A row over car number plates seems an unlikely reason for placing troops on alert and falling out with international partners. But Serbia and Kosovo are currently doing precisely that.
Kosovo’s insistence that ethnic-Serb residents must surrender their Serbian-issued licence plates is straining relations with its main international supporters, the EU and the United States.
Nato’s Kfor peacekeeping troops are increasing patrols in case of any incidents. And Serbia’s defence minister says its troops are standing by “to protect all the citizens of Serbia, including the Serbs in Kosovo”.
Soon after midnight on Tuesday, Kosovo police began handing out their first written reprimands, as the deadline for the number-plate swap expired. The first recipient was a woman arriving from Serbia through the checkpoint at Jarinje, in the north of Kosovo.
The police notice warned that she must remove the Serbian-issued number plate from her car by 21 November, or face a fine. But the driver demurred, saying she would wait to hear from Serbia’s government before making any changes.
