UPDATE: US-Iran talks in Pakistan end after 21 hours without agreement on Iran's nuclear program, leaving fragile ceasefire in jeopardy and war's future uncertain.
Vice President JD Vance left Pakistan Sunday morning after historic face-to-face talks with Iran ended without a peace deal. The negotiations, which lasted 21 hours, collapsed when Iran refused to commit to not developing a nuclear weapon, according to Vance. The breakdown leaves uncertainty over a fragile two-week ceasefire announced April 7 as the seven-week war entered a critical phase.
Vance said he remained in constant communication with President Trump throughout the negotiations but that Iran would not provide "an affirmative commitment that they will not seek a nuclear weapon, and they will not seek the tools that would enable them to quickly achieve a nuclear weapon." Iran's Foreign Ministry acknowledged a "gap between our opinions over two or three important issues" without specifying what they were. The ministry said negotiators reached mutual understanding on some topics, including the Strait of Hormuz, but did not mention nuclear weapons discussions.
Pakistan's Foreign Minister Ishaq Dar called on both countries to maintain their ceasefire commitment and said his country would continue facilitating dialogue. The talks marked the highest-level direct contact between the US and Iran since 2013, when President Obama called Iran's then-president to discuss the nuclear program. The war has killed thousands and disrupted global oil markets, with Iran's closure of the Strait of Hormuz affecting energy supplies worldwide.
