US says Strait of Hormuz 'open to all' after Iran announces closure

US announced the Strait of Hormuz is "open to all vessels", hours after Iran declared it closed amid renewed tensions between both countries. "US forces are...prepared to ensure that freedom of navigation remains available despite unwarranted Iranian aggression," US Central Command said. US hit 140 Iranian military targets on Saturday after Iran attacked a ship in the Strait of Hormuz.
