From Paul Armstrong's report for CNN, updated today at 7:32 PM EDT:
ISIS claimed responsibility for the attack on the predominantly Shiite neighborhood of Kadhimiya, which also injured more than 35 others, Iraqi security officials said.
The claim by ISIS was released by the terror group's media wing Amaq and on pro-ISIS social media accounts circulated by its supporters.
Sunday's attack came just weeks after the deadliest terror attack in war-weary Baghdad in years
, when a suicide truck bomb plowed into a busy shopping district killing almost 300 people.
ISIS losing territory but remains deadly
Analysts say this demonstration of the terror group's capacity to strike at the heart of the capital may force a delay of the long-awaited government push to retake the northern city of Mosul, the largest city under ISIS control.
The Sunni terror group, which has carved out a self-declared caliphate in parts of Iraq and Syria, has been losing territory, most recently in the Iraqi city of Falluja.
