Six people including three children have been taken to hospital after a car crashed into a crowd of Muslims leaving Eid prayers outside a sports centre in Newcastle.
Police said the collision outside the Westgate Sports Centre around 9.14am is not believed to be terror-related.
An eight-year-old boy is said to have been critically injured, the BBC reports.
A 42-year-old woman has been arrested and is currently in police custody.
Footage from the scene showed members of the public running towards the scene of the crash amid the sound of shouts and screams.
Hundreds of people were at the sports centre to celebrate Eid al-Fitr, the end of the Muslim holy month of Ramadan.
The six injured people were taken to the Royal Victoria Infirmary.
A North East Ambulance Service spokesman said: "We received our first 999 call at 9.15 this morning to report a car that had mounted the kerb.
"We have taken six people to hospital, they have gone to the Royal Victoria Infirmary in Newcastle, three children and three adults."
Assistant Police Constable Darren Best, from Northumbria Police, said: "A 42-year-old female had been celebrating Eid with her family. She then got into her car and has collided with six people in the crowd.
"We have no information to suggest this is a terror-related incident. However, this is a serious collision, with multiple casualties and extensive inquiries are ongoing to establish the circumstances around this tragic incident.
"The six people injured, three of which are children, have been taken to hospital.
"As it currently stands, two of the children are now in paediatric intensive care and one adult is in the trauma high dependency unit. The remaining injured are believed to have serious but non-life threatening injuries."
He said extra officers would be on patrol to answer any questions or concerns the public may have.
He said it "appears to be a road traffic collision that we are dealing with."
