The German city of Cologne is evacuating some 20,500 people from a large area in the city centre so experts can defuse three unexploded bombs from World War Two.
The American bombs were discovered on Monday in a shipyard in the Deutz neighbourhood.
Unexploded bombs can still pose a danger and the city has sealed off the zone within a 1,000m (3280ft) radius, in what it described as "the largest operation since the end of WW2".
