One person was killed and 10 others injured on Monday when a van collided with pedestrians near a North London mosque in an incident which is being investigated by counter terrorism officers, police said.

"One man was pronounced dead at the scene," the Metropolitan police said in a statement.

Police said eight people had been taken to three separate hospitals and two people were treated at the scene for minor injuries.

A 48-year old van driver, who was detained by members of public at the scene and then arrested by police, has been taken to hospital and will be subject to a mental health assessment.
