Migrants and refugees caught up in Belarus-EU "hybrid warfare" are freezing to death in no man's land

Sokółka, Poland — As you approach the Poland's border with Belarus, an automatically-generated text message pops up on your cell phone. It warns any refugees to turn around. 

"The Polish border is sealed. Belarussian authorities told you lies. Go back to Minsk!" reads the advisory, adding: "Don't take any pills from Belarusian soldiers."

On a small strip of land along the Polish-Belarusian border a battle is being waged, not with guns and ammunition, but with human lives.
