U.S. begins airstrikes against Islamic State in Syria

Two U.S. defense officials identified the partner nations as Saudi Arabia, Jordan, the United Arab Emirates and Bahrain. One official described them as “full participants” in the airstrikes in Syria but did not give further details, saying it was up to those countries to fully disclose their roles.

Qatar also sent military aircraft to play a supporting role but did not carry out strikes, a third U.S. defense official said.
