Iran has successfully tested a new ballistic missile that can carry multiple warheads with explosives and can travel up to 2,000km, according to state media.
"Iran just test-fired a Ballistic Missile capable of reaching Israel", he said.
The state-run IRNA news agency quoted chief of the Guard's airspace division, General Amir Ali Hajizadeh, as saying that the ballistic missile "can carry several warheads for various uses".
The report said the missile was launched late Friday, without providing further details.
The Khorramshahr missile was first displayed at a military parade on Friday, where President Hassan Rouhani said Iran would strengthen its missile capabilities without seeking any country's permission.
Trump has repeatedly vowed to pull US backing from the deal; he has also called for including Iran's missile program.
The deal between Tehran and the six world powers, including the U.S., he said, allowed Iran to develop conventional weapons and also retained its ability to become a nuclear power.
If he says the country has violated the agreement, Congress will have 60 days to decide if the USA should re-impose the economic sanctions the deal lifted.
But Trump has been a staunch critic of the deal, claiming it makes the USA look weak on the worldwide stage.
In addition to carrying out missile tests, Iran has also launched a space satellite and fired missiles at Islamic State targets in eastern Syria in recent months.
That makes them only medium-range but still sufficient to reach Israel or United States bases in the Gulf.
President Hassan Rouhani made the statements at a military parade in Tehran in direct defiance of USA demands.
The ramifications of Donald Trump's very direct speech to the United Nations have continued to heighten tensions around the world.
But Washington says they breach the spirit of the agreement as they have the potential to carry a nuclear warhead and has imposed new sanctions over Tehran's continuing launches and tests.
Iran has insisted the missiles are not created to carry nuclear weapons and is not in violation of the resolution. This rocket has recently been presented at a military parade in Tehran.
Mr Trump included Iran among a "small group of rogue regimes", and said its government was bent on "death and destruction", adding that a nuclear agreement was an "embarrassment" to the US.
