Recordings from the crew of a merchant vessel trapped near the Strait of Hormuz
show Iran's Islamic Revolutionary Guard Corps navy and US aircraft radioed
warnings to ships on the evening of the 30th local time. The IRGC told vessels
in the Persian Gulf and Gulf of Oman the strait remains closed and only ships
granted IRGC permission and navigating on Iran-designated routes may transit,
warning violations would severely endanger navigation. The IRGC added any US
Navy attempt to interfere with management of the strait or disrupt shipping
order would be met with severe military response.
