US, Iran Fail to Reach Deal after Marathon Pakistan Talks

The United States and Iran have failed to reach an agreement following marathon negotiations in Islamabad, marking a setback in efforts to end the ongoing Middle East conflict.
After 21 hours of talks, JD Vance said Washington had presented its «final and best offer» but had not received the key assurance it sought from Tehran — a commitment to abandon nuclear weapons development.
«We leave here with a very simple proposal… We’ll see if the Iranians accept it,» Vance told reporters, adding that discussions would continue as the US gives Iran time to respond.
The high-level meeting, the most significant direct engagement between the two sides in decades, took place amid a temporary pause in joint U.S.-Israeli military operations to allow space for diplomacy.
Pakistan, which hosted the talks, urged both sides to maintain dialogue and uphold the fragile ceasefire. Foreign Minister Ishaq Dar said Islamabad would continue to facilitate negotiations.
Iranian officials, however, blamed the deadlock on what they described as «unreasonable demands» from Washington, while acknowledging that a breakthrough was unlikely in a single round of talks.
The conflict, which began in late February, has intensified regional tensions and disrupted global markets, particularly after Iran restricted access to the Strait of Hormuz — a vital route for global oil supplies.
Despite deep mistrust between the two sides, diplomatic efforts are expected to continue as international pressure mounts for a resolution.
