The bus was on its way to Beawar from Delhi via Jaipur when the driver lost control over a turn and rammed the vehicle into a tree, following which it fell into a 15 feet deep gorge, they said.
The injured were rushed to nearby hospitals in Shahpura and Viratnagar, police said.
Due to traffic jam at the Delhi-Jaipur National Highway, the buses were being diverted through
Shahpura-Alwar-Viratnagar, they said, adding that the driver did not recognise the road diversion which led to the accident.
