Iraqi forces say they have cleared Islamic State (IS) militants from a wide area around the strategic Haditha dam, helped by US air strikes, BBC reported.
The jihadists have repeatedly tried to capture the dam in western Anbar province from government troops and their Sunni militia allies.
The action marked a widening of US air strikes which have previously been in support of Kurdish forces in the north.
US President Barack Obama is to reveal a strategy on Wednesday to defeat IS.
The leader of a pro-Iraqi government paramilitary force in western Iraq said the air strikes wiped out an IS patrol trying to attack the dam.
"They (the air strikes) were very accurate. There was no collateral damage. If Islamic State had gained control of the dam, many areas of Iraq would have been seriously threatened, even (the capital) Baghdad," Sheik Ahmed Abu Risha told Reuters.
Iraqi forces then launched a drive against militants in the Haditha area and regained ground.
"Joint forces backed by air support and tribesmen launched a wide attack to clear the areas surrounding the Haditha district," security spokesman Lt Gen Qassem Atta told AFP news agency.
Troops and militia also retook Barwana, east of Haditha, from IS fighters, who abandoned their weapons and vehicles in their retreat, AFP reported.
