Suicide attack kills at least 16 at Iraq wedding: Officials

The attack, which took place in Amriyat al-Fallujah, a town in Anbar province 40 kilometres from the capital, also left more than 30 people wounded.

There was no immediate claim of responsibility for the attack, but the Islamic State jihadist group frequently carries out suicide bombings targeting civilians in Iraq.

The attack came three days after twin suicide bombings claimed by IS struck Fallujah, a city northwest of Amriyat al-Fallujah, killing at least 15 people.

IS overran large areas north and west of Baghdad in 2014, but Iraqi forces have since regained much of the territory they lost, and they are now battling to oust the jihadists from Mosul, the last city they hold in the country.

While IS has been pushed back from areas it once held in eastern and central Anbar, the jihadist group still controls several towns in the province's west.
