 NATO peacekeepers and local police forces guarded municipal buildings in Kosovo on June 1. In the town of Lyapsavik, NATO soldiers behind barbed wire barriers guarded the municipal building where the ethnic Albanian mayor has remained since entering it on Monday amid Serb protests. Following violent clashes with Serb protesters on Friday after Kosovo Albanian mayors tried to enter office, the mayor in Lyapsavik, Lulzum Hedemi, entered the municipal building at 0530 local on Monday before Serb protesters had been able to gather again. In the town of Zubin Potak, Kosoven police forces could be seen standing by the town hall, protecting it from possible clashes. Many locals were starting to gathered, but protesters were peaceful. Days of unrest in northern Kosovo have prompted NATO to send additional troops to stave off violence after the mayors were installed last week, despite an official 3.5% election turnout.
