The National Security and Foreign Policy Commission of Iran's Parliament on Tuesday approved a plan to stop Iran's "voluntary" implementation of the Additional Protocol to the Non-Proliferation Treaty (NPT), semi-official Fars news agency reported.

Under the Iranian 2015 nuclear deal, also known as the JCPOA, signed by Iran and the six world powers including the United States, the Additional Protocol allows UN inspectors from the IAEA to carry out more intrusive inspections of Iran's nuclear program.

"Stopping implementation of the Additional Protocol, which was approved at the meeting of the parliament's commission this afternoon (on Tuesday), can also affect the future of the Iranian nuclear deal," Sara Fallahi, a member of the National Security and Foreign Policy Commission of the Parliament, told Fars.

In a reaction to the recent approval of a resolution on Iran by the International Atomic Energy Agency (IAEA), the Iranian Parliament has urged the government to reconsider the implementation of the Additional Protocol.

The IAEA's 35-nation board of governors passed a resolution on Friday, calling on Iran to cooperate fully with it and let the agency access two locations inside the country.

The board "calls on Iran to fully cooperate with the agency and satisfy the agency's requests without any further delay, including by providing prompt access to the locations specified by the agency," according to the text of the resolution submitted by France, Germany and Britain and adopted by a vote of 25 to two with seven abstentions, the IAEA said on its website.

By Tuesday, vote of the Parliament's commission to the withdrawal of Iran from implementation of the Additional Protocol, the Iranian Parliament gets one step closer to the final approval of the plan, which if ratified will oblige the government of President Hassan Rouhani to drop the commitments concerning the protocol.

Iran's parliament: IAEA resolution "politicized"

Earlier on Tuesday, the National Security and Foreign Policy Commission of Iran's Parliament condemned in a statement the recent resolution on Iran by the IAEA as "politicized and unprofessional."

"Over the past years, Iran has been more cooperative with the IAEA than other member states," said the Iranian parliament's statement.

However, "the IAEA adopted the anti-Iran resolution under the political and unprofessional pressures of the United States and its allies," it said.

The statement noted that the IAEA has adopted the resolution based on the allegations by the Israeli intelligence service.

"It is for the world to know if Iran gives positive response to the IAEA demand, which is based on the alleged intelligence, to access (the locations inside Iran), it will help create a wrong attitude towards other states," it added.

Iran will not allow the international institutions to be used as instruments by the U.S. and its allies to threaten the country's sovereignty, the statement stressed.

Iran's permanent representative to international organizations in Vienna, Kazem Gharibabadi, on Friday slammed the IAEA for adopting a resolution against Tehran, saying that "adoption of this resolution will neither encourage Iran to grant access to the Agency based on fabricated and unfounded allegations nor will it force Iran to come down from its principal positions."

"Iran will take appropriate action in response, the repercussions of which would be upon the sponsors of this resolution," said Gharibabadi.

After the U.S. withdrawal from the JCPOA in May 2018, Iran began to gradually reduce its commitments under the pact to retaliate Washington's departure and to respond to Europeans' "failure to honor their commitments."

On January 5, Iran took a fifth and last step in reducing its commitments and said it would no longer observe any operational limitations on its nuclear program concerning the capacity and level of uranium enrichment, as well as the volume of stockpiled uranium or research and development.
