London City Airport closed after unexploded WWII bomb is found

Some 284 flights were cancelled at London City Airport on Monday after an unexploded WWII bomb was discovered in the nearby River Thames.

LONDON — One of London's airports has been closed after an unexploded World War II bomb was discovered nearby.

The ordnance was found in the River Thames during pre-planned work at London City Airport on Sunday, according to the Metropolitan Police.

The airport was shut at 10 p.m. local time (5 p.m. ET) and a 700-foot exclusion zone was set up to allow Royal Navy experts to safely remove the bomb. Local residents were also asked to leave their homes overnight.

A total of 284 flights were canceled Monday, affecting around 9,000 people, a spokesman for the airport told NBC News.

London was heavily bombarded during the Second World War and unexploded ordnance is regularly discovered, particularly during construction work.

London City Airport's runway was purpose-built on a marina adjacent to the Thames in 1987. A $477 million plan to expand the airport was approved in 2016.
