TEHRAN, Sept. 19 (Xinhua) -- A senior Iranian security official said Iran has not yet decided whether to withdraw from the Treaty on the Non-Proliferation of Nuclear Weapons (NPT), adding that any decision on the issue will depend on Washington's behavior.

In an interview with Qatar's Al Jazeera published on Saturday, Secretary of Iran's Supreme National Security Council Mohsen Rezaei said the country is still committed to a religious decree issued by its late Supreme Leader Ali Khamenei, which prohibits developing atomic weapons.

"However, we do not know what will happen in the future," he noted, stressing that it is in Washington's interest to accept Iran's conditions for ending the war, which include ending hostilities on all fronts, releasing frozen Iranian assets, and lifting the anti-Iran naval blockade.

He added that consultations with Qatari and Pakistani mediators are continuing, and Iran has informed them of its conditions for negotiations with the United States.

On Feb. 28, Israel and the United States launched joint attacks on Tehran and other Iranian cities. Iran responded with waves of missile and drone attacks targeting Israel and U.S. bases and assets in the region, and tightened its grip on the Strait of Hormuz.

On June 18, the United States and Iran signed a memorandum of understanding (MoU) on ending the war in the region on all fronts. Under the MoU, they were scheduled to hold negotiations within a period of 60 days, which ended on Aug. 17, to reach a final agreement, but the talks' fate remains unclear following a series of recent escalations between the two countries.
