London City Airport has been temporarily closed after an unexploded World War Two bomb was found nearby in the River Thames at George V Dock.
All Monday flights in and out of the airport have been cancelled, and authorities have secured the area. As many as 261 flights, carrying upwards of 16,000 passengers are believed to be affected.
Police have also closed the London DLR between Pontoon Dock and Woolwich Arsenal as a precaution and a replacement bus service is available.
The bomb was discovered by workmen while performing planned work at the busy east London airport, and the Royal Navy and bomb disposal teams are working to safely remove the explosive device.
In a statement, the Metropolitan police said: “The unexploded ordnance was discovered as part of pre-planned work at London City Airport and reported to the police at 05:06hrs on Sunday, 11 February. Specialist officers and the Royal Navy have attended and confirmed the nature of the device.
“At around 22:00hrs on Sunday, 11 February an operational decision was made with the Royal Navy to implement a 214-metre exclusion zone to ensure that the ordnance can be safely dealt with whilst limiting any risk to the public.”
London City Airport CEO, Robert Sinclair, added: “The airport remains closed this morning following the discovery of a World War Two ordnance in King George V Dock on Sunday. All flights in and out of London City on Monday are cancelled and an exclusion zone is in place in the immediate area.
“All flights in and out of London City on Monday are cancelled and an exclusion zone is in place in the immediate area. I urge any passengers due to fly today not to come to the airport and to contact their airline for further information.
