Transcript for Trump: ‘Certainly looking’ like Iran behind Saudi Arabia attack
First the latest on those tensions between the U.S. And Iran after saying the U.S. Was locked and loaded, ready to retaliate over that attack on key oil facilities in Saudi Arabia. President trump now appears to be taking a different stance saying he wants to avoid war. Chief global affairs correspondent Martha Raddatz has the latest. Good morning, Martha. Reporter: Good morning, robin. The secretary of state is squarely pointing the finger at Iran for the attacks and this morning, a senior official telling ABC that a nearly intact cruise missile and drone were found which could be important evidence, but the president seems in no hurry to definitively pin the blame on Iran or take any retaliatory action. The attack was brazen and highly sophisticated with more than 20 explosive-laden drones and nearly a dozen cruise missiles slamming into the oil facilities in Saudi Arabia leaving the world's largest refinery after a weekend of strong words and warnings, president trump now saying he suspects Iran was behind the attacks but telling our Jon Karl he wants to be certain. We're having some strong studies done but it's certainly looking that way at this moment anticipate we'll let I know. As soon as we find out definitive we'll let you know. Reporter: A senior administration official telling ABC news there is an unclassified statement ready to be released showing no doubt Iran carried out the strikes from its own soil including information that the attacks all came from the north. But the president was restrained in his comments on Monday. I don't want war with anybody. I'm somebody that would like not to have war. Reporter: In June after the U.S. Accused Iran of shooting down one of our drones, the U.S. Military was close to being locked and loaded for a retaliatory strike only to have the president shut it down because he said he was worried about loss of life. And there were those oil tankers the U.S. Said were struck by Iran, as well. So what is his message to Iran? I think I'll have a stronger message or maybe no message at all when we get the final results of what we're looking at but right now it's too soon to say. There's plenty of time. There's no rush. Reporter: This morning Iran is saying there is no chance that Iran's president will meet with president trump next week at the U.N. And while the administration is figuring out how to respond to these attacks, experts are saying that within weeks, gas prices could rise 10 to 25 cents a gallon, Michael. All right, Martha, the world is watching. Thank you so much for that.
