An “unknown projectile” struck and caused a fire on an oil tanker off the coast of Oman near the Strait of Hormuz on Monday, British maritime security agency United Kingdom Maritime Trade Operations (UKMTO) said. The incident occurred near one of the world’s most important energy shipping routes, despite a ceasefire between the United States and Iran and ongoing efforts to secure a lasting peace agreement. The maritime agency said the incident took place eight nautical miles east of Limah, Oman.
