Flights In and out of the London Airport has been cancelled after an unexploded bomb from World War II was discovered at George V Dock during work at London City Airport on Sunday morning.
Police set up a 214-metre exclusion zone at 10pm on Sunday to decrease risks to the public while the device was dealt with. The airport was closed and properties nearby evacuated.
Road cordons have also been put in place with drivers warned about disruption to their journeys if travelling through Newham.
A tweet from the airport said: “All passengers due to travel from London City on Monday are advised to contact their airline for further information. Passengers are advised not to travel to the airport until further notice.”
Specialist officers are working with the Royal Navy to remove the ordnance, the Metropolitan Police said.
A spokesman said on Sunday night: “At 10pm 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.
“There will also be disruption to inbound and outbound flights during the operation.
