BAGHDAD — The Islamic State group on Tuesday claimed responsibility for a suicide attack on a funeral tent north of the Iraqi capital Baghdad the day before that killed 16 people and wounded 34 others.
The claim was made in a statement posted on a Twitter account frequently used by the extremist group. It did not mention the nationality of the attacker.
Monday's attack targeted the funeral of the father of two members of pro-government Sunni militias. The Islamic State group frequently targets Iraq's Shiite majority as well as Sunnis allied with the Shiite-led government.
The bomber showed up at the funeral disguised as a Shiite, with a religious flag and a portrait of a Shiite imam, according to Hussein Ali, a local resident who said he witnessed the attack.
In a separate incident, a Shiite militia commander was killed Monday by a sniper's bullet during fighting with Islamic State militants in the town of Duluiyah, about 75 kilometers (45 miles) north of Baghdad, said another senior militia commander.
Retired Brig. Gen. Abbas Hassan Jabr had joined the Badr Brigades, a powerful Shiite militia, after the IS group captured vast swaths of northern and western Iraq over the summer, said the commander, who spoke on condition of anonymity because his militia had not authorized him to speak to the press.
Iraq's Prime Minister Haider al-Abadi issued a statement hailing Jabr as "one of Iraq's heroes" and vowing that his death would increase "our determination to liberate all Iraq."
The Sunni IS group controls around a third of both Iraq and neighboring Syria, where it has declared an Islamic caliphate and imposed a violent form of Shariah law.
