German police have defused a World War II bomb in central Berlin, after some 10,000 people were evacuated.
All buildings within an 800-metre (2,625 ft) radius will be evacuated from 9 a.m. local time (0700 GMT) on Friday, police said on Twitter.
Bomb disposal experts defused a World War II bomb in Berlin on Friday after evacuating an area in the heart of Berlin including the central train station, a hospital and the Economy Ministry.
Ritters said the bombs were quite stable while they were not being moved, but once they begin to move it can become unsafe, which is why authorities were not taking any risks.
It was found last Wednesday during construction work in Heidestrasse.
Police said they had no idea as yet how long the operation to defuse the bomb would take and would depend on the condition of the missile.
Even 73 years after the end of the war, such discoveries remain common in major German cities.
Previous year some 60,000 people were evacuated from their homes in Frankfurt after a massive bomb dropped by Britain's Royal Air Force was unearthed.
In one of the more sensational finds, a 250-kilogram (550-pound) British bomb was found in 2002 beneath the lower ring of seats during renovation work at Berlin's Olympic Stadium, where tens of thousands of fans regularly watch the city's Hertha BSC soccer club play its home games.
Flights to and from Tegel airport - about 7km away - were not affected by the evacuation.
