MANSEHRA, Pakistan — A bus carrying Chinese and Pakistani construction workers on a slippery mountainous road in northwest Pakistan fell into a ravine Wednesday, killing at least 13 people, including nine Chinese nationals, officials said.
At least 36 people were also injured in the apparent accident in the Kohistan district of Khyber Pakhtunkhwa province, said Arif Javed, a deputy district commissioner.
The incident happened on a wet road following an overnight rain but Pakistani officials were still investigating and the Chinese Embassy said in a statement the bus was attacked.
Chinese engineers and construction workers are helping Pakistan build a dam in Kohistan. Javed said the Pakistani and Chinese construction workers were on their way to the project site when the accident happened.
Asim Abbasi, an assistant commissioner in Kohistan, said authorities believe the incident was an accident but were investigating whether there was some type of explosion in the bus. He said a gas cylinder may have exploded
