Thirty-two cars - including a Maruti Suzuka Brezza, Maruti Swift Dzire, and a Ford EcoSport - were being prepped to carry explosive materials and/or deliver bombs, sources close to the Delhi Red Fort blast investigation told NDTV Thursday. The cars - including the Hyundai i20 that exploded Monday evening - were meant to be part of a serial 'revenge' attack targeting multiple locations, including six in Delhi on December 6 - when the 16th century Babri Masjid in Ayodhya was torn down by a mob.
