Iran has sent a new nuclear proposal to the United States through Qatar. Still, a senior Iranian official told Reuters on Thursday, November 5, that Washington must meet seven conditions before negotiations can resume.

The official, who spoke on condition of anonymity, said the US was reviewing the proposal but did not reveal its details. The move comes as mediators step up efforts to end the war between Iran and the US. Concerns remain that fighting could resume after the November midterm elections.

Iran has linked further diplomatic talks to its demands, while Washington insists that Iran's nuclear programme must be part of the initial negotiations.

Iran's top security official, Mohsen Rezaei, also outlined Tehran's position during a visit to Russia on Thursday. He said Iran had already presented seven demands to Washington and would not return to negotiations until the US fulfilled them.

"On the issue of diplomacy, we have announced seven conditions to the Americans. As long as they do not execute our seven conditions, we will neither open the Strait of Hormuz nor have negotiations," Rezaei said.

Iran's demands include the removal of US sanctions, the release of frozen Iranian assets and payment of war reparations. Tehran has also made reopening the Strait of Hormuz conditional on Washington meeting its demands.

The latest proposal comes amid renewed diplomatic efforts to end the conflict. Qatar has been facilitating communication between Washington and Tehran.

The war began on February 28, when the US and Israel launched attacks on Iran. Tehran retaliated with strikes on Israel and Gulf countries hosting American military bases.

The conflict also spread to Lebanon, where Israel clashed with Iran-backed Hezbollah. In Yemen, the Iran-aligned Houthis launched attacks on energy facilities, airports and other targets in Saudi Arabia.

US President Donald Trump has not ruled out resuming military operations against Iran after the midterm elections. Tehran has warned that it would expand its retaliation if hostilities restart.

Washington continues to insist that Iran's nuclear programme must feature in the initial negotiations, while Tehran wants its seven demands fulfilled before agreeing to further talks.
