OK, is it the Serbs or Albanians who are behind this one? From the AP, July 2:

PRISTINA, Serbia-Montenegro — At least three blasts rocked the centre of Kosovo's capital late Saturday and one targeted the UN mission headquarters. At least three UN vehicles were set ablaze in the parking lot of the mission headquarters. There were no immediate reports of any injuries after at least two near-simultaneous blasts, said Hua Jiang, chief UN spokeswoman.

The second blast happened near the building of the Organization for Security and Co-operation in Europe, the OSCE, which is some 100 metres down the road from the UN compound. The third blast went off near the Kosovo government building which also houses the occupied Serbian province's legislature, said Jiang. She did not say what caused the blasts. Police sealed off the areas after the explosions.

Kosovo has been administered by the UN mission and occupied by NATO troops since 1999.
