Police and the Royal Navy will work through the night to guide an unexploded Second World War bomb down the River Thames.

London City Airport will remain closed for the rest of the day.

After guiding the 1.5 metre long bomb down using a flotation device, a controlled underwater explosion will take place tomorrow morning.

Chief executive of London City Airport Robert Sinclair said: "Any passengers due to fly today are urged not to come to the airport and to contact their airline for further information.

"I recognise this has caused inconvenience for our passengers, and in particular some of our local residents. The airport is co-operating fully with the Met Police, Royal Navy and London Borough of Newham to safely remove the device and resolve the situation as quickly as possible."

Woolwich Ferry services will also be affected because of the airports closure.

A number of roads in north Woolwich remain closed this evening after the bomb was discovered near the King George V DLR Station.

Bus routes 473 and 474 are being diverted.

Officer in charge of the diving unit, Jonny Campbell, said: ""There's a long night ahead for quite a few people, not least my Royal Navy bomb disposal divers, using our tried-and-tested techniques to remove the threat."

"We assess that we've got good control, that the bomb is in relatively good condition and so it's now that balance of yes, we want to take it away and remove it, but we want to make sure it's done properly."

Docklands Light Railway services between Pontoon Dock and Woolwich Arsenal were suspended earlier after the discovery.

London City Airport is the 14th busiest in the UK with 4,540,000 passengers in 2017, according to data from the Civil Aviation Authority.
