immediate reports of any injuries after at least three near-simultaneous blasts, said Hua Jiang, chief U.N. spokeswoman.

The second blast detonated near the building of the Organization for Security and Cooperation in Europe, the OSCE, which is a block away from the U.N. compound.

The third blast went off near the Kosovo government building which also houses the province’s parliament and damaged it slightly, said Jiang. She did not say what caused the blasts.

Kosovo has been administered by the U.N. mission and patrolled by NATO-led peacekeepers since 1999 after the alliance’s bombing of Serb forces waging a crackdown on separatist ethnic Albanians.

The province remains disputed between its ethnic Albanian majority who want it to become independent, and Serbs demanding it remain part of Serbia-Montenegro.
