In September 2014, GCC members Saudi Arabia, Bahrain, UAE and Qatar, plus pending member Jordan, commenced air operations against Islamic State of Iraq and the Levant (ISIL) in Syria. Saudi Arabia and the UAE, however, are among the nations that oppose the Muslim Brotherhood in Syria, whereas Qatar has historically supported it. They also pledged other support including operating training facilities for Syrian rebels (in Saudi Arabia) and allowing the use of their airbases by other countries fighting ISIL.
