Iranian authorities on Sunday reaffirmed their defiance toward U.S. demands following failed negotiations in Islamabad, Pakistan, aimed at ending the ongoing war. Parliamentary speaker Mohammad Bagher Ghalibaf said the U.S. delegation had failed to gain Iran’s trust, while President Donald Trump announced a naval blockade of the Strait of Hormuz and threatened further military action. Tehran’s leadership praised its delegation for refusing to eliminate nuclear enrichment or relinquish control over the strategic waterway, urging supporters to maintain their presence in the streets.

Judiciary chief Gholam-Hossein Mohseni-Ejei and several hardline lawmakers lauded the negotiating team for defending Iran’s sovereignty and “red lines.” State television blamed Washington’s “excessive demands” for the breakdown of talks, while the Islamic Revolutionary Guard Corps (IRGC) vowed to respond forcefully to any U.S. naval movements. The Iranian delegation of more than 85 members included senior officials from multiple factions, signaling an effort to project unity.

The talks concluded without progress, and both sides signaled readiness for further escalation. Russian President Vladimir Putin offered to continue diplomatic mediation, while Iran’s government extended online schooling amid economic strain and an ongoing internet shutdown.
