Officials say a suicide car bomber attacked a wedding near the Iraqi capital, killing at least 16 people.
The attack on November 17, in Anbar Province west of Baghdad, was the third this week in Iraq. Police officials said the explosion wounded more than 30 people.
There was no immediate claim of responsibility for the attack, though the recent spate of suicide bombings has been attributed to Islamic State militants.
Islamic State militants seized large swaths of territory in Syria and Iraq in 2014, but they've lost a significant part of that territory as Iraqi government forces, along with Shi'ite militias and Kurdish fighters, have pushed back.
The militants are battling to hold onto the last major stronghold in Iraq, Mosul, which is under a major assault led by Iraqi government forces.
Shi’ite fighters on November 16 said they had driven Islamic State extremists from an air base west of Mosul, threatening a key supply route from Syria.
