NEW: The United States and Iran have reached an agreement in principle on a preliminary deal that would reopen the Strait of Hormuz and commit Iran to disposing of its stockpile of highly enriched uranium, enriched to 60%. The deal still requires approval from President Trump and Iran's Supreme Leader. Under the framework, Iran would clear mines from the strait and allow free passage of commercial shipping, while the US would lift its naval blockade of Iranian ports. Iran would also be allowed to resume oil sales. A 60-day ceasefire extension is part of the package, with broader nuclear issues deferred to later talks. No final agreement has been signed.
