Marko Đurić was seized by special police officers who fired stun grenades to disperse crowd.

Air raid sirens have rung out in Serb-dominated northern Kosovo after special police fired stun grenades in a raid to detain a senior Serbian official, raising fresh tensions in the region.

Marko Đurić, head of Belgrade’s office for Kosovo and Metohija, was seized in the town of North Mitrovica by balaclava-clad and rifle-wielding members of Pristina’s ROSU police, who fired what appeared to be stun grenades to clear a crowd of angry Serb civilians. Inside the building, people ducked for cover as the police entered the hall where Đurić was speaking and led him away.
