The attack saw a man drive a van into a crowd of people leaving a mosque on Seven Sisters Road around 12:20am this morning.
One person died and ten others were injured as a result, and the man - who is reported to have shouted "kill me, I want to kill all Muslims" - has been arrested by the police.
The attack happened in the constituency of Highbury & Islington, which is represented by Jeremy Corbyn in Parliament.

Sadiq Khan, the Mayor of London and a Muslim himself, tweeted this in response to the incident:
Prime Minister Theresa May has yet to make a public statement - she is believed to be chairing a meeting of the Government's emergency Cobra committee.
