The discovery of a 250 kg World War II bomb has forced evacuation of about 5,000 people in a German city.
The bomb was found yesterday in Cologne city during construction work near a 45-storey building housing about 2,000 people.
The tricky construction of the fuse prompted bomb disposal experts to opt for a controlled detonation of the bomb and residents within a radius of 300 meters of the detonation site were evacuated, local media reported.
Earlier this month, a construction worker manning a digger was killed when he accidentally struck a World War II-era bomb during excavation work in Euskirchen in Germany's western state of North Rhine-Westphalia.
Two people were critically injured in the blast and 11 others suffered minor injuries, local media reported.
Nearly 69 years after the end of World War II, thousands of unexploded bombs are still believed buried in Germany.
