BERLIN (AP) - German authorities have shut down Berlin's main international airport after construction workers discovered a World War II bomb there.
A police spokesman told the Associated Press on Wednesday the bomb's weight is estimated at a quarter ton.
Police said no planes are allowed to land or take off from Tegel Airport until experts manage to defuse the bomb. Police are blocking all access roads.
Local media reported the airport would remain closed until the evening, forcing the cancellation or diversion of dozens of flights.
Tegel handled 14.2 million passengers last year, according to the airport's Web site. The capital's second hub, Schoenefeld, handled 6.6 million passengers last year.
