A ceasefire between the US and Iran appears to be uncertain, with some reports indicating talks have ended without agreement and others suggesting a plan is still being considered. The two sides have exchanged strikes across the Middle East for at least two days, and Iran has vowed to continue fighting. The US has also taken steps to increase pressure, with a potential blockade of the Strait of Hormuz mentioned, amid ongoing tensions and conflicting reports on the status of a potential deal.
