CCTV footage of the bomb blast triggered by a slow-moving car near the Red Fort in the Capital surfaced on Wednesday, as the National Investigation Agency (NIA) began its probe into the terror attack that has claimed nine lives so far. A 15-second clip of the incident captured on CCTV shows a congested area near the Red Fort metro station, as dozens of vehicles moved slowly. A huge ball of fire is then seen, as the i20 car - now believed to be the source of the explosion - rips through the area. The blast took place at 6.50pm on Monday, gutting several vehicles, the footage provided by the CCTV control room said.
