The U.S. military has named the coalition operation against the Islamic State in Iraq and Syria (ISIS) "Inherent Resolve," Reuters quoted a U.S. military official as saying on Wednesday, Al Arabiya News reported.
The United States and five Arab allies launched in September air strikes against the militant group in Syria after a string of beheadings targeting Western nationals. Western nations are also targeting the group in neighboring Iraq.
ISIS has already claimed the establishment of the its so-called "caliphate" in territory it seized in both Syria and Iraq.
The United States has the support of some 40 countries in its push against the militant group.
