A fire broke out at a multi-storey commercial building in Bengaluru's posh Koramangala locality today. Visuals showed a huge explosion on the top floor of the building amid the fire, reportedly due to cooking gas cylinders going off. In more visuals, a man was seen clinging on to the corner of the terrace of the four-storey building as the fire continued to spread. He looked at the fire towards his right, and then on the ground below. Then he suddenly jumped. He and another person suffered critical injuries, and they have been admitted to a private hospital, news agency PTI reported.
