NEW DELHI (AP) — A bus has fallen into a mountain gorge in northern India, killing 13 people and injuring dozens more.

Police officer Sandeep Negi says the bus went off a road at a turn and plunged into a deep gorge Monday night. The accident occurred while the bus was returning from the Himalayan foothills to the town of Saharanpur in Uttar Pradesh state after visiting the lake resort town of Renuka ji in Himachal Pradesh.

Negi says 13 of the 61 Indian tourists on board were killed, while another 43 were injured, including some in critical condition.

Rescuers used a crane to lift the vehicle from the gorge. Authorities were investigating the cause of the accident.

India has the world’s deadliest roads, with more than 110,000 people killed annually.
