At least 36 people were killed when a bus crashed into the wall of an expressway tunnel in China's northwest, the official Xinhua news agency says.
The bus hit the wall of a tunnel along the Xi'an-Hanzhong expressway in China's Shaanxi Province shortly before midnight on Thursday (local time), Xinhua reported, citing provincial authorities.
Thirteen people were injured and were rushed to hospital, Xinhua said. Rescue work was still underway.
The bus was travelling from the southwestern city of Chengdu to Luoyang city in China's central Henan province.
China does not release statistics on the total number of accidents each year, but the World Health Organization estimated in 2013 that around 250,000 people were killed on Chinese roads that year.
Beijing has vowed to clamp down on dangerous driving, but the rapid growth in car ownership and relatively lax checks on driving ability have made it difficult to curb the number of accidents, especially on rural roads.
