MOSCOW, July 14. /TASS/. Iran and the six-powers agreement on the country's nuclear ambitions excludes military action against Tehran, Alexey Pushkov, head of the Foreign Affairs committee in the lower house of Russia's parliament, told a Moscow briefing on Tuesday.

"The Middle East region is the most unstable in the world," he said. "ISIS activities, the Arab Spring and United States' politics have caused civil conflicts and boosted terrorism from Tunisia to Pakistan." The regional nuclear weapons scenario "is extremely dangerous", he added.

"The agreement guarantees that Iran will use nuclear energy only for peaceful goals so other countries in the region [Saudi Arabia, Turkey, Egypt] do not have any arguments now for obtaining nuclear weapons," Pushkov said, adding that one of the key points of the Iran and six-powers agreement was removal of sanctions.

"We know that the USA considered the possibility of war against Iran," the lawmaker went on, noting that the agreement represented positive movement in international and Middle East politics.

Pushkov added that Israel opposed the accord: "Israeli authorities suppose that the agreement only postpones Iran's nuclear program but the treaty almost excludes war in the Middle East region," he said.

"Israel is unlikely to have technical opportunities for military operations against Tehran without the United States' help."

Iran and the six powers reached final agreement on Tuesday, a document containing 20 pages and five addendums.

Iranian president: "Tehran never wanted to possess nuclear weapons"

Iranian President Hassan Rouhani has called the Iran-P5+1 agreement, limiting Iran’s nuclear activity in return for the lifting of sanctions, an historic event.

"The agreement reached between Iran and six world powers today has become an historic event four our country, while the date of its signing will forever go down in history of the Islamic Republic", Rouhani told Iranian state television after the agreement was reached in Vienna earlier on Tuesday.

It was a big achievement that Iran and P5+1 could agree on very thorny issues, he said. The date of the signing was just a part of the path covered, he said, saying the date when the Joint Comprehensive Plan of Action started to be implemented would be a true test of readiness to comply with commitments fixed in the agreement.

"Chains in the form of sanctions that were a burden on the hands of Iran have fallen down," he said. "Those who maintained that Iran allegedly had plans to create nuclear weapons have practically got into a hobble. Iran has never had intentions to possess such weapons, it does not have them now and nor does it want to possess them [weapons] in the future," the president said.

"The agreement that the sides have arrived at today is the start of ‘a new day’ for Iran," he said.

"It will enable the country to freely develop the economy, create jobs, attract foreign investment, become more open to the world," President Rouhani said.

"Besides, Iran’s peaceful development will become a factor for the strengthening of security across the Middle East," he added.
