Iran has formally responded to a United States proposal aimed at ending the ongoing conflict in the Gulf region, according to Iranian state media, as diplomatic efforts continue amid tensions around the Strait of Hormuz.

Iran’s state-run IRNA news agency reported that Tehran delivered its response through Pakistani mediators, with discussions currently focused on ending hostilities and restoring stability in the region.

The latest exchange follows weeks of negotiations between Washington and Tehran over a possible ceasefire and broader security agreement. Reports suggest the US proposal included measures linked to Iran’s nuclear programme, maritime security, and the reopening of shipping routes through the Strait of Hormuz — one of the world’s most important oil transit corridors.

Iranian officials have indicated they want negotiations to prioritise ending the war rather than extending temporary truces. Tehran has also reportedly called for sanctions relief, the lifting of naval restrictions, and guarantees against future military action.

US officials have not publicly detailed Iran’s latest response, although American media reports suggest major differences remain between the two sides, particularly over uranium enrichment and regional security arrangements.

The conflict has raised international concern because of its impact on global energy markets and shipping routes. Pacific nations, including Tonga, remain vulnerable to rising fuel and freight costs linked to instability in the Middle East.

Diplomatic mediation led by Pakistan is continuing, with both sides expected to pursue further talks in the coming weeks.
