Eighteen maritime security incidents logged in week 1-7 June, Hormuz cluster widens
Palaemon's weekly maritime security report logs 18 incidents in the 1-7 June window, with four in the Northwest Indian Ocean — including a US Hellfire strike on a tanker engine room near Kharg Island and a boarding of a sanctioned tanker carrying 1.9 million barrels southwest of Sri Lanka.
Eighteen maritime security incidents were recorded in the 1-7 June 2026 window, according to the latest weekly report from Palaemon Maritime Security. Four sat in the Northwest Indian Ocean, seven across Europe and the Black Sea, three across Southeast Asian anchorages, one in the Gulf of Aden, and one in the Americas. The Gulf of Guinea logged no specific incidents this week, though Palaemon keeps anchorage petty theft and robbery on a low-but-live rating.
Two of the Northwest Indian Ocean items deserve sit-down attention. On 2 June a US aircraft fired a Hellfire missile into the engine room of a Botswana-flagged oil tanker approaching Kharg Island. On 5 June US forces boarded a sanctioned tanker carrying what Palaemon describes as 1.9 million barrels of Iranian crude southwest of Sri Lanka. On 6 June Iran launched a ballistic missile attack against a US facility in Bahrain, with six interceptions reported. Operational guidance in the report recommends avoiding the Strait of Hormuz Traffic Separation Scheme until further notice.
In Southeast Asia, the headline event was a 3 June armed robbery aboard the Maltese-flagged containership CMA CGM Valparaiso at Manila Anchorage, where four robbers armed with three guns and a knife held the duty watchman at gunpoint. Two attempted boardings on bulk carriers in the Philip Channel rounded out the regional total. In Europe, Ukrainian UAV strikes continued against Russian naval and terminal assets — most notably damage to the patrol vessel SVETLYAK off Crimea on 6 June and a multi-UAV strike on the St Petersburg Oil Terminal tank farm on 3 June, with the corvette BOIKIY also hit while in dry dock.
What it means for owners
- Treat the Hormuz approach as an active US enforcement zone now, not just an Iranian risk vector — tanker masters need updated brief packs covering US-led boarding protocol and sanctioned-cargo documentation.
- Manila Anchorage and the Philip Channel remain on the watch-deck list; ensure ISPS drills, watchman pairing and a current K&R certificate are documented before the next vetting visit.
