Kurds retake Iraq's Mosul Dam from IS forces
Support from US helps regain strategically important energy facility.
Kurdish forces have regained control of Iraq's Mosul dam from Islamic State (IS) militants, reports say.
Ground forces supported by US air strikes launched the operation to take the dam on Sunday morning, the BBC said citing Kurdish officials.
IS militants seized control of the strategically important energy facility on the Tigris River on 7 August.
It is the largest dam in Iraq and supplies water and electricity to large parts of the north of the country.
Retaking the dam marks the biggest victory against the Islamic State since they swept across Iraq and Syria in June, declaring a Caliphate.
