Tension escalates as Serbia threatens armed intervention in Kosovo again.

Serbia has threatened to intervene militarily in Kosovo if NATO-led peacekeepers fail to protect minority Serbs from what Belgrade called the terrorist threat of Kosovo’s ethnic Albanian authorities. Serbia has put its troops on the border with Kosovo on the highest state of alert amid a series of recent clashes between Kosovo Serbs on one side and Kosovo police and NATO-led peacekeepers, known as KFOR, on the other. Both Serbia and Kosovo are seeking EU membership, and need to normalize their relations to do so.
