Rescuers have ended a 44-day search operation after they found the bodies of five men who were trapped inside a flooded coal mine in India's north-eastern state of Assam.

DNA tests will be conducted to identify the men as the bodies are in a decomposed state, a state official told the BBC.

On 6 January, nine miners were trapped after water flooded the so-called "rat-hole" mine, which is a narrow hole dug manually to extract coal.

Four bodies were recovered within the first week, and search operations had continued until Wednesday, when the remaining bodies were found.

"The process to identify the remains has been initiated," Assam Chief Minister Himanta Biswa Sarma said on the social media platform X.

The families of the miners have also been called to identify the bodies. They will be given compensation by the state government, said Riki Phukan, an official from Assam's District Disaster Management Authority.

The search operations - at the Umrangso coal mine in Assam's Dima Hasao district - were jointly conducted by special disaster forces alongside the Indian Army, the Indian Navy, the state police and the district disaster authority.

Divers and helicopters were also deployed but the remote, hilly terrain of the mine had posed severe challenges.

Earlier, one of the men rescued from the mine had shared with the BBC a harrowing account of the moments after the tunnel was suddenly engulfed by water.

Ravi Rai, a worker from Nepal, said that he was working inside the mine when water entered the pit.

"We were holding on to a rope in 50-60ft (15-18m) deep water for at least 50 minutes before being pulled out," he said.

Despite a ban on "rat-hole" mining in India since 2014, small illegal mines continue to be operational in Assam and other north-eastern states.

Six workers were killed in January 2024 after a fire broke out in a rat-hole coal mine in Nagaland state.

In 2018, at least 15 men were trapped in an illegal mine in Meghalaya after water from a nearby river flooded it.

After the recent accident, police in Assam have said they are investigating illegal mining activities in the state.
