As many as 25 passengers were injured when a bus overturned after it was hit by boulders in ward 29 of Bharatpur Metropolitan City along the Narayanghat-Mugling road on Friday afternoon.

Among the hurt, two have sustained serious injuries, police said.

The bus turned turtle as the driver lost control of the wheels after rocks hit the vehicle.

Deputy Superintendent of Police Bhesh Raj Rijal, spokesperson for the Chitwan District Police Office, said the rocks fell onto the bus en route to Pokhara from Gaur, Rautahat, at around 1:45 pm.

The injured passengers are receiving treatment at hospitals in Chitwan.
