US-Iran Talks Collapse After 21 Hours Amid Disputes Over Nuclear Programme, Strait of Hormuz

April 12, 2026

High-stakes negotiations between Iran and the United States ended without a breakthrough in Islamabad after nearly 21 hours of talks, as both sides failed to bridge deep divisions over Tehran’s nuclear programme and the strategic Strait of Hormuz.

The discussions, described as one of the most significant direct engagements between the two countries in recent years, were aimed at easing tensions and reaching terms that could stabilise the region, including reopening the vital oil transit corridor.

However, the talks broke down over key demands by Washington, particularly regarding Iran’s stockpile of enriched uranium and conditions tied to maritime access through the Strait of Hormuz.

Iranian officials, through state-linked media channels, blamed the failure on what they described as “excessive” and “unreasonable” demands by the United States. Tehran also accused Washington of attempting to secure at the negotiating table what it had failed to achieve through military pressure.

While both sides have yet to release detailed official transcripts of the talks, reports indicate that the U.S. position included curbs on Iran’s nuclear activities and proposals affecting security arrangements around the Strait of Hormuz a critical global shipping route through which a significant portion of the world’s oil supply passes.

Iran, however, rejected the proposals, insisting on its sovereign rights and maintaining that its nuclear programme remains within its strategic interests.

The failure to reach an agreement leaves the status of the Strait of Hormuz unresolved, raising concerns over global energy security and the potential for renewed escalation in the region.

Diplomatic observers say the outcome underscores the persistent mistrust between Tehran and Washington, with both sides maintaining hardline positions that continue to hinder meaningful compromise.

There was no immediate indication from either party on when, or whether, talks would resume.
