US-Iran Talks in Switzerland End Amid Tensions as Trump Threatens Strikes Over Strait of Hormuz ClosurePicrz.com Exclusive – Negotiators from the United States and Iran wrapped a full day of talks in Switzerland on Sunday, working to hammer out the details of an agreement aimed at ending the ongoing war. The discussions, however, were briefly strained after US President Donald Trump issued a direct threat of further military strikes against Iran should it move to close the Strait of Hormuz.According to sources familiar with the matter, the Swiss-hosted talks represent the highest-level diplomatic engagement between the two nations in recent months. Both sides sought to carve a path toward de-escalation, but Trump's sharp warning cast a shadow over the negotiations. He specifically named the Strait of Hormuz — the vital global energy transit chokepoint — and made clear that Washington would not tolerate any disruption to navigational freedom.The threat comes as maritime activity in the strait is already showing alarming signs of decline. Data from maritime intelligence firm Windward indicates a sharp drop in vessel transits, with multiple ships switching off their Automatic Identification Systems (AIS) to operate as "dark vessels." Iranian-linked and sanctioned ships have also been increasingly active in the area, pushing the strait closer to a blockade-like baseline than a normally functioning waterway. Trump's latest remarks are expected to further heighten regional tensions and shipping risks.No official details on the outcome of the talks have yet been released. Analysts suggest that the status of the Strait of Hormuz remains one of the central sticking points between Washington and Tehran.
