Serbian forces detained three Kosovo police officers on Wednesday, but officials in Kosovo and Serbia offered different locations for the arrests, accusing each other of crossing the border illegally, Reuters reported.

Prime Minister of Kosovo Albin Kurti demanded the release of three officers. According to him, they were detained 300 meters inside the territory of Kosovo near the border with Serbia.

“The introduction of Serbian forces into the territory of Kosovo is aggression and aimed at escalation and destabilization,” Kurti wrote on his Facebook page.

But Serbian President Aleksandar Vucic said the three were arrested “up to 1.8 kilometers away” inside Serbian territory near the village of Hnilica. He also accused Kurti of fueling the conflict.

“We are at a crossroads, whether we will have peace or not… and there is one person in the Balkans who wants to ignite a conflict at any cost, and that is Albin Kurti,” Vucic said on a live TV show.
