The U.S. military announced a blockade of Iranian Gulf ports starting Monday at 7:30 PM IST, controlling ships entering and leaving Iran while allowing non-Iranian vessels through. The United Kingdom and Australia declined participation. Britain supports maintaining open navigation. Australia said it received no blockade request. Trump stated Iran could negotiate, though later said he didn't care if talks resumed. Iran's president told Putin a balanced agreement was possible if the U.S. follows international law.
