The London ambulance service said a number of resources have been sent to the scene in Seven Sisters Road. Kevin Bate, deputy director of operations, 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 Londons air ambulance has also been dispatched by car.
Images and video posted to Twitter showed police vehicles blocking the street and a cordon in place. More than a dozen emergency vehicles could be seen near the UKCG Help Centre at the junction of Seven Sisters Road and the A503 Tollington Road.
One resident told the Press Association he jumped out of the way as the van struck pedestrians. The man, who did not want to be named, said: The gentleman went straight down this road, people were just conversing, talking, just doing what were doing.
And he just came into all of us. There was a lot of people. We got told to move straight away. I was shocked, shocked, shocked. There were bodies around me. Thank God I just moved to the side, I just jumped. Everyone is hurt. Everyone is actually hurt.
Another witness Abdikadar Warfa told the Guardian he and and others caught hold of the van driver, who threw kicks and punches as he tried to escape.
Warfa said: He tried to run away he tried to escape. Some people were hitting him he was fighting to run away.
I heard the sound of the van crashing. One person was under the van,
some were run over.
My friend said he had to lift the van, I was busy with a man who tried to escape. My friend said he said some words, but I didnt hear it.
One witness, who asked not to be named by the Guardian, said: I was sitting in a cafe. My cousin was injured, hes in hospital now. Someone told me two people were stuck under the van. People tried to lift the van up. Police were quick to the scene.
One woman who lives opposite the scene told the BBC: From the window, I started hearing a lot of yelling and screeching, a lot of chaos outside. Everybody was shouting: A vans hit people, a vans hit people.

Prime Minister Theresa May has described the attack on worshippers near Finsbury Park mosque as a terrible incident, adding: All my thoughts are with those who have been injured, their loved ones and the emergency services on the scene.

in Westminster in March and and the second was a fortnight ago in London Bridge.
