Russia has begun to erect a fence on the border with Poland and the Kaliningrad region, reports Polskie Radio.
The construction work has been going on for over a month. The brush fence and barbed wire appeared from the Russian side.
"We do not know why we need this fence. The work has been underway for some time, but we do not know why they are building this fence, and what its function is", said Anna Lusnya, Ensign of Warmia and Mazury Border Service.
