What happened

MSCIO Alert 88/26 said the master of an unnamed tanker heard two explosions while transiting about 9 nautical miles southeast of Kumzar, Oman. The vessel and crew were confirmed safe and no environmental damage was reported. MSCIO classified the report as an attack alert, but said the source and cause of the explosions remained unknown. Because the alert did not report a projectile sighting, impact or damage, this record is classified as an attack threat under investigation rather than a confirmed strike.

When cited sources give different casualty, damage or spill figures for this event, they’re reported side by side above rather than merged into one number. See how confidence levels work.
