Iran has announced the closure of the Strait of Hormuz, citing ceasefire violations related to Israeli attacks in Lebanon. This declaration comes as US-Iran talks are set to begin in Switzerland, with negotiators on their way despite the escalating situation. While Iran claims military control over the strait is asserting dominance, US officials counter that commercial vessels are still transiting through the waterway without disruption. The announcement has led to increased anxiety in oil markets, with experts warning of potential pressures on oil prices and significant hurdles for the fragile agreement between Iran and the US. As tensions continue, the international community is closely monitoring the unfolding situation.
