Twenty-one passengers, more than half of them foreign tourists, were injured when their bus overturned in Pursat province’s Krakor district early on Friday morning, police said yesterday.

Krakor district’s traffic police chief Som Pilot said the passengers, including 13 foreign nationals from Norway, France, Canada, the Netherlands, Germany and Denmark, were treated at a provincial hospital before being released.

“The tourists told us that the wreck was likely caused by the driver, who lost concentration due to sleepiness,” he said.

According to investigators, the Angkor Express bus careened to the left and off national road 5.

When the bus driver braked in an attempt to swerve back onto the road, the bus toppled over.
