At least 20 people are feared dead in Himachal Pradesh's Rampur after a private bus rolled down a gorge in the hill state on Thursday morning.
The bus was carrying around 40 passengers and met with the accident around 9:15 am.
The bus was on its way from Reckong Peo in Kinnaur to Solan and met the accident on National Highway 5 near Rampur, around 120 km from the state capital Shimla.
