Iraq's speaker of parliament says an attack claimed by the Islamic State group in the country's eastern Diyala province that killed 86 people, mainly Shiites, has struck an "ugly sectarian chord."

Salim al-Jabouri said Saturday that the Sunni militant group seeks to destabilize the country by carrying out criminal acts and targeting innocent civilians.

Diyala police say a small truck detonated in a crowded marketplace in the town of Khan Beni Saad Friday night as locals gathered to mark the end of the Islamic holy month of Ramadan. Many women and children were killed in the attack. At least 86 people were injured in the attack.

The militant group claimed responsibility for the attack in a statement posted on Twitter accounts associated with the Islamic State group.
