The Polish military set up a barrier using barbed wires along Poland’s border with Russia’s Kaliningrad, near the village of Wisztyniec on Thursday.
In the footage, soldiers could be seen setting up the razor-wire fence, which will be 2.5-metre (8.5 ft) high and 3-metre (9.8 ft) deep once finished, according to Poland’s Defence Minister Mariusz Blaszczak.
The barrier along the border with Russia’s Kaliningrad region is being built over security concerns in connection with the Ukraine conflict and fears over possible illegal border crossings of migrants, as they happened last year, when thousands of refugees tried to cross the border to Europe from Belarus. Warsaw has accused Minsk of using migrants as a weapon to destabilise Europe, a claim Minsk has repeatedly denied.
According to Polish authorities the situation at the border has been calm, however, with no illegal crossings reported in October.
