The welcome to the so-called "last dictatorship in Europe" isn't warm. At the border, in a room resembling a Cold War set, a camera records my interrogation by a Belarusian soldier.

Around 3,000 migrants, most of them refugees from the Middle East, are trapped on the border between Belarus, which has accompanied them there, and Poland, which has barricaded their passage with riot police and tear gas. The families are enduring sub-zero temperatures and humanitarian actors are not allowed access. This is the latest crisis scenario in the EU.
