A 100-year-old man has driven his car onto a pavement in Los Angeles, hitting 11 people including nine children.
The driver, named by police as Preston Carter, backed his powder blue Cadillac into a group of parents and children buying snacks from a street stall.
The accident happened outside a primary school in south Los Angeles as children were on their way home, according to US authorities.
Onlookers banged on the car windows and screamed for the pensioner to stop as he reversed slowly but by the time he did, some children were trapped under the vehicle.
Children's rucksacks, shoes, sweets and loose change were strewn around the pavement and road behind a grocery shop after the drama.
LA fire captain Jaime Moore said four of the children had been in a critical condition when firefighters arrived but that they were stabilised at the scene.
They are now in a serious condition in hospital. Two adults were also injured in the accident.
