Overnight threats by President Donald Trump against Iran amount to "psychological warfare", and Tehran will continue to resist its enemies, a senior commander of Iran's elite Revolutionary Guards was quoted as saying on Monday. "Be cautious!" Trump wrote.
On Tehran streets, residents took the exchange in stride.
The Iranians threatened to block the strait in 2008 and 2011, but backed down both times.
Gheibparvar's comments were reported by the semi-official ISNA news agency.
Leilaz says Trump and Kim got "closer" despite their previous warring words.
Other Iranian agencies carried similar reports.
Meanwhile, Trump's tweet was reverberating across the Mideast.
President Trump responded Sunday night to some belligerent rhetoric from Iran by taking to Twitter and "yelling" in all capital letters that Iran was risking annihilation.
Kamel Wazne says Iran can not trusts America after President Donald Trump pulled his country out of the nuclear deal with world powers and re-imposed sanctions on Tehran.
With the economic pressure, Trump said earlier this month that "at a certain point they're going to call me and say 'let's make a deal, ' and we'll make a deal".
The commander of Iran's powerful Revolutionary Guards has told Rouhani that he supports closing the strait if necessary, in response to the USA oil sanctions, which are due to kick in at the start of November.
Iran's economy and currency has tanked since Trump withdrew Washington from the 2015 Iranian nuclear agreement.
An Iranian official has dismissed the campaign, saying that the USA has tried in vain to undermine the government since the revolution in 1979.

Iran has denied the allegations and said its nuclear program is strictly for civilian purposes.
Pompeo said the U.S. government broadcasting agency was launching a 24/7 Farsi-language channel on TV, radio, digital and social media platforms. North's Foreign Ministry accused the United States of making "gangster-like" demands for its unilateral disarmament. "Regime leaders - especially those at the top of the IRGC and the Quds Force like Qasem Soleimani - must be made to feel painful consequences of their bad decision making", the top U.S. diplomat said, referring to Iran's special forces and Revolutionary Guards.
President Trump repeatedly criticized Iran and the nuclear deal during his first foreign trip as past year.
In May, the United States left a deal which curbed Iran's nuclear activities in return for the lifting of global sanctions.
Speaking at the Ronald Reagan National Library in Simi Valley, California, he added: "The level of corruption and wealth among regime leaders shows that Iran is run by something that resembles the mafia more than a government".
