While Photo Bai (45), Lila Bai (15) from Madhya Pradesh and Moti Pal (5) from West Bengal are recuperating in Chander Hospital of the township, Hashim Ali from MP was discharged after first aid. The doctors attending on all the three injured said that right leg of Photo Bai and Hashin Ali got fractured, while Navthipal received internal head injuries. ``All of them are out of danger and will be discharged by the week-end,'' they added. The labourers who were eyewitnesses of the incident told ENS that they heard an explosion and saw the walls of the tank falling down. They reached the venue, but it was too late since Ishwari Devi was no more, said one of them in a choked voice.
