Marco Rubio says the US is preparing for more strikes against Iran

Marco Rubio, a U.S. senator, has stated that the 'hardest hits' on Iran are still to come from the United States. He has been meeting with foreign ministers from the G7 group of nations and other allies, urging them to take stronger action against Iran, including stopping it from imposing tolls in a key international strait.

Rubio has also said the U.S. must be prepared for the probability that Iran will reject American diplomatic efforts. He has ordered U.S. diplomats to try to influence other nations to act against Iran and has told Arab ministers that a conflict could last several more weeks.
