The United States struck Iran after attacks on vessels in the Strait of Hormuz, according to a report citing Axios. The report linked the U.S. action to the maritime attacks in the critical shipping corridor. Details on the scope of the strikes and the timing of the vessel attacks were not provided in the report. The Strait of Hormuz is a strategic chokepoint for global energy and commercial shipping, and military action in the area can quickly raise regional tensions. The report did not include any immediate official confirmation or a response from Iran.
