At least 35 people have reportedly been killed as a bus slipped off the road into a deep gorge in Raigad district of Maharashtra.
According to initial reports, the staff members of Dapoli Agriculture University, Raigad were going for a picnic when the accident took place.
NDRF teams from Pune have rushed to the accident site near the popular tourist destinations of Mahabaleshwar-Panchgani.
Rescue efforts were severely hampered by heavy rains lashing the Western Ghats, besides poor connectivity in the remote hills in the area.
The accident came to notice after one of the injured passengers managed to climb up and alerted the authorities.
