Iranian parliamentarians are preparing a bill that could push Tehran toward exiting the nuclear Non-Proliferation Treaty, the country’s foreign ministry said on Monday, while reiterating Tehran’s official stance against developing nuclear weapons.

“In light of recent developments, we will take an appropriate decision. Government has to enforce parliament bills but such a proposal is just being prepared and we will coordinate in the later stages with parliament,” ministry spokesperson Esmaeil Baghaei said, when asked at a press conference about Tehran potentially leaving the NPT.

The NPT, which Iran ratified in 1970, guarantees countries the right to pursue civilian nuclear power in return for requiring them to forgo atomic weapons and cooperate with the UN nuclear watchdog, the International Atomic Energy Agency.

Israel began attacking nuclear sites and other military and energy targets in Iran early Friday, saying Tehran was approaching “the point of no return” and was on the verge of building nuclear weapons.

Iran insists that its nuclear program is peaceful, although it has been enriching uranium to levels that have no peaceful application, has obstructed international inspectors from checking its nuclear facilities, and has greatly expanded its ballistic missile capabilities.

Iranian President Masoud Pezeshkian nevertheless insisted on Monday that nuclear weapons were against a religious edict by Supreme Leader Ayatollah Ali Khamenei.

The IAEA declared last week that Tehran was in violation of its NPT obligations.

Iran’s state media said that no decision on quitting the NPT had yet been made by parliament, while a parliamentarian said that the proposal was at the initial stages of the legal process.

However, Iran’s mission to the UN in Vienna said on Monday that expectations that Iran continue its voluntary commitments to the nuclear nonproliferation treaty (NPT) are “unjustified,” when the country’s rights to pursue civilian nuclear power under the treaty are not respected, and its nuclear facilities are targeted by a non-member.

Baghaei, the foreign ministry spokesman, said that developments such as Israel’s attack “naturally affect the strategic decisions of the state,” noting that Israel’s attack had followed the IAEA resolution, which he suggested was to blame.

“Those voting for the resolution prepared the ground for the attack,” he said.

Israel, which never joined the NPT, is widely assumed by regional governments to possess nuclear weapons, although it does not confirm or deny this.

“The Zionist regime is the only possessor of weapons of mass destruction in the region,” Baghaei said.
