U.S. and Iranian negotiators have moved to Switzerland to finalize the details of an interim agreement, initiating a 60-day window to reach a permanent nuclear deal. The diplomatic push comes amid escalating maritime tensions, as Tehran claimed to have closed the Strait of Hormuz in response to U.S. policy regarding the war in Lebanon. However, U.S. Central Command (CENTCOM) has dismissed these claims, asserting that the waterway remains open and reporting that over 50 merchant ships transited the area on Saturday under U.S. monitoring. President Donald Trump has introduced a new mechanism of economic pressure, threatening to impose U.S.-administered tolls on shipping through the strait if a final agreement is not secured within the allotted two-month timeframe. Iranian officials have indicated that their cooperation remains conditional on the implementation of key commitments. Furthermore, reports indicate that Iran has informed Hezbollah that any easing of naval restrictions is tied to Israel accepting a comprehensive ceasefire in Lebanon, further intertwining regional conflicts with the ongoing nuclear negotiations.
