Prime Minister Theresa May says the terror attack near a north London mosque is "every bit as sickening" as recent ones to hit the UK, according to BBC.
She was speaking after a man died and 10 people were injured when a man drove a van into worshippers near a north London mosque.
Eight people were taken to hospital after the attack outside the Muslim Welfare House.
A 48-year-old man has been arrested on suspicion of attempted murder.
A group of people were helping a man who had collapsed when they were hit by the van just after midnight. The man has died, but it is unclear whether this was as a result of the attack.
Police said all the victims of the attack, which was in the area of Finsbury Park Mosque, were Muslim.
