The Latest on developments in Iraq as the battle for Mosul enters its second week (all times local):

9:10 a.m.

Iraqi special forces have begun shelling Islamic State positions near Mosul in the latest phase of a massive operation to retake the militant-held city.

Maj. Gen. Haider al-Obeidi says the shelling began early on Monday northwest of Bartella, a historically Christian town 15 kilometers (9 miles) to the east of Mosul. Iraqi special forces retook Bartella last week.

The campaign to retake Mosul comes after months of planning and involves more than 25,000 Iraqi troops, Kurdish forces, Sunni tribal fighters and state-sanctioned Shiite militias. It is expected to take weeks, if not months, to drive IS out of Iraq's second largest city, which is still home to more than a million people.

A rights group is urging a probe into a suspected airstrike in northern Iraq that killed at least 13 during last week's battles for Mosul.

Human Rights Watch said on Monday that the explosion struck the women's section of a Shiite mosque in the town of Daquq and appeared to have been caused by an airstrike.

Residents believe it was an airstrike because of the extent of the destruction and because planes were heard flying overhead. It happened on Friday amid a large Islamic State assault on the nearby city of Kirkuk.

The U.S.-led coalition battling IS and the Iraqi air force are the only parties known to be flying aircraft over the country. Both are engaged in the massive operation to take the Islamic State-held city of Mosul.
