The U.S. military said Sunday it had conducted airstrikes against ISIS near the Haditha Dam in western Iraq, the first time it has struck militants there. The dam is Iraq's second-biggest, and allowing it to fall under ISIS' control would potentially threaten the power and water supplies for much of the country's population.
"We conducted these strikes to prevent terrorists from further threatening the security of the dam, which remains under control of Iraqi Security Forces, with support from Sunni tribes," the Pentagon said in a statement.
The U.S. previously launched airstrikes to beat back ISIS fighters who had taken control of the Mosul Dam, Iraq's largest.
In an interview with Meet the Press Sunday, President Obama said he would address the nation on Wednesday to lay out his comprehensive plan for combating ISIS.
