London City Airport says all flights in and out have been canceled for Monday after an unexploded World War II-era bomb was found nearby in the River Thames at King George V Dock. Police said the ordnance was found during work at the airport on Sunday and they set up a 200-metre exclusion zone, adding that all properties within the zone had been evacuated and a number of roads were cordoned off. Londons Metropolitan Police and Royal Navy are cooperating to remove the bomb. Robert Sinclair, CEO of London City Airport, the city’s fifth biggest and the most central, said: “The airport is cooperating fully with the Met Police and Royal Navy and working hard to safely remove the device and resolve the situation as quickly as possible,” Reuters reported. British Airways said it was trying to minimize disruption for passengers after the airport’s closure. “We are rebooking customers due to travel today onto alternative flights or offering refunds for those who no longer wish to travel,” the airline said in a statement. London was heavily bombed during the Nazi German air attacks of September 1940 to May 1941, according to AFP. London City Airport opened in 1987 in the disused docklands.
