The ongoing threat presented to Middle Eastern countries by ISIS fighters has resulted in thousands of airstrikes led by the United States in Iraq and Syria, home base of the militant group.
Leaders from Turkey were concerned enough about the dangers ISIS presents their country to call for a rare emergency meeting of NATO on Tuesday. It was only the fifth such meeting in NATO's 66-year history.
Turkey — which is north of Iraq and Syria — agreed to allow the U.S. to launch airstrikes from one of its air bases. See graphics below detailing the frequency and timeline of U.S.-led airstrikes against ISIS since December 18.
