Twenty-five NATO peacekeepers have been injured in a clash with Serbs protesting recent election results in northern Kosovo.
Since Friday, the peacekeepers, known as Kosovo Force (KFOR), have been assisting police in protecting four municipal buildings from ethnic Serb protesters in the north.
The tense situation in Kosovo developed after ethnic Albanian mayors took office in northern Kosovo's Serb-majority area following elections that the Serbs boycotted.
