Up to 16,000 passengers were today hit as all flights at the London City Airport were cancelled for the day after a 500-kg World War II bomb was found nearby in river Thames, officials said.
The airport was shut at 22:00 GMT yesterday and the police said it was working with the Royal Navy to remove the bomb.
The airport will be shut all day and all flights are cancelled, affecting up to 16,000 passengers, a spokeswoman said.
"I urge any passengers due to fly today not to come to the airport and to contact their airline for further information," he said in a statement.
"I recognise this is causing inconvenience for our passengers, and in particular some of our local residents. 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," he added.
Families in the area were evacuated with the exclusion zone set to be widened when specialists begin removing the device.
"The timing of removal is dependant on the tides, however, at this stage we estimate that the removal of the device from location will be completed by tomorrow morning," a statement issued by the Met Police said.
