At least 36 people have died and 13 are injured after a passenger coach crashed into the wall of a tunnel in China.
The injured have been taken to hospital and rescue efforts are ongoing.
The accident occurred in Shaanxi province in the northwest of the country.
It was not immediately clear if the coach was the only vehicle involved.
According to state broadcaster China Central Television an investigation into the accident has been ordered.
Highway accidents are common in China because of high speeds, aggressive driving and a failure to leave adequate braking distance.
The World Health Organization estimates that traffic accidents kill around 260,000 people in mainland China each year - a rate of 18.8 in every 100,000 people.
