Iran has temporarily reopened the Strait of Hormuz following a US-brokered ceasefire between Israel and Lebanon, allowing a convoy of tankers to pass for the first time in seven weeks of war. US President Donald Trump has expressed optimism about ongoing weekend negotiations while warning that a ceasefire may not extend past Wednesday without a deal, as a US naval blockade on Iranian ports persists. Several of Trump's claims about negotiation progress are disputed by Iran and contradicted by reports.
