A van has collided with worshippers leaving a mosque in north London, according to the Muslim Council of Britain.
The Metropolitan Police say they are dealing with a “major incident” as a result of the collision in Seven Sisters Road, Finsbury Park.
A Sky News producer at the scene says the incident happened as worshippers were leaving the Finsbury Park Mosque at midnight Ramadan prayers.
The council said on Twitter: “We have been informed that a van has run over worshippers as they left #FinsburyPark Mosque. Our prayers are with the victims.”
It added later that the collision occurred outside the Muslim Welfare House, which is nearby the mosque.
This year Ramadan began on 26 May and ends on Saturday 24 June.
Sky Mobile News Reporter Connor Sephton says that there is a wide cordon in place.
Witnesses have told him the “white” driver headed into the crowd “deliberately” and he was targeting the mosque.
He said the witnesses told him there were “definitely five” people on the floor after the collision.
Video images of the scene seen by Sky show a number of people on the ground with what appear to be a variety of injuries, some of whom look like they are seriously hurt.
The incident is described as being near to Finsbury Park station and the mosque, with pictures on social media suggesting it occurred at the entrance to Whadcoat Street.
London Ambulance Service say they have sent a “number of resources” to the scene.
Dozens of police, fire and ambulance service vehicles have been sent to the area, armed officers are on the scene and a helicopter is overhead.
The Met Police said in a statement: “Police were called just after 0020hrs 18 June to reports of a vehicle in collision with pedestrians
“Officers are on scene with other emergency services. There are a number of casualties being worked on at the scene.
“There has been one person arrested. Enquiries continue.”
London Ambulance Service Deputy Director of Operations, Kevin Bate said: “We were called at 12.15am to reports of a road traffic collision at Seven Sisters Road.
“We have sent a number of ambulance crews, advance paramedics and specialist responses teams to the scene. An advance trauma team from London’s Air Ambulance has also been dispatched by car.
“We are working closely with other members of the emergency services at the scene.
“Our priority is to assess the level and nature of injuries and ensure those in the most need are treated first and taken to hospital.”
Witness Cynthia Vanzella told Sky News she was trying to sleep when she heard a lot of noise outside.
She said: “I saw many people shouting, taking over half of Seven Sisters Road, I thought that something bad has happened.
“I could see at least two people on the floor, not moving. They were doing cardiac massage. It was difficult to watch.”
“There were people sitting on the floor with their head in their hands.
“In a matter of seconds a police car was here. They were very fast.”
Transport for London says Seven Sisters Road has been closed northbound between Hornsey Road and Rock Street.
