Explosives attached to the outside of a tanker by fighters in a speedboat damaged the larger vessel’s engine in the Strait of Hormuz, the first attack of its sort in the current conflict and a tactic Iran has used before against commercial shipping. An unspecified number of people in a small boat carried out the attack Thursday, according to UK Maritime Trade Operations, which monitors shipping security. No one was injured in the explosion above the waterline, and although a fire temporarily disabled the vessel, it continued on its journey, the organization said. #oott bloomberg.com/news/articles/…
