British Prime Minister Theresa May says a terror attack near a London mosque is "every bit as sickening" as others in recent weeks.
A man drove a van into worshippers close to Muslim Welfare House in Finsbury Park as they were gathered to help an elderly man who had collapsed.
He later died, but it is not clear if this was a result of the attack.
Nine other people were taken to hospital.
A 47‑year‑old man was held on suspicion of the commission, preparation or instigation of terrorism including murder and attempted murder.
It is the fourth terror attack in the UK in three months, after incidents in Westminster, Manchester and on London Bridge.
Police said all the victims of the attack shortly after midday yesterday were Muslim and many were believed to have just left evening prayers after breaking the Ramadan fast.
