Iran's new supreme leader orders immediate response to any threat, with no geographic limit

Iran's Supreme Leader Mojtaba Khamenei has ordered an "immediate and effective" response to any enemy threat, with no geographical limits. The order followed Iranian claims of striking an unmanned vessel near the Strait of Hormuz and of tankers catching fire, while a Qatari delegation visited Tehran amid reports of a US letter aimed at restarting talks. The war that began with Israeli and US attacks in February remains unresolved, and UNCTAD warns that shipping disruption is raising freight, fuel and food costs, so the confrontation involving Israel, Iran and the United States still carries risk of wider regional war.
