Iraqi officials say a suicide bomber targeting a Sunni mosque west of Baghdad killed 14 and wounded 32 Monday night.
The attack struck an Abu Ghraib mosque as worshipers gathered to pray after breaking their fast during the holy month of Ramadan.
Police and hospital officials confirmed the tolls and spoke on condition of anonymity as they were not allowed to release information.
No group has yet claimed responsibility for the attack, but it does not necessarily bear the hallmarks of ISIS group attacks.
ISIS attacks – of which Baghdad and surrounding areas experienced an uptick in last month – generally target Shiite civilians and security infrastructure.
On Sunday, Iraqi forces declared Fallujah fully liberated from ISIS after the operation to retake the city was launched late last month.
