Chinese officials say a bus overturned on a highway and then was hit by an oncoming truck in eastern China, killing at least 10 people.

The government of Wuhu city in Anhui province said a number of other people were injured in the accident Friday and that its cause is being investigated.

State broadcaster China Central Television said the bus overturned into the opposite lane of the highway and was hit by the truck.

The number of people in the two vehicles was not immediately known.

Road accidents in China are often caused by poor driving habits, inadequate maintenance, overloading and dangerous mountain roads. The number of motorists has been rapidly increasing.
