Iran has declared that it has closed the Strait of Hormuz in response to alleged ceasefire violations related to Israeli strikes in Lebanon. This announcement comes as U.S. negotiators, led by Vice President JD Vance, travel to Switzerland for peace talks aimed at de-escalating tensions. While Iran insists that the strait is effectively shut, U.S. officials dispute this claim, stating that commercial vessels continue to flow through the vital waterway. The situation remains fluid, with both sides making opposing claims, and the closing of the strait adds another layer of complexity to the ongoing diplomatic efforts.
