Iran says two oil tankers catch fire in Strait of Hormuz

Iran's Revolutionary Guards reported Tuesday that two oil tankers caught fire in the Strait of Hormuz after traveling on unauthorized routes, escalating tensions in the strategic waterway that carries about one-fifth of global oil. The Guards said a super tanker struck a naval mine, causing an explosion, while a second tanker under US military escort had an incident during a covert passage. Tehran has restricted traffic since late February's Middle East war, prompting a US naval blockade and assistance to tankers. The Guards did not identify the vessels' names or origins. Recent weeks have seen multiple Iranian announcements of ships catching fire, with Tehran citing mines, though the US military claims all mines were cleared from the waterway.
