The U.S. is deploying a carrier strike group and a number of bombers to the Middle East to serve as a deterrent to Iran based on new intelligence that suggests allied interests and American forces could be imperiled, multiple U.S. officials said.

The Pentagon is sending a carrier and its accompanying ships as well as what is known as a bomber task force to the region in coming days in response to “a number of troubling and escalatory indications and warnings,” National Security Adviser John Bolton said in a statement Sunday…

The move to deploy additional forces to the region was based on a specific threat to U.S. forces operating in the region, according to a U.S. official. There have been indications recently of Iran or its proxies assembling and moving assets both on land and at sea, the official said…

Top officials gathered in the past couple of days for an emergency meeting to discuss new intelligence assessments on Iran. U.S. officials described the fresh concerns as troubling and that they specifically prompted them to restore some of the American military assets to the region which are no longer kept there on a regular basis as the U.S. has shifted more of its focus to other parts of the world.
