Tensions between the United States and Iran are rising again as Tehran issues a strong warning over the Strait of Hormuz — one of the world’s most critical oil routes. Iran says it will not fully open the strait unless the US lifts its blockade on Iranian ports, accusing Washington of violating ceasefire terms and pushing “maximalist” demands. Despite brief progress after the Israel-Lebanon ceasefire, negotiations have stalled, and both sides are now signaling potential escalation. Iranian officials warn that if their ships cannot pass, others may also face restrictions — raising fears of a global oil supply disruption.
