Tehran announced it had again closed the Strait of Hormuz. Donald Trump repeated his threats to resume attacks on Iran, stating on social media that Iran must stop its backed groups in Lebanon from causing trouble and warning that if they do not, the US would escalate military action against Iran. Trump also reiterated a threat that the US would take over the Strait of Hormuz and possibly charge a toll of its own. According to Fortune.com, US Vice President JD Vance negotiated with Iranian officials in Buergenstock, Switzerland, with Qatar and Pakistan serving as mediators. The talks, which stretched into their second day according to Al-Monitor, were held under the terms of a memorandum of understanding reached last week to extend a ceasefire that halts conflict on all fronts for at least another 60 days. Iran wants to discuss Lebanon before addressing other issues, according to Fortune.com. Gdelt reported that US and Iranian sources provided separate accounts of the discussions, and Iran's semi-official Tasnim news agency cited an informed source saying that after Trump's comments became public, the Iranian delegation left the negotiation room.
