CloseOn Monday, US Treasury Secretary Scott Bessent, announced an "economic D-day" against Iran, with further sanctions on the regime and countries doing business with it.
Iranian Economy Minister Ali Madanizadeh said Tehran was "fully prepared" for the sanctions, which he said would lead to "another defeat" for the US.
