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. Tensions flared anew last month after Kosovo police seized local municipality buildings in northern Kosovo, where Serbs represent a majority, to install ethnic Albanian mayors who were elected in a local election that Serbs overwhelmingly boycotted.
