Iran’s parliament speaker and top negotiator, Mohammad Bagher Ghalibaf, told Al Jazeera the Strait of Hormuz will “never return” to its status prior to the US-Israeli war on Iran.

In an interview published on Wednesday, he said Iran and Oman reached an understanding to oversee the waterway as part of Tehran’s seven-point proposal to end the eight-month conflict. Iran’s conditions include lifting the naval blockade and sanctions, the release of frozen funds, ending fighting on all fronts and an explicit announcement of an end to the war. Ghalibaf said Tehran delivered its response to the US through a Qatari mediator and that “the ball is now in the American court.” According to him, US officials asked Russian President Vladimir Putin to mediate direct negotiations with Tehran during a visit to Moscow.
