NATO troops have demolished a barricade built by local Serbs in northern Kosovo.
Tensions have been running high this week as Kosovar Serbs protest against the Pristina government’s attempts to control the border.
Kosovo is largely ethnically Albanian, but 60,000 Serbs who live in the north pledge their allegiance to Belgrade.
Serbia pulled out of EU-backed negotiations on Wednesday after clashes left 16 Kosovar Serbs injured.
The talks had been aimed at settling differences over a trade dispute and Serbia’s refusal to recognise Kosovo.
Kosovo broke away from Serbia in 2008 and has since been recognised by at least 80 countries.
