Eighty-seven people, including children, were hurt in a bus pile-up in Hong Kong.

The accident, which involved four passenger buses and a lorry, happened after noon on Friday near a tunnel in Tseung Kwan O Road in Lam Tim, a residential area in Kowloon.

Most injuries were minor.

A taxi carried out a “careless lane change” and the other vehicles could not stop in time, causing the smash, senior police inspector Lee Pok-kit said.

Numerous firefighters, paramedics and police officers were called to the scene.

Several people lay on stretchers and at least one passenger was seen being helped from a vehicle.

A window on the side of a bus was shattered.

Some of the injured, including elderly people, were treated by paramedics at the scene.

A group of primary school pupils was seen sitting on the road and some of them had hand injuries.

Lam Tin fire station commander Shen Chuen said his team helped 240 people leave the vehicles and the operation was challenging because there were so many children and elderly passengers.

A bus driver was also trapped, he said.

The injuries mainly included scratches on people’s hands, legs, heads and faces, according to Wong Po-lung, Lam Tin’s ambulance depot commander.
