Rescue operations at a flooded coal mine in Assam's Dima Hasao district continued for the seventh day on Sunday to locate trapped labourers inside the quarry. The bodies of four labourers have been recovered so far, with the dewatering process expected to reach its final stage soon. The mine was abandoned 12 years ago and was under the Assam Mineral Development Corporation until three years ago. The leader of the workers has been arrested and the police are conducting investigations into the case.
