Negotiations between the United States and Iran in Switzerland under a memorandum of understanding (MoU) remain ongoing, with reports indicating that both sides are expected to continue discussions through the night.

The US delegation is led by Vice President J.D. Vance and includes Jared Kushner and Steve Witkoff. Iran's negotiating team is headed by Parliament Speaker Mohammad Bagher Qalibaf and Foreign Minister Abbas Araghchi. Pakistan and Qatar are serving as mediators in the talks.

According to a senior US diplomat quoted by the Associated Press, Iranian negotiators remained engaged in the discussions despite reports suggesting otherwise. The official said a significant portion of the talks focused on clarifying Tehran's recent statements regarding the Strait of Hormuz.

Earlier reports indicated that technical discussions had encountered a temporary impasse, although back-channel diplomacy remained active.

CNN reported that diplomatic efforts have continued behind the scenes despite heightened tensions, including remarks made by US President Donald Trump on Sunday.

Trump warned Iran against any attempt to close the Strait of Hormuz, threatening severe consequences and suggesting that the United States could take control of the strategic waterway and impose transit fees if Tehran proceeded with such a move.

"You close it, and you won't have a country. You won't even make it back to your f***ng country," Trump told Fox News.

Qalibaf rejected Trump's warning, stating that Tehran would not be intimidated by threats from Washington and asserting that Iran's armed forces were prepared to respond if necessary.

On the eve of the talks, Tehran reiterated that its concerns over the Strait of Hormuz were linked to Israel's ongoing military campaign in Lebanon against Hezbollah. Iranian officials have maintained that the interim deal is meant to stop fighting on all fronts, including Lebanon.

Other key issues under discussion include the potential unfreezing of billions of dollars in Iranian assets and addressing concerns surrounding Tehran's nuclear program.

Speaking to reporters, Iranian officials said Sunday's discussions were largely focused on developments in Lebanon, although other issues were also raised.

During the negotiations, Vance reportedly conveyed Washington's willingness to "fundamentally transform" its relationship with Tehran and "turn a new leaf" in diplomatic engagement, signaling a potential opening for improved ties if progress can be achieved on the outstanding issues.
