Migrants 'trapped' in Belarus-Poland border crisis

A crisis is unfolding at the border of Poland and Belarus, where thousands of migrants are stranded in freezing temperatures, hoping to reach Europe. Belarus, under authoritarian President Alexander Lukashenko, is accused of deliberately creating this crisis by shepherding migrants from the Middle East to the Polish border as revenge for sanctions imposed on his regime. Poland, with the support of the European Union, has responded by fortifying its border in a massive show of force. Almost 20,000 police and soldiers have been deployed to the area, and there are claims that they have illegally pushed people back across the border into Belarus. Today, Guardian correspondent Lorenzo Tondo on the geopolitical standoff and the people trapped in the middle of what is increasingly looking like a humanitarian disaster.
