The U.S. military said Sunday it launched airstrikes around Haditha Dam in western Iraq, targeting Islamic State insurgents there for the first time in a move to prevent the group from capturing the vital dam.

The strikes represented a broadening of the U.S. campaign against the Islamic State militants, moving the military operations closer to the border of Syria, where the group also has been operating.

Speaking in Georgia where he's meeting with government and defense officials, U.S. Defense Secretary Chuck Hagel said that if the dam were to fall into the militant'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" including U.S. interests there.

At the same time, however, Hagel rejected the suggestion that the Haditha strikes opened up a new front in the war against the Islamic State group or that it represented an escalation of the U.S. military operations. He spoke at a press conference with Georgia Defense Minister Irakli Alasania.

Alasania, meanwhile, said Georgia expects to provide some assistance in the campaign against the Islamic State, saying that training and carrying out military exercises with the Iraqi forces are "things that come to our mind." He said Georgia can play a supporting role and there are plans to discuss the matter further.

U.S. officials said that while the Anbar Province dam remains in control of the Iraqis, the U.S. offensive was an effort to beat back militants who have been trying to take over key dams across the country, including the Haditha complex.

Hagel said the Iraqi government had asked the U.S. to launch the airstrikes and that Iraqi forces on the ground conceived the operation.

Anbar has for some time been a contested region between Iraqi forces and Islamic State militants backed by allied Sunni tribes. The situation deteriorated significantly in late December, and the militants took over parts of Ramadi and Fallujah.

The Iraqi government and allied tribes launched an offensive on Jan. 26 to wrest control of the cities back from the militants and sporadic clashes have continued around Fallujah and in some parts of Ramadi, with only limited success by Iraqi security forces. U.S. airstrikes could greatly boost their hand now.

"The dam is a critically important facility for Iraq," Hagel said, adding that the U.S. is continuing to explore all options for expanding the battle against the Islamic State into Syria.

Hagel spoke after a meeting with Alasania, the first of several sessions with government leaders. His visit comes on the heels of the two-day NATO summit in Wales.
