Tehran does not intend to negotiate on any of the provisions of the nuclear deal, and this also applies to the time of its operation, the Iranian government statement, published in response to the US withdrawal from the agreement, says.

"None of the provisions of the Joint Comprehensive Plan of Action (JCPOA) and its time frame, which has was negotiated over 12 years, are to be discussed in any form," the statement published on the Iranian government website says.

The US and its allies cannot limit Iran’s right to self-defense; Tehran is not developing missiles as weapons of mass destruction, according to the government.

Such a step is an "open violation" of the principles of international law, including the right to defense, the government stated, citing Article 51 of the UN Charter.

"The US and its allies… cannot impose restrictions on Iran's legitimate defenses, including our missile defense, which has been developed to deliver conventional weapons, taking into account the bitter experience of the Imposed War [the Iran-Iraq war in 1980-1988]," the government said in a statement posted on its website.

Against the background of fears among some Western countries about Iran's "influence" in the Middle East, Tehran also described its presence in Iraq and Syria as legitimate, noting that its support for Baghdad and Damascus that had proven to be effective in combating extremism.
