Prakash Mehta, the Guardian Minister of Raigad district, yesterday said as many as two buses and five-six private vehicles were still missing after a bridge over the Savitri River collapsed. Mehta confirmed that two buses and at least six private vehicles had fallen into the river, adding the water flow was too strong to undertake a rescue effort.

The buses were travelling between Jaigad-Mumbai and another Rajapur-Borivali, respectively. The Maharashtra government, National Disaster Response Force, Navy and Coast Guard launched a massive air and sea operation. Meanwhile, heavy rain is causing hurdles in the rescue operation.

The disaster struck after heavy rains flooded the Savitri river, which originates in Mahabaleshwar and flows through Ratnagiri-Raigad districts. The sheer force of the flood waters built up huge pressure on the seven-decade-old bridge near Mahad around midnight and it collapsed, with around a dozen piers totally washed out by the gushing waters.

Incessant rains continued to hamper rescue operations in the region. Rains also continued to lash the entire coastal Konkan region as well as northern and western Maharashtra. The tragedy found its echo in Parliament and the Maharashtra assembly where several opposition leaders attacked the government for not shutting down the old bridge though it had exceeded its lifespan.
