The United States has launched the first of its airstrikes inside Syria, the Pentagon confirmed Monday night, as the U.S. ramps up its offensive targeting ISIS targets there. A Pentagon spokesman confirmed that the strikes had begun "using a mix of fighter, bomber and Tomahawk Land Attack Missiles," but it wouldn't give further details. NBC News reported that the U.S. military plans to strike up to 20 targets — logistics, fuel and weapons depots; training sites; troop encampments; command and control sites; and headquarters for the Sunni fighters.
