“The NATO-led KFOR mission is closely monitoring the situation and stands ready to intervene if stability is threatened,” the mission said in a Twitter statement.

The mission noted that the overall security situation in the northern municipalities of Kosovo remains tense.

Earlier, Serbian media reported that air raid sirens sounded in the northern part of the unrecognized Kosovo - they, as well as shots, were reported by residents of the border area.

Later it became known that the police of the unrecognized Kosovo closed the Brnjak checkpoint in the north of the province.

It was also reported that special forces of the police of the unrecognized Kosovo moved out of Pristina to the north of Kosovo and Metohija.
