The blast in Muqdadiyah also wounded at least 40 people, security officials said.

There was no immediate claim of responsibility for the attack, but suicide bombings are a tactic almost exclusively employed in Iraq by ISIL terrorist group.

The Muqdadiyah attack came a day after bombings in northern Baghdad killed at least 39 people and wounded at least 76, the deadliest attacks in the capital so far this year.
