Islamist rebels have brought in specialists to make repairs to the country's biggest dam so that power can be restored to the city of Mosul in northern Iraq, according to an engineer.
He told Reuters: "They are gathering people to work at the dam."
A dam administrator added that militants were putting up the trademark Islamic State black flags and they were patrolling with flatbed trucks mounted with machine guns to protect the facility they seized from Kurdish forces earlier this week.
Mosul, Iraq's biggest city in the north has been suffering from power outages and water shortages.
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.
