Speaking at a press conference, Baghaei said Tehran continued to exchange messages through intermediaries but did not provide further details.

Qatar and Pakistan, among other countries, have acted as mediators in efforts to end the war, which began with US and Israeli strikes on Iran on February 28.

Iran presented its proposal in mid-September after an interim ceasefire reached in June collapsed and intermittent strikes resumed. Tehran later confirmed that it had received a US response.

However, diplomatic efforts have stalled. Iran’s security chief said on Sunday that Washington’s response did not adequately address Tehran’s seven conditions for reopening the Strait of Hormuz and returning to negotiations.

A major point of disagreement is the timing of discussions on Iran’s nuclear programme. Washington wants the issue addressed from the outset, while Tehran says negotiations should initially focus on reopening the Strait of Hormuz and restoring security in the waterway.

Before the war, the strait carried about one-fifth of global oil and liquefied natural gas (LNG) trade, making it a critical route for international energy supplies.

Baghaei also addressed the escalating conflict between Saudi Arabia and Yemen’s Houthi movement, which is allied with Iran.

He reiterated Tehran’s willingness to help resolve the crisis through dialogue, saying the issue should have been addressed earlier through a United Nations roadmap.

Baghaei said Iran would support any agreement reached between the Yemenis and Saudi Arabia and called for the situation to be resolved through negotiations.
