BEIJING (AP) — A bus flipped over and burst into flames after it was rear-ended by a cargo truck in south China on Monday, killing at least 26 people and injuring 31, state media said.

The official Xinhua News Agency said in a brief online report that the accident occurred at 3:50 a.m. Monday on a highway in Hubei province.

It said people aboard both vehicles were hurt or killed and the number of the injured was likely to rise.

Serious traffic accidents are common in China due to lax driving habits, overloaded vehicles and bad road conditions.
