The destruction of the area was all but complete. Bewildered local residents have held candlelight vigils and prayed for peace.
Scores of people were also injured but most have been released from hospital, according to the Iraqi health ministry.
The ministry said those critically injured had been sent abroad, without giving further details.
The bombing in a mostly Shia Muslim area just after midnight came a week after Iraqi forces had recaptured the city of Falluja from IS.
