The lawmaker also noted that US President Barack Obama�s statements on the deal on Iran�s nuclear program should be treated with caution.

MOSCOW, April 3. /TASS/. Some countries, including Israel and Saudi Arabia, may try to disrupt the agreements reached on Iran�s nuclear program in Switzerland�s Lausanne, Russian State Duma Committee on International Affairs head Alexey Pushkov said on Friday.

On April 2, Iran and P5+1 group (Russia, US, UK, China, France and Germany) reached a breakthrough agreement on restricting Tehran�s nuclear program in exchange for gradual lifting of sanctions. The deadline for coordinating the final agreement is June 30.

The situation "does not benefit those countries in the Middle East that want to continue their uncompromising fight against Iran and its influence," Pushkov said. It cannot be ruled out that influential political players - among them are Israel, Saudi Arabia and several other countries - may try to disrupt the agreement and bring the situation back to the high level of tensions which dominated around the Iranian nuclear program over the last years," the lawmaker noted.

The lawmaker noted that US President Barack Obama�s statements on the deal on Iran�s nuclear program should be treated with caution, taking into account a recent demarche by several Republican senators.

"If the opposition [Republicans] threaten to break the international agreement only because it was signed by a Democrat president, than, in my view, this signifies the fact that such statements by the current president [Obama] and signed agreements should be treated very cautiously," Pushkov said.

The Republicans "are trying to undermine confidence in Obama, and this in turn undermines trust to US policy in general," the lawmaker stressed.

EU foreign policy chief Federica Mogherini said a "decisive step" has been achieved. "This is a crucial decision laying the agreed basis for the final text of joint comprehensive plan of action. We can now start drafting the text and annexes," Mogherini said. Iranian Foreign Minister Javad Zarif called the deal a "win-win outcome."

Moscow hailed the agreement, saying that "the agreement is a unique, most complex document which is yet to be elaborated in detail."
