Iran dismisses US "threats" amidst rising tensions

Besides, Moscow regretted the imposition of new sanctions by the United States on Iran after the latter's missile test, Russian Deputy Foreign Minister Sergey Ryabkov said Monday.

Iran's recent missile test did not violate the Joint Comprehensive Plan of Action or the UN Security Council resolution urging the Islamic Republic to drop nuclear-capable missile activities, Ryabkov was quoted as saying by the RIA Novosti news agency.

He added that the existing mechanism ensuring the peaceful nature of Iran's nuclear program is implemented without "specific problems."

In the reports released here on Tuesday, Iran's Foreign Minister Mohammad Javad Zarif also dismissed the threats by the new US President Donald Trump to reconsider the 2015 agreement which put an end to the disputes over Iran's nuclear issue.

Zarif said that the Iranian nuclear deal, known as JCPOA, is an international deal and its renegotiation is not acceptable, Tehran Times daily reported on Tuesday.

"I believe (US President Donald) Trump may try to renegotiate the nuclear deal," Zarif said, adding that "It's clear that neither Iran nor Europe will accept a re-examination of the deal. So, we have difficult days ahead."

Iran and six major world powers reached an agreement on the former's disputed nuclear program in July 2015, which was implemented in January last year.

Based on the agreement, Iran agreed to scale back its nuclear activities to a considerable degree in return for the lift of western and international sanctions.

Trump has criticized the deal, as a pact of "disaster" or "the worst deal ever negotiated" and has vowed to renegotiate the accord.

Going back on the deal is impossible as it is not a bilateral agreement between Iran and the United States, Zarif was quoted as saying.

Any review of the agreement, endorsed by the United Nations Security Council, will face resistance from the international community as well, he said.
