The bomber had rammed his explosives-packed car into a checkpoint in Baghdad's northern neighbourhood of Kazimiyah where people lined up in cars for security checks en route to a revered Shiite shrine during the Islamic holy month of Ramadan.
Police officials said today that along with 31 killed, the explosion also left at least 58 people wounded. Initial reports had 21 killed. The officials spoke on condition of anonymity as they are not authorised to talk to media.
