The Togo-flagged tanker Trend caught fire and stopped after a strike by Iran's Revolutionary Guard Navy in the Strait of Hormuz. The IRGC claimed the vessel attempted an "illegal crossing" prompted by the U.S. military, leading to the attack. UK Maritime Trade Operations recorded 3 targeted tankers in the waterway across Sept 17 and Sept 18, with two incidents occurring on the latter date.

Crew members from the struck vessels are safe, and no environmental impact has been reported. UKMTO issued two advisories on Sept 18 warning ships to transit with caution and report suspicious activity. The agency also released a delayed report of a separate tanker strike that occurred on Sept 16.
