BAGHDAD - A Shiite militant group is threatening U.S. interests in Iraq as part of the backlash over an anti-Islam film it has described as "heinous."

The leader of the Iranian-backed Asaib Ahl al-Haq said in an interview Thursday that the amateurish video that ridicules Prophet Muhammad was unforgiveable, and called on all Muslims to "face our joint enemy."

The militia leader, Qais al-Khazali, told The Associated Press that the video "will put all the American interests Iraq in danger."

The U.S. Embassy in Baghdad remains the world's largest American diplomatic mission, with an estimated 15,000 employees.

Asaib Ahl al-Haq led deadly attacks against U.S. troops before the American military withdrew from the country last year. It is funded and armed mainly by Iran.
