U.S. intelligence chief warns Iran escalated plots against American personnel

U.S. intelligence chief Jay Clayton warned Secretary of State Marco Rubio that Iran has "substantially increased efforts to target U.S. personnel" abroad, with lethal plots reaching "advanced stages" in the Middle East and other countries. The unclassified memo, obtained by CBS News, comes as the State Department adjusts embassy staffing across the region and the U.S. military reduces its footprint there, citing threats from Iran and Iranian-backed Houthi militants in Yemen. Specific targets or countries were not identified. The warning follows the State Department ordering non-essential personnel to depart Saudi Arabia and other embassies adopting restricted operations status. President Trump suggested Friday the U.S. could launch another military operation against Iran if no agreement is reached.
