Rights group: Probe alleged airstrike on Iraq mosque

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.
