The ambulance service says the injuries are not thought to be serious – but a local school says it would have been “traumatic” for pupils.
Two children have been taken to hospital after a school bus had its roof ripped off during a crash with a car in Essex.
It happened around 8.15am on Clatterbury Lane in Clavering – a village between Bishop’s Stortford and Saffron Walden.
The ambulance service said three children were assessed at the scene and two of them taken to Addenbrooke’s hospital in Cambridge.
It said they are believed to only have minor injuries.
An air ambulance and fire crews were among the emergency vehicles sent to the scene.
Essex Fire and Rescue Service said the crash involved a bus and a car.
“The bus had also collided with a tree branch causing extensive damage to the roof,” it added.
“Nobody was trapped in either vehicle and firefighters worked alongside partners to make the scene safe by 9am.”
Pupils from two schools – Saffron Walden County High School and Joyce Frankland Academy – were on the bus.
The academy said that the crash involved the number 446 Stephenson’s school bus and that it would have been “traumatic” for pupils.
It said some students were having cuts and grazes looked at, but that no serious injuries had been reported.
A statement added: “Parents of the students involved are being contacted directly and the school has made arrangements to collect the students and offer a space inside the school for anyone who is in shock or upset by the events.”
Sky correspondent Rachael Venables said the road was still closed at Thursday lunchtime but that a tow truck had arrived to remove the bus.
