Some protesters have started to gather on Sunday near the border crossing between Kosovo and Serbia, Jarinje, on the side of the Serbian territory, in support of the local Serbs who have erected barricades in the north of Kosovo.
Serbian police have created a cordon near the border.
The call for protest was made by right-wing groups, such as the "National Patrol", and it was called for other supporters from Serbia, Montenegro and the Republika Srpska e Bosnia-Herzegovina to join the organization.
Among them is Damjan Knezhević, head of the unofficial far-right group "National Patrol" from Serbia.
The "National Patrol" is known for its actions against immigrants, for glorifying Serbian war criminals and supporting Russia in its war in Ukraine.
The organization is linked to the far-right group "Rusov" and the Russian paramilitary group "Vagner", which it recently visited in Russia.
In some images published on online platforms, protesters are heard insisting to approach the border point, where troops of the NATO mission, KFOR, are seen.
