Thousands of residents in Frankfurt, Germany have evacuated their homes ahead of the scheduled defusal of a major World War II bomb.
The bombs were found last week at a building site, in what is the country's biggest evacuation since the war.
About 60,000 people had to leave their homes after being warned that an uncontrolled explosion could flatten a city block.
Police set up cordons around the evacuation area, which covered a radius of 1.5 kilometers, as residents hauling suitcases or riding bicycles left the zone.
The fire service said the evacuation of two hospitals, including premature babies and patients in intensive care, had been completed and they were now helping about 500 elderly people leave residences and care homes.
More than 2,000 tons of live bombs and munitions are found each year in Germany. In July, a kindergarten was evacuated after teachers discovered an unexploded World War Two bomb on a shelf among some toys.
In Frankfurt, bomb disposal experts will use a special system to try and unscrew the fuses attached to the HC 4,000 bomb from a safe distance. If that fails, a water jet will be used to cut the fuses away from the bomb.
