One million Ukrainians have fled to Germany since Russia's invasion. On the outskirts of Berlin, almost 1,000 people sleep in giant heated tents on a former airport runway. The German capital is struggling to house Ukraine's refugees properly. As winter deepens and Russia continues attacking Ukraine's energy infrastructure, authorities are hastily preparing more emergency shelters in anticipation of up to 10,000 more Ukrainians. Germany initially extended a warm welcome, but there are now growing concerns about how best to accommodate such a large number of people. Around 100 Ukrainians arrive every day at the main refugee reception centre in the airport terminal. Workers in brightly coloured tabards lead them to departure halls filled with trestle tables offering food, medical aid and a bed for a ‘temporary’ stay. But many will stay in bunks in shared cubicles or tents for longer than a few days. Permanent accommodation is getting harder to find.
