The US will send a Terminal High Altitude Area Defense (THAAD) system and additional Patriot air defense missile system battalions to the Middle East, the Pentagon said on Saturday, in response to recent attacks on US troops in the region.
"Following detailed discussions with President Joe Biden on recent escalations by Iran and its proxy forces across the Middle East Region, today I directed a series of additional steps to further strengthen the Department of Defense posture in the region," Defense Secretary Lloyd Austin said in a statement.
Austin said he was placing additional troops on prepare-to-deploy orders but did not say how many.
The United States has sent a significant amount of naval power to the Middle East in recent weeks, including two aircraft carriers, their support ships and about 2,000 Marines.
Washington is on heightened alert for activity by Iran-backed groups as regional tensions soar during the Israel-Hamas war.
The deployments come two years after Biden's administration withdrew air defense systems from the Middle East, citing a reduction in tensions with Iran.
