US fighter planes have pounded Isis militant positions as part of a joint military operation to retake Iraq's largest dam, officials told NBC News.
American officials told the station that FA-18 fighter bombers and armed drones were launching airstrikes and offering air cover to Iraqi and Kurdish forces fighting to regain control of the Mosul Dam.
Control of the dam, which was seized by Isis fighters on August 7 could give the group the ability to flood cities and cut off vital water and electricity supplies.
The Iraqi capital Baghdad lies downstream of the dam on the Tigris river.
Kurdish Peshmerga fighters have emerged victorious in the battle for Mosul Dam, but the question is - what will their next move be?
An ITV News team at Mosul Dam was with victorious Kurdish Peshmerga fighters at the complex earlier today.
ITV News joined a Kurdish unit fighting Islamist militants near Irbil and found them using tanks from the 1950s and short on ammunition.
