Skirmishes between gunmen and authorities in northern Kosovo were ongoing on Sunday, September 24, according to Prime Minister Albin Kurti, hours after a police officer had been killed when a patrol was hit by an ambush involving firearms and explosives.
The attack and ongoing firefight marks one of the gravest escalations in Kosovo in years, following months of mounting tensions and stalling talks between the government in Pristina and Serbia.
Kurti said at least 30 heavily armed gunmen were now surrounded by authorities near Banjska in north Kosovo and called for their surrender.
"There are at least 30 professional, military or police armed people who are surrounded by our police forces and whom I invite to surrender to our security agencies," said Kurti during a press conference.
Kurti added that the group was located in and around a monastery near the village of Banjska, where the patrol had been ambushed early Sunday.
The Serbia Orthodox Church confirmed that gunmen had stormed a monastery in Banjska, where pilgrims from the northern Serbian city of Novi Sad were staying.
"We can see armed people in uniforms... they are firing on us and we are firing back," Kosovo police official Veton Elshani told AFP by phone from Banjska.
Kurti's comments came hours after he called the ambush that killed one police officer and wounded another an act of terrorism and pinpointed the blame on the Serbian government.
"Organized crime with political, financial and logistical support from officials in Belgrade is attacking our country," Kurti wrote on social media.
Serbian President Aleksandar Vucic was set to address the media later on Sunday.
According to the Serbian government's office for Kosovo, the president's press conference would "debunk all the lies and hoaxes of Albin Kurti, the creator of chaos and hell in Kosovo."
Serbian state media outlet RTS later reported that the Jarinje and Brnjak border crossings between Serbia and Kosovo have also been closed following the incident.
The attack comes more than a week after talks between the leaders of Serbia and Kosovo centered on improving ties failed to make a breakthrough during EU-mediated negotiations in Brussels.
The EU has been trying for years to resolve the long-running dispute between the Balkan neighbors that has soured relations since their war more than two decades ago.
Brussels believed it had broken the logjam by hammering out a plan to normalize ties in March, but since then there has been minimal progress.
The EU's top diplomat Josep Borrell condemned Sunday's attack, calling the targeting of police "hideous".
"The responsible perpetrators must face justice," Borrell wrote on social media.
