People were evacuated on Thursday after a massive unexploded bomb was found buried on a building site in north-west London.
Schools, businesses and homes were evacuated and roads closed as experts from the Army’s Royal Engineers worked from early Friday to make the German bomb safe.
London was heavily bombed in the war, especially during the Blitz of 1940 and 1941 which concentrated on civilian and industrial targets. Unexploded devices are still occasionally uncovered.
The bomb was found on Thursday by construction workers clearing the site in preparation for putting up an apartment block.
Some residents living near the site spent Thursday night in a local church while the engineers worked.
