MOSCOW, May 6./TASS/. Russian Foreign Ministry Spokeswoman Maria Zakharova highlighted on Sunday the role of Iran’s anti-terrorist activity in Syria.

"In the search for a political settlement and efficient anti-terrorist activity in Syria, Iran can play and does plan an indeed effective and important role in fight against terrorism," the diplomat said in an interview with Iran’s IRNA news agency.

The Islamic Republic News Agency quoted her as saying that Iran’s role in fight against terrorism was important not only for Syria, but for the whole region as well. The Russian diplomat also noted that an attitude to Iran, first of that of the US, "will bring neither peace nor tranquility in the region, will not make Europe more secure".

US statements about its possible withdrawal from the Joint Comprehensive Plan of Action (JCPOA) signed among world powers and Iran poses a threat to the legal foundations of the present-day world, Zakharova said in an interview with the IRNA.

'US authorities' claim to withdraw from the JCPOA unilaterally is a threat to the international laws and security,' Maria Zakharova said, adding that it will add nothing to international peace and security.

IRNA quoted the Russian diplomat as saying the JCPOA is an agreement confirmed by the UN Security Council, so it is irrevocable.

The deal on Iran’s nuclear program, known as the Joint Comprehensive Plan of Action, was reached between Iran and six international mediators (Russia, the UK, China, the US, France and Germany) on July 14, 2015. In January 2016, the parties to the deal announced the launch of its implementation. Under the deal, Iran undertook efforts to curb its nuclear activities and place them under the total control of the International Atomic Energy Agency (IAEA) in exchange for lifting the sanctions that were imposed previously by the United Nations Security Council, the European Union and the United States over its nuclear program.

US President Donald Trump has stated on numerous occasions that the Iran nuclear deal is flawed arguing that it did not prevent the creation of nuclear weapons by Iran but only postponed it. On January 12, 2018, he said Washington would withdraw from the agreement if it were not amended.

In late April, a US administration spokesman said the United States, France, Germany and Britain had achieved progress at negotiations on amendments to the agreement on Iran’s nuclear program, but a final solution had not been identified yet. Tehran has repeatedly stated that the deal is not negotiable.
