Heavy rains in western Maharashtra state triggered landslides and flooding, killing more than 100 people and causing widespread destruction.

Rescuers in India have combed through mud and debris in a frantic search for survivors as the death toll from heavy monsoon rains climbed to 115, with nearly 150,000 others evacuated.

Torrential downpours have lashed India’s western coast in recent days, leaving dozens missing near the financial capital Mumbai and causing the worst floods in decades in the resort state of Goa.

“Torrential rainfall in various parts of the state often coinciding with high tides and also discharge from dams led to various regions … getting inundated thereby resulting in floods across multiple districts,” the Maharashtra state said in a statement.

In hard-hit Raigad, south of Mumbai, where landslides buried dozens of houses, at least 47 people were killed and 53 others were feared trapped under layers of mud.

The downpour caused the Savitri river to burst its banks, leaving the town of Mahad completely inaccessible by road, and prompting terrified residents to climb onto rooftops and upper floors to escape swelling waters.

A combined rescue operation involving the army, navy, and air force were underway to evacuate those stranded by the flooding. Their operations, though, were hampered by high water levels and landslides blocking roads, including the main highway between Mumbai and Goa.
