Poland's defense minister has ordered the construction of a temporary barrier along the border with Kaliningrad, AP reports.

The move comes as Warsaw suspects Russia plans to facilitate illegal border crossings by Asian and African migrants.

Defense Minister Mariusz Blaszczak said the border must be secured to make Poland feel safe. He said he has authorized the construction of a temporary barrier along the 210-kilometer border. Work will begin on Wednesday.

Poland's border with Belarus was the scene of a serious migration crisis last year, with large numbers of people crossing the border illegally. Poland has erected a steel wall on its border with Belarus.
