Berlin - The German city of Munich on Wednesday was assessing the damage from a controlled explosion of a World War II bomb that had rested underground in the city centre for seven decades.
The blast on late Tuesday set off fires that gutted a shop, damaged the roofs of nearby apartments, and smashed windows.
Disposal crews can usually defuse unexploded bombs by unscrewing their detonators. But experts concluded the 250-kilogram bomb, which was discovered during excavation for a new building, could not be safely dismantled.
Meanwhile, another buried World War II bomb prompted the closure of a section of Schiphol airport in Amsterdam on Wednesday, Dutch media reported.
A bomb squad was called in after the device was found during construction at the airport's C-Pier, De Telegraaf newspaper said. The terminal is used for flights within Europe's Schengen zone.
Massive numbers of bombs were dropped on European cities during the war. Searching for those that are buried and unexploded remains a full-time job for disposal squads.
On Tuesday, the headquarters of Poland's National Bank and Polish television station TVP in Warsaw had to be cleared after workers building a metro line uncovered a 1.5-ton bomb from World War II.
Some 3,000 people were evacuated while disposal crews defused it.
