Chinese state media say 10 people have been killed in an accident involving a minibus, on the first day the peak travel season started for the Chinese New Year.

The official Xinhua News Agency said Wednesday that the minibus was carrying 13 people and that 10 were killed in the southern Chinese city of Meizhou.

It says the minibus was believed to have been overloaded but gave no further details.

Poor road conditions, bad driving habits, and overloading — a problem exacerbated during holidays — are major causes for road accidents in China.

China's transportation system is expected to accommodate 2.8 billion trips this year during the 40-day New Year travel period, when people travel for family unions.
