The NATO-led peacekeeping force in Kosovo, KFOR, has increased the number of its troops injured in violent clashes with ethnic Serbs to 30.
The Serbs had tried to take office in one of the municipalities in northern Kosovo, where Albanian mayors took office last week.
Tuesday’s statement said 11 Italian and 19 Hungarian soldiers “suffered multiple injuries including fractures and burns from improvised explosive devices.”
It added that three Hungarian soldiers were “injured from the use of firearms” but their injuries were not life-threatening.
Some of the clashes occurred in the municipality of Zvecan, 45 km (28 miles) north of the capital Pristina.
“Both parties must take full responsibility for what happened and prevent further escalation instead of hiding behind false narratives,” said KFOR commander Maj. Gen. Angelo Michele Ristuccia.
Ethnic Serbs want to gather again on Tuesday.
High alert
Serbian President Aleksandar Vucic spent the night with his troops on the Kosovo border.
On his orders, they were placed on high alert last week. Vucic said 52 Serbs were injured in the clashes, three of them seriously.
According to the Kosovan police, four people were arrested.
The violence was the latest incident since the weekend, when ethnic Serbs in northern Kosovo tried to prevent recently elected Albanian officials from entering city buildings.
Kosovo police used tear gas to disperse the crowd and let the new officers into the offices.
Serbia has put the country’s military on high alert and sent more troops to the border with Kosovo.

The United States and the European Union have stepped up efforts to resolve the Kosovo-Serbia dispute amid fears of further instability in Europe due to the Russian war in Ukraine.

“Ultra-nationalist Serbian graffiti on NATO vehicles is a grim memory in Kosovo. We stand for peace and security,” Kurti said after the meeting.
Quint ambassadors will meet with Vucic, and he is also meeting with Russian and Chinese ambassadors to show support for his policies.
Ethnic Serbs in Zvecan, Leposavic, Zubin Potok and Mitrovica, four northern municipalities, held elections last month that were largely boycotted by ethnic Serbs.
Only representatives of ethnic Albanians or other smaller minorities were elected to mayoral offices and assemblies.
The conflict in Kosovo erupted in 1998 when separatist ethnic Albanians rebelled against Serbian rule and Serbia responded with brutal crackdowns.
About 13,000 people, mostly ethnic Albanians, died.
NATO military intervention in 1999 finally forced Serbia to withdraw from the territory.
Washington and most EU countries have recognized Kosovo as an independent state, but not Serbia, Russia and China.
