MUMBAI : Two people, including a child, were burnt to death and 11 others, among them three women, suffered injuries in a fire that caused several gas cylinders to explode in a northwest Mumbai slum on Monday, officials said. The fire erupted at around 12.30 p.m. in the sprawling and densely populated Damunagar slum in Kandivali East. Within minutes, several gas cylinders in a nearby warehouse also caught fire and started exploding. Witnesses said there were at least half a dozen deafening explosions and a thick smoke, billowing from the flames, was visible several kilometres away. Around 2,000 hutments were gutted and the impact of the exploding cylinders led to a power failure in the entire locality that comprises posh skyscrapers of Thakur village. Over 15 fire tenders, 10 water tankers and five ambulances were pressed into service in relief operations and the blaze was brought under control after nearly four hours. The cause of the massive blaze that engulfed an area spread over 50,000 square metres is being investigated.
