US airstrikes target militants threatening Haditha Dam (+video)
US airstrikes have expanded into Iraq's western Anbar province in hopes of keeping the nation's second-largest hydroelectric facility out of the hands of Islamic State insurgents.
Baghdad — US warplanes launched four air strikes against Islamic State militants threatening western Iraq's Haditha Dam early on Sunday, witnesses and senior officials said, broadening Washington's campaign against the fighters.
The leader of a pro-Iraqi government paramilitary force in the west said the strikes wiped out an Islamic State patrol trying to attack the dam - the country's second biggest hydroelectric facility which also provides millions with water.
"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 Baghdad," Sheik Ahmed Abu Risha told Reuters.
The strikes were Washington's first reported offensive into Iraq's western Anbar province since it started attacks on Islamic State forces in the north of the country in August. The move brought its planes closer to the border with Syria.
US Defense Secretary Chuck Hagel said they had been carried out at the request of the Iraqi government.
"If that dam would fall into ISIL's (Islamic State's) hands or if that dam would be destroyed, the damage that that would cause would be very significant and it would put a significant, additional and big risk into the mix in Iraq," he told reporters during a trip to Georgia's capital Tbilisi.
Islamic State has overrun large areas of Iraq and Syria and declared a cross-border Islamic caliphate.
Iraqi government forces and a small number of Sunni militias have been confronting Islamic State and other fighters in Anbar since January.
Iraq's outgoing Foreign Minister Hoshiyar Zebari welcomed the growing US air campaign and said Islamic State was trying to control strategic assets, including dams across Iraq.
The militants seized control of a dam outside Falluja in April and flooded areas on the rural outskirts of western Baghdad, displacing thousands of people.
It abandoned that dam, but went on to take control of Mosul dam, Iraq's biggest, last month, before being forced out by US air strikes and Kurdish fighters.
US President Barack Obama said last week key NATO allies stood ready to join Washington in military action to defeat Islamic State in Iraq and vowed to 'take out' the leaders of a movement he said was a major threat to the West.
However, Pentagon officials have maintained airstrikes can only go so far in the fight against the Islamic State.
“If we’ve learned nothing over 13 years of war, it’s you can’t completely eliminate extremism anywhere through simply kinetics, through airstrikes alone,” Rear Adm. John Kirby said in a Pentagon briefing last month.
