(BBC News) The authorities in Augsburg, southern Germany, plan to evacuate 54,000 people from the city centre on Christmas Day because of a World War Two bomb.
The 1.8-ton British bomb was found during construction work. Defusing it is expected to take most of the day.
It will be Germany's biggest post-war evacuation for an unexploded bomb, Spiegel news reports. In 2011, 45,000 residents of Koblenz were evacuated.
