What UKMTO reported on Saturday
The United Kingdom Maritime Trade Operations said in a report issued on Saturday that it had received a delayed report of a tanker being struck by an "unknown projectile" 68 nautical miles northeast of Jubail, Saudi Arabia. The incident itself happened on Friday.
According to UKMTO, all crew members were reported safe and had been evacuated from the vessel, and no environmental impact had been reported at the time of the notification. Reuters, which carried the UKMTO report, gave no further details about the ship's identity or its cargo.
Jubail sits on Saudi Arabia's eastern Gulf coast, which makes this a different theatre from the recent spate of incidents in and around the Strait of Hormuz. GlobalDeskNews has reported this week on a supertanker said to have struck a naval mine in the strait and the MT ST 3 tanker hit while carrying 15 Indian crew. Saturday's report extends the danger zone to waters off Saudi Arabia's own coast.
A second report: rocket-propelled grenade attack from a small boat
UKMTO later issued a second report on Saturday describing another attack in the same area. According to that report, a tanker was attacked by a rocket-propelled grenade fired from a small boat 78 nautical miles northeast of Jubail on Friday, damaging the vessel's aft port quarter.
All crew members were reported safe in this second incident as well, UKMTO said, while the full extent of the damage and any environmental impact was not yet known.
Crucially, Reuters said it could not immediately establish whether the two UKMTO reports referred to the same incident or two separate ones. The locations differ slightly — 68 versus 78 nautical miles northeast of Jubail — and the described weapons differ, but with both incidents dated Friday in the same stretch of water, the question remains open.
The vessel: what maritime security agencies say
UKMTO itself did not name the vessel. But maritime security agency Vanguard identified the ship as the Marshall Islands-flagged Safeen Principal crude oil tanker, according to a report carried by AFP, saying it had lost power and suffered an engine-room fire.
That identification has not been independently confirmed by the vessel's owners or flag state, and no official statement about the ship's identity has been issued. Until one appears, the name should be treated as a single agency's assessment rather than established fact.
What remains unknown
Almost everything beyond UKMTO's reports remains unverified. No group has claimed responsibility, and no government has publicly identified an attacker. The "unknown projectile" wording is UKMTO's own and points at no particular party.
It is also unclear whether Friday saw one attack described two ways or two genuinely separate attacks. Reuters explicitly flagged that it could not resolve the question. And for the second incident, the full scale of the damage — beyond the reported strike to the aft port quarter — is still unknown.
Why it matters
The Gulf's eastern waters are among the most strategically sensitive on earth. AFP noted that about one-fifth of global oil exports passed through the Strait of Hormuz before the current war, which began with US and Israeli strikes on Iran on February 28, and that oil prices have soared during the conflict. An attack off Jubail — inside the Gulf itself, off Saudi Arabia's coast — signals that commercial shipping is no longer safe even far from the strait's chokepoint.

What happens next
Three things matter next: whether the vessel's owner or flag state confirms the attack, whether any party is ever publicly identified as responsible, and whether shipping companies and insurers alter how they operate in the Gulf.

Frequently Asked Questions
What happened to the tanker off Jubail?
According to the United Kingdom Maritime Trade Operations, a tanker was struck by an "unknown projectile" 68 nautical miles northeast of Jubail, Saudi Arabia, on Friday. UKMTO issued its report on Saturday, saying all crew were safe and evacuated with no environmental impact reported.
Was there a second attack near Jubail?
UKMTO issued a second report on Saturday describing a rocket-propelled grenade attack from a small boat 78 nautical miles northeast of Jubail on Friday, which damaged the tanker's aft port quarter. Reuters noted it could not immediately establish whether this was the same incident as the first report or a separate one.
Which ship was attacked?
UKMTO did not name the vessel. Maritime security agency Vanguard identified it as the Marshall Islands-flagged Safeen Principal crude oil tanker, saying it lost power and suffered an engine-room fire. That identification has not been confirmed by the ship's owners or its flag state.
Who attacked the tanker?
Unknown. UKMTO described the weapon only as an "unknown projectile," no group has claimed responsibility, and no government has publicly identified an attacker. Any attribution at this stage would be speculation.
Were there any casualties or an oil spill?
No. UKMTO said all crew members were reported safe and evacuated in both reported incidents, and no environmental impact had been reported for the first. For the second incident, the full extent of damage and environmental impact was not yet known.
Where is Jubail and why does this location matter?
Jubail (Al Jubail) sits on Saudi Arabia's eastern Gulf coast. An attack there extends the threat to commercial shipping beyond the Strait of Hormuz into the Gulf itself, at a time when AFP notes oil prices have already soared during the wider conflict.
