The official said that the U.S. has its eyes on Iranian activity in the region but is not necessarily concerned with it, reported The Huffington Post. He added that the attacks are taking place near the Iranian border, in a different part of Iraq than most U.S.-led coalition activity.

The official said that he believed that the Iranian bombing is unlikely to stop as long as the Shiite-dominated nation felt threatened by the IS. He also remarked that the activity will not call for a response from the U.S. unless the nation presents an immediate threat to the forces in the air.
