Seven weeks into the US-Iran war, the Strait of Hormuz combat zone has seen over 22 UK Maritime Trade Operations (UKMTO)-reported vessel and port incidents since February 28, including three attacks on March 11 alone: an Iranian unmanned surface vessel struck the Thai-flagged MAYUREE NAREE cargo ship in the strait, causing fire and evacuation; a drone hit another cargo ship there; and a drone damaged a bulk carrier off Dubai. US Central Command sank over 60 Iranian naval vessels on March 11, including all four IRGC Navy Soleimani Class warships, while one successful US Navy-escorted tanker transit occurred on March 10. Attacks escalated to direct strikes on port infrastructure and tankers, with Iranian drones hitting Oman's Salalah port on March 28, a Kuwaiti oil tanker at Dubai port on March 31, and a missile striking an oil tanker off Qatar on April 1.
