Iran and the Gulf Arab state of Oman have made progress toward a deal to reopen the Strait of Hormuz, a potential breakthrough that could help wind down the war in the Middle East, regional officials said Tuesday. The officials spoke on condition of anonymity to discuss the sensitive negotiations unfolding behind closed doors. The strait was an open international waterway before the U.S. and Israel attacked Iran on Feb. 28. A U.S. official familiar with the negotiations said that any “temporary” routes established through the strait would not involve approvals by Iran or charges. In an exchange with reporters on Monday, Trump reiterated his public stance that he’s opposed to tolling in the strait.
