A Norwegian chemical tanker, the Stolt Magnesium, catches fire after an explosion caused by an unidentified external device near Oman, according to the vessel’s manager and a crisis response report. The incident occurs at about 12:40 a.m. local time as the ship is sailing in the Arabian Sea off Oman’s coast. Stolt Tankers says the explosion is external and triggers a fire in the tanker’s engine room. The company adds that all seafarers are safe and accounted for and that the crew has begun fighting the fire. Another report from a crisis response network confirms the timing and describes the explosion as involving an unidentified external device that results in a fire in the engine room, citing information provided by Stolt Tankers. The available reports do not identify who or what caused the device, and no further details about damage beyond the engine-room fire are provided. The incident is reported in the context of broader regional tensions, though the accounts focus on the ship’s status and initial response rather than assigning responsibility.
