Experts from the Ministry of Defence have detonated a bomb found on a building in southwest London, smashing residents' windows.
Police evacuated 1500 homes in the Kingston area after the bomb was found on Thursday morning (local time).
On Friday about 4pm (local time), the bomb was safely detonated, Sky News reports.
Residents' have since been able to return to their homes but it appears some houses sustained damage.
A Twitter post from a man shows shattered upstairs and downstairs windows on a house, while another wrote that she was "waiting to get my window boarded up".
European election polling booths near the scene also had to be closed, Sky News reports.
Once the Defence Force detonated the bomb, those nearby commented on the noise of the explosion.
"Wow that was loud...the Kingston bomb has just been detonated... my desk is a mile away," one said in a Twitter post."
"All the birds fell out of the trees, followed by loud cheers and celebrations heard afterward!" another wrote.
Police investigations are continuing.
