WASHINGTON (AP) " The White House says the U.S. is deploying additional military resources to send a message to Iran.

White House national security adviser John Bolton said Sunday that the U.S. is deploying the USS Abraham Lincoln Carrier Strike Group and a bomber task force to the U.S. Central Command region." That area includes the Middle East.

Bolton says the move is in response to what he calls "a number of troubling and escalatory indications and warnings." He isn't providing details, but says the U.S. wants to send a message that "unrelenting force" will meet any attack on U.S. interests or those of its allies.

He says the U.S. isn't looking to go to war with Iran but that it's fully prepared to respond to any attack.
