NATO and the European Union scrambled to calm tensions between Kosovo and Serbia after a weekend flare-up that some politicians and experts fear could be used by Russia to spark more instability in Europe.
On Sunday, NATO forces tasked with securing Kosovo threatened to intervene to prevent a bureaucratic dispute over cross-border trade from escalating beyond a war of words between Kosovo and Serbia. Kosovar authorities said shots were fired Sunday during a standoff between Kosovar police and ethnic Serbs near the Serbian border but no one was hit.
