Three French teenagers on a school visit to London were among those injured on Westminster Bridge.
Le Telegramme reported the students, aged between 15 and 16, were wounded in the attack with one ending up on the roof of the car.
The pupils from a school in Concarneau, Brittany, had arrived in London on Sunday evening.
Eyewitness Rick Longley told the Press Association he saw a man stab a policeman.
Fighting back tears he said: "We were just walking up to the station and there was a loud bang and a guy, someone, crashed a car and took some pedestrians out.
"They were just laying there and then the whole crowd just surged around the corner by the gates just opposite Big Ben.
"A guy came past my right shoulder with a big knife and just started plunging it into the policeman.
"I have never seen anything like that. I just can't believe what I just saw."

Witness Richard Tice said he "counted between eight and 10 prostrate figures on the ground" after he came out of Westminster underground station and moved on to Westminster Bridge.
He told Sky News: "My understanding from someone who was standing next to me was that a car had driven along the whole pavement knocking people over and that is why there were many injuries. The people lying on the ground were starting to be attended to by a paramedic."
Staff inside Parliament said the building was being evacuated floor by floor.
Police have been telling MPs and members of the public to clear the area immediatley.
Scotland Yard said in a statement: "Police are asking people to avoid the following areas: Parliament Square; Whitehall; Westminster Bridge; Lambeth Bridge; Victoria Street up to the junction with Broadway and the Victoria Embankment up to Embankment tube.
"This is to allow the emergency services to deal with the ongoing incident. Officers - including firearms officers - remain on the scene and we are treating this as a terrorist incident until we know otherwise."
Medical staff are treating two people, the BBC is reporting. There was a wave of people running down the street.
Alan Parry, of Sky Sports News, was at Westminster for a meeting when he heard "an almighty crash" when he was just outside the underground station .
He could see what he thought was a 4x4 vehicle on the other side of the road which had crashed into some railings.
He told Sky News: "There was smoke coming this vehicle. I walked on a few paces further and saw what I assumed to be either a pedestrian or a cyclist who had clearly been hit and wasn't moving, although he did then gently move.
"The guy who I assumed was the driver of this 4x4 got out of the car and suddenly sprinted away from the scene - that was followed by four of what sounded much like gunshots.
"All of a sudden all hell was let loose. Police descended everywhere and the whole area was locked down."
Sky News said that there was a sighting of what was thought ot be the Prime Minister's car being driven off. Theresa May is said to be safe.
A line of red buses and several ambulances could be seen on Westminster Bridge.
Alex Wafer, 47, who was cycling nearby and saw the aftermath, said: "At the end of the embankment it appears as though there is an ambulance.
"It looks as if they are treating somebody.
"And just below, it looks like there may be another paramedic treating someone else."
