U.S.-Iran Peace Talks in Islamabad Conclude Without Agreement

The United States and Iran concluded face-to-face peace talks in Islamabad, Pakistan, on April 12, 2026, without reaching an agreement, according to officials from both countries ^[1][2]. The discussions, which lasted approximately 21 hours, were led by U.S. Vice President J.D. Vance and Iran’s Parliament Speaker Mohammad Bagher Qalibaf ^[1][2].

The talks reportedly collapsed due to Iran’s refusal to commit to not developing a nuclear weapon, as stated by U.S. officials ^[1][2]. This issue was a significant sticking point in the negotiations, which aimed to address ongoing tensions between the two nations.

Pakistan’s Foreign Minister Ishaq Dar, who played a mediating role, urged both parties to maintain a fragile two-week ceasefire that had been agreed upon on April 7, 2026, to facilitate the negotiations ^[1][2].

While the primary reason for the breakdown was confirmed by multiple sources, Iran’s Foreign Ministry spokesman Esmaeil Baghaei mentioned a “gap between our opinions over two or three important issues,” though he did not specify what these issues were ^[3]. Additionally, reports from a single source suggested that Iran had proposed a 10-point plan, including control over the Strait of Hormuz and war reparations, but this was not confirmed by other outlets ^[1].
