Polish Prime Minister Mateusz Morawiecki called the migrant crisis on the Belarusian-Polish border, the EU's eastern frontier, the "greatest attempt to destabilize Europe" since the Cold War.

Belarus President Alxander Lukashenko "launched a hybrid war against the EU," Morawiecki said on Twitter, calling it the "greatest attempt to destabilize Europe in 30 years."

The migrant crisis is escalating

Yesterday, Poland accused Belarus of changing its tactics in dealing with the migrant crisis between the two countries. "Now, migrants use slightly different methods. Smaller groups of people try to force the border in multiple spots," Polish Defense Minister Mariusz Blaszczak said.

Hundreds of migrants have been attempting to cross the border from Belarus to Poland for months, but tensions picked up after Poland deployed 10,000 troops near the border with Belarus following the flow of migrants into its territory.

Western governments accused Lukashenko of luring migrants to his country and sending them across the border to the EU in retaliation to EU sanctions.

Lukashenko advised the West, following a government meeting on November 11, to think carefully before threatening Belarus with new sanctions and closing its borders, threatening to cut off gas supply to Europe.

Regarding these development, Russian Foreign Minister Sergei Lavrov had said the West bears responsibility for the migrant crisis caused by its actions in the Middle East, calling for a resolution of the migrant crisis on the borders in compliance with international humanitarian laws.
