A similar missile was tested in late January and blew up 600 miles after launch.
He cautioned that Iran's claim that the new missile could carry multiple warheads "needs to be taken with a grain of salt", adding that the it "may mean nothing more than multiple cluster bombs", not the kind of ballistic missile payload - multiple independently targetable reentry vehicle, or MIRV - associated with nuclear missiles.
Iran said in its announcement Saturday that the Khorramshahr missile could carry several warheads.
The parade was one of many across Iran on the first day of the annual week-long commemoration of Iranian forces during the 1980s Iraq war.
The IRGC and the volunteer militia Basij forces participated in the parade. "We must not allow this to happen", said Liberman.
US President Donald Trump has threatened to bin the agreement over the issue, saying that Iran's missile program could give it the technical knowhow for a delivery system for a nuclear warhead when a sunset clause in the deal expires in 2025.
President Rouhani has vowed to strengthen Iran's ballistic missile programme, defying American warnings that Tehran was breaching its nuclear pact with the West. We will not seek anyone's permission to defend our land.
"We will not put up with threats and intimidation, we believe in negotiations and moderation", he continued, referring to US President Donald Trump's speech.
Trump is due to report to Congress on October 15 on whether Iran is still complying with the deal and whether it remains in United States interests to stick by it. Thousands of worshipers marched after Friday prayers in Tehran, chanting "Death to America" and "Death to Israel".
On Thursday, Iran's Supreme Leader Ayatollah Ali Khamenei, who has final say on all major policies in Iran, said Trump's "cheap, ugly, foolish and unreal" remarks before the U.N. General Assembly were a sign of desperation.
David Albright, a former UN nuclear inspector who authored the new report, said Iran's compliance also had improved because the United States is taking a tougher line on attempts to "violate the nuclear limits and exploit loopholes".
Press TV stated that the U.S. claims that Iran's missile tests and rocket launches violate UN Resolution 2231, which was adopted in July 2015 to endorse the 2015 nuclear agreement between Iran and the five permanent members of the UN Security Council plus Germany.
