London City Airport was closed on Sunday after construction workers discovered a World War II bomb in the nearby Thames River.
"Following the discovery of a World War II ordnance in King George V Dock as part of planned development works, a 214m exclusion zone has been implemented," the airport said in a statement. "As a result, London City Airport is currently closed."
Metropolitan police were called after the bomb was revealed. The Royal Navy was also deployed to the scene and confirmed the nature of the bomb, the police reported.
"The airport is cooperating fully with the Met Police, Royal Navy and London Borough of Newham," the airport's statement added.
