Breaking news :U.S. airstrikes hit ISIS targets inside Syria

 They're the first strikes against the terror group inside the country since President Barack Obama's announcement this month that he was prepared to expand the American efforts beyond targets in Iraq.

All foreign partners participating in the strikes with the United States are Arab countries, a senior U.S. military official told CNN. Those nations are Bahrain, Saudi Arabia, the United Arab Emirates and Jordan.

Diplomatic sources told CNN that Qatar was also involved, though it was not clear whether Qatar actually conducted airstrikes .

The U.S. and "partner nation forces" began striking ISIS targets using fighters, bombers and Tomahawk missiles, Pentagon spokesman Rear Adm. John Kirby said, though he didn't specify a geographic location.

Citing the ongoing operations, Kirby said the Pentagon would not provide additional details immediately. But a U.S. military official said the strikes are meant to target the ability of ISIS to command and control, resupply and train.
