The fight against the Islamic State in Iraq and Syria (ISIS) has exceeded $8 billion in total cost, the Pentagon said Thursday.
The figure, which was accurate as of June 15, amounts to an average of $11.8 million a day for 678 days of operations, or about $354 million per month.
The U.S. began airstrikes against the terrorist group in August 2014, after the terrorist organization stormed into Iraq from Syria and took over huge swaths of territory.
Since then, a U.S.-led military coalition has helped Iraqi forces retake almost half of that territory.
The coalition is gearing up to retake Mosul, ISIS's stronghold in Iraq, and then Raqqa, its main base in Syria. There is no timeline yet as to when that might occur.
