A 130-mile long fence is being built on the border of Poland with Russia's exclave of Kaliningrad to prevent illegal crossings in what the country fears could become another migration crisis.
Defence Minister Mariusz Blaszczak, 53, announced the decision on Wednesday amid concerns in Warsaw that Russia plans to orchestrate an influx of migrants in the NATO country.
This comes following a recent decision by Russia’s aviation authority to launch flights from the Middle East and North Africa to Kaliningrad.
