 Local Serbs block roads in Northern Kosovo as tensions flare up. Estnick Serbs in Northern Kosovo have blocked the roads on the border with Serbia, amid heightened tension in the region. Draw footage circulated in the media shows roads blocked across Rudari and North Mitrovica, across Northern Kosovo. Large trucks and vehicles have been used to create the roadblocks. The incident comes amid heightened ethnic tension between Kosovo and its Serbian minority in the north. Since December 10, Serbs in the northern Kosovo have exchanged fire with police and erected over a dozen roadblocks in and around Mitrovica. This comes after the arrest of a former Serbian police officer earlier. Serbia has denied reports that it wants to destabilize Kosovo, saying that it only protects the region's Serb minority.
