Transcript for US Launches Airstrikes in Syria Against ISIS
And good morning, America. Right to the breaking news. The first American air strikes in Syria. New front in a long war. Missiles fired from warships dropped by air. Most are in the Isis stronghold of raqqah. But also a new terror group inside Syria called corasan. How that active plot targeting America was stopped. Surprising developments. Our ABC news security team up all night tracking this story. Start with Martha Raddatz who's in Washington. Reporter: Good morning. This is a major escalation in the fight. It may not have been shock and awe, but the wave of air strikes in Syria was the biggest we have seen in a single day since the U.S. Began attacking Isis in August. We did not do it alone and not just attacking Isis. The strikes were launched from the air and the sea. Missiles and precision-guided bombs from U.S. Stealth bombers, stealth fighters and armed drones pummelling 22 targets in Syria with 47 tomahawk missiles fired from Navy warships in the persian gulf and red sea. Very different than Iraq. This is almost like a desert storm. Lots of fire power, everything the United States has, all our best gear into this fight. It's a high-threat environment. Reporter: 14 of the targets were aimed at Isis headquarters, supply depots, command and control centers and financial centers. Stretching from raqqah where the Americans and british hostage were executed, and across to the east of the Iraq border. But eight additional Al Qaeda targets were hit to disrupt what the U.S. Called an imminent trk against the U.S. By the corasan group. From Jordan, Saudi Arabia, Bahrain, Qatar and the united Arab emt rates helped with the attack against Isis. This is the most participation from Sunni Arab nations dropping bombs on other Sunnis. It's quite remarkable. Reporter: The U.S. Has been flying surveillance missions, picking out the targets for the mission. It was not a mission without risk. Syria has sophisticated anti-aircraft systems. But it is unlikely the Assad regime would want to fire on the U.S. Or Arab countries since he wants to get rid of Isis. They were notified of the attacks, to decon conflict the aircraft not to strike.
