The Joint Maritime Information Centre (JMIC) kept the Strait of Hormuz threat level at “severe” on Sunday as it reported continued activity by Iran’s Islamic Revolutionary Guard Corps (IRGC) around commercial vessels.
JMIC cited attempted attacks or harassment, unmanned aerial vehicle overflights, surveillance of merchant shipping and occasional radio hails. It reported no confirmed attacks or disruptions in the waterway during the previous 72 hours.
Commercial traffic remained below 2025 levels. US Coast Guard data cited by JMIC showed an average of about 30 vessel transits per day during the same 72-hour period.

Separate claims emerged from Iranian-linked sources on Sunday. Revolutionary Guards-affiliated Fars News Agency cited local sources as saying a sea-launched cruise missile was fired at a vessel travelling on what it described as an unauthorised route.
The material does not identify the vessel or confirm damage. IRGC spokesperson Hossein Mohebbi also claimed the Guards Navy had seized a second US underwater vehicle in the Strait.
Writing on X, he posted an image of what he identified as an Mk 18 Mod 2 Kingfish autonomous underwater vehicle. No US response to that claim appears in the supplied material.

JMIC said continuing activity indicated Iranian forces were maintaining a presence along major transit routes while pressure on shipping persisted. Its latest assessment left the Strait of Hormuz at the “severe” threat level.
