Iran’s Islamic Revolutionary Guard Corps reported that a second supertanker struck a naval mine and caught fire in the Strait of Hormuz on Saturday, and Iran’s navy said an oil tanker caught fire in the Sea of Oman, according to Al Jazeera.

United States Central Command (Centcom) said the “vast majority” of Iran’s attempted attacks on ships in the strait failed and that the waterway remains open, and spokesperson Tim Hawkins told Fox News that about 97 percent of vessels trying to cross the strait had done so without being struck, many with US military protection, according to Middle East Eye. Foreign Minister Abbas Araghchi said Tehran presented a concrete seven-day plan to reopen the Strait of Hormuz, conveyed through Qatar, according to Iranian state broadcaster Press TV, cited by Middle East Eye; he told RT that, if the necessary conditions are met, the Strait can be reopened and normal maritime passage restored within seven days, in exchange for Washington lifting its naval blockade, easing restrictions on Iranian oil exports and releasing frozen Iranian assets.
