Iran and the United States exchanged fire on Thursday, intensifying attacks that have persisted since the weekend and all but torn up the truce that paused fighting last month. While the two countries wrestle for control of the Strait of Hormuz, Iran signalled that it could prod Houthi allies in Yemen to close the Bab al-Mandeb Strait at the mouth of the Red Sea, another key oil route.
