The fire has since been extinguished and the vessel is underway; crew are safe; no environmental impact or damage assessment reported. @UK_MTO posted the PDF ~10:30Z. Osint613 relayed the advisory and earlier flagged VIIRS Day/Night Band imagery of a bright spot ~31.5 km east of Khasab, Oman, as a possible correlating fire signature (attacker unattributed; vessel name unpublished). Distinct from live Warning 142-26 / CAPE DAO (evt_b81246a3).
