The Polish border service has reported about felled trees, sections of a fence and barbed wire on the border with Russia, according to Radio Poland's Russian-language service.
"We do not know why these abatises [a field fortification consisting of an obstacle formed of branches of trees laid in a row] are needed. Work has been underway for some time, but we do not know what this fence is being built for and what its function will be," warrant officer of the Warmia Mazury Border Service Anna Lusnya said, Radio Poland reported.
