Twelve people were killed and 32 others injured after a horse dashed onto a road in Inner Mongolia, causing a truck driver to swerve into a bus, news reports said Sunday.
Police are investigating the accident, which occurred in Inner Mongolia's Yakeshi City late Saturday, China's official Xinhua news agency reported.
Four people with serious injuries died on Sunday, bringing the death toll to 12. Another four people with serious injuries underwent surgery and are expected to recover, Xinhua said.
Fatal road accidents are common on China's highways and in the countryside, according to the government. In 2014, 21 per cent of crashes happened on the highway and 27 per cent of the accidents involved trucks.
The number of vehicles on the road in China has increased by 15 million cars each year for the past decade. Experts say unskilled drivers could be a factor in the high number of traffic accidents.
