Meanwhile, US Treasury Secretary Scott Bessent said that Washington was planning on imposing economic measures against Iran that have "never been seen" before, noting that it will be a combination of "economic isolation" and a continued blockade, with no goods moving in or out of Iranian ports, during an interview with Newsmax on Thursday.
