Iran has reportedly threatened to build nuclear warheads and warned that it has the capability to turn New York into “hellish ruins” — amid stalled efforts to reinstate a nuclear deal between the county and world powers.

Two Telegram channels with ties to the Islamic Revolutionary Guard Corps posted a 2-minute video Saturday that vowed to quickly start building nuclear bombs if the “US or Zionist regime make any stupid mistakes,” according to Iran International, a London-based news outlet.

The video claims secret underground facilities in Fordow, near Qom, are close to working to turn the Islamic Republic into a nuclear power — and warned that its “peaceful nuclear program” could morph into a weaponized one with ease.

“The nuclear facilities of Fordow have been built deep under mountains of Iran and are protected against trench-busting bombs and even nuclear explosion,” the video reportedly states. “All infrastructures required for nuclear breakout have been prepared in it.”
