At least 15 people died and dozens of others wounded on Saturday when a parked car bomb detonated in Sadr City district, a Shiite-majority area in northern Baghdad, where people gathered to buy and sell vehicles, said Iraqi police.
ISIS, which frequently targets Shiites, has claimed responsibility for the attack.
On Thursday, one of the worst single-day attacks happened in the same district when a massive truck bomb detonated in a Sadr City market, killing at least 76 people and wounded 200 others.
More than 3 million Iraqis have been displaced across all of Iraq’s 18 governorates due to conflicts in the country from January 2014 through June 2015, International Organisation for Migration (IOM) said in June.
Iraq has been facing a security vacuum since June 2014 after ISIS stormed the northern province of Mosul and extended its territories to the northern and eastern regions of Iraq.
