At least 37 passengers were killed when a bus plunged into a canal in the central Indian state of Madhya Pradesh, police told AFP as recovery efforts continued.
The accident happened early on Tuesday morning (local time) when the bus, which was carrying more than 50 passengers, veered off the road and into the water near the village of Satna.
It was unclear what caused the bus to swerve, but India's vast network of roads is poorly maintained and notoriously dangerous.
According to media reports, seven people, including the driver, managed to swim to safety.
"We have so far found 37 bodies and they have been sent for autopsy. Search and rescue operations are underway," District Police Superintendent Dharamveer Singh said.
The state government has ordered an inquiry into the accident.
An initial investigation suggested the driver lost control of the bus, reports said, before the bus hit a bridge and crashed into the water.
Local officials stopped the release of water into the canal, which sped up the rescue operations and allowed two cranes to pull the bus out, reports said.
Prime Minister Narendra Modi's office tweeted that the families of those killed would receive 200,000 rupees (A$3,530) in compensation.
"The entire state is standing with those affected," Madhya Pradesh chief minister Shivraj Singh Chouhan said in a video message.
High-speed vehicles jostling with motorbikes, pedestrians and cyclists combine with poor infrastructure and poorly maintained vehicles to make India's roads treacherous.
