An unexploded World War II bomb has been unearthed near Berlin's main train station, risking possible disruptions to rail and road traffic, authorities said Wednesday.
.
"The bomb was found yesterday afternoon on property belonging to the rail company," a police spokesman told AFP, adding that the 100- kilogramme (220-pound) explosive was dropped by the Allies during the Second World War.
.
The site lies about 1.5 kilometres (0.9 miles) north of the main train station and the spokesman said police were still determining how to re-route road traffic around the area.
.
A spokesman for the rail operator, Deutsche Bahn, said it was deliberating whether to re-direct trains while authorities defuse the bomb or destroy it in a controlled explosion.
.
More than six decades after the war, authorities believe there are still some 3,000 bombs buried beneath Berlin alone, and unexploded devices are regularly discovered in construction work.
.
In June 2010, a 500-kilo Allied bomb, thought to be British, exploded and killed three German sappers, and seriously injured two others in the central city of Goettingen as they prepared to defuse it.
