The death toll from a boiler explosion at a Vedanta power plant in Sakti district, Chhattisgarh (a central Indian state), has climbed to 21 after another injured worker died on the night of 16 April. The blast, which occurred on 14 April at the facility in the Singhi Tarai area, also left 15 people injured. India's opposition Congress party has called for those responsible to face charges of culpable homicide not amounting to murder, pressing for accountability over the industrial disaster.
