BAGHDAD — The city of Fallujah is being hit by car bombs once again, five months after Iraqi Prime Minister Haider al-Abadi announced its liberation. Car bombs are not common in the northern and western cities of Iraq, as most attacks occur in Baghdad and the south of the country.

The latest attack happened Nov. 17, when a car bomb struck a wedding party held in Amiriyah Al-Fallujah, in Anbar province. The city has been the scene of fighting between the government forces and the Islamic State for two years now.

A video of the explosion quickly spread on social media. It showed dozens of guests dancing the traditional dabke at the wedding, celebrating the end of years of suffering under al-Qaeda and IS rule. But the bomb crushed the celebration and turned the wedding into a funeral, killing 17 people and wounding 30.

IS claimed responsibility for the attack in a statement, saying it targeted what it calls “Sahawat al-Radda,” groups funded and sponsored by disbelievers and apostates. According to the statement, a booby-trapped car had been parked near the wedding party.
