US military operations against Islamic State in Iraq have cost an average of $7.5 million per day since they began in mid-June, the Pentagon said on Friday, a figure that means the department has spent more than $500 million on the conflict.
Rear Admiral John Kirby, the Pentagon press secretary, told a briefing the expense of US operations against Islamic State in Iraq had varied since US forces became involved on June 16 but on average "it's costing us about $7.5 million per day."
"As our op (operational) tempo and as our activities have intensified, so, too, has the cost," Kirby said, noting that the figures were based on a snapshot of expenses between June 16 and Aug. 26.
