This is the terrifying moment two gas cylinders from a roadside tea stall exploded and injured six people. The metal tanks had been used to fire up the hot water and cook snacks on the stand in Mahbub Nagar, South India, but appeared to malfunction. CCTV captured the moment they burst into a huge fireball which knocked six people to the ground and smashed the windows of cars parked nearby. The window panes of homes opposite were also smashed. Miraculously, nobody was killed in the blast on January 25.
