Transcript for Pentagon to send 1,000 troops to Middle East
developments in this escalating situation with Iran intensifying this morning. The U.S. Now saying it will send about a thousand more troops to the Middle East and comes after those attacks on those oil tankers and Iran is threatening to break the terms of that nuclear deal within days, of course, the U.S. Had pulled out of that deal. Let's get to Martha Raddatz live in Washington with the overnight developments. Martha, good morning. Reporter: Good morning, David. This is the second time in a matter of weeks that the U.S. Military is sending additional forces to the region to counter what they see as the threat from Iran but the Iranians are not backing down. The U.S. Forces at least 1,000 more come at the request of central command. For what they call air, naval and ground-based threats from Iran. The additional forces increase intelligence, reconnaissance, surveillance and force protection and the U.S. Declassifying new color images from that tanker attack in the gulf of Oman which shows the damage close up and them removing an unexploded mine from one of the tankers. No evidence of the Iranians placing them on the ships. This comes as Iran is threatening to exceed the limits allowed for nuclear fuel unless Europeans give relief from the sanctions. The white house calling that nuclear blackmail and prompting that president trump will never allow Iran to develop nuclear weapons but several European nations are demanding more evidence. If you continue to thump your chest, at some point somebody may cross the line and throw a punch. That's a where the danger comes. Reporter: The U.S. Defense secretary is making clear this morning that the U.S. Is not seeking conflict with Iran, even with the addition of those troops which combined with the request several weeks aek will number more than 2500, robin. Quite an escalation. Thank you.
