WASHINGTON — The U.S. military says that for the first time in the nearly two-year-old air campaign against the Islamic State, strike aircraft flew counter-ISIS missions from Navy warships in two different regions — the Mediterranean Sea and the Persian Gulf.

Marine Corps AV-8B Harriers on Thursday flew from aboard the USS Boxer in the Gulf to provide what Vice Adm. Kevin Donegan, commander of U.S. Naval Forces Central Command, called simultaneous strikes with combat planes flying off the USS Harry S. Truman in the Mediterranean.

The strike targets were not disclosed.

The Truman aircraft carrier strike group had been flying combat missions over Iraq and Syria from the Gulf, prior to moving into the Mediterranean about two weeks ago. It is due to return to the U.S. soon.
