Defense sources told Fox News that a "lengthy, multi-phase operation" is expected to retake the dam and it began Saturday morning local time. 

The ground operation is being carried out with Iraqi army cooperation and is being billed as a joint Kurdish-Iraqi-US operation, sources said. 

A high-level Kurdish official in the Mosul area told Fox News that Peshmerga fighters have taken the town of Teleskof inside ISIS-held area in northern Iraq as well as a few other surrounding villages Sunday.

U.S. Central Command said Saturday that a mix of U.S. fighter and remotely-piloted aircraft executed nine strikes as part of its humanitarian efforts in Iraq and to protect American personnel and facilities.

The strikes destroyed or damaged four armored personnel carriers, seven armed vehicles, two Humvees and an armored vehicle, officials said.

A senior U.S. official told Fox News early Saturday that the strikes were to protect Iraq’s critical infrastructure and that the U.S. executed them at the request of the Iraqi government, which thinks Islamic State forces can no longer maintain the dam. If the dam should fail, up to 12 feet of flooding at the U.S. Embassy and the major cities of Baghdad and Mosul could occur, officials say.
