According to UKMTO, a small boat attached two explosive devices to the hull above the waterline. The blasts caused an engine-room fire and temporarily disabled the vessel as it sailed out of the Strait of Hormuz.
The body says the fire is extinguished, the crew are safe and no environmental impact has been reported. Responsibility for the attack has not been established. This incident should be distinguished from other alerts that day, including a tanker struck by a projectile; it does not confirm Iranian claims about mines.
