Israel should seek to overthrow the Iranian regime before the end of US President Donald Trump's administration, a senior official told Israeli public broadcaster KAN News on Monday.
Trump's second term as US president is due to end in January 2029.
Iran has been seeking to reproduce its stockpile of advanced missiles, and Israel is closely monitoring Tehran's efforts, a senior security source told KAN.
The New York Times, on Sunday, cited regional officials and analysts who view another outbreak of war between Israel and Iran as "only a matter of time."
Iran's new Pickaxe Mountain enrichment site, located approximately one kilometer south of the Natanz enrichment facility, is underway, and inspectors have not been permitted to access it, the NYT noted.
However, inspectors of the UN nuclear watchdog IAEA visited Iranian nuclear sites last week, Iran's foreign ministry spokesperson said on Monday, according to state media, a week after the IAEA urged Iran to "seriously improve" cooperation.
The IAEA has carried out about a dozen inspections in Iran since hostilities with Israel in June, but last week highlighted it had not been given access to nuclear facilities such as Fordow, Natanz, and Isfahan, which the United States bombed.
"As long as we are a member of the NPT (Treaty on the Non-Proliferation of Nuclear Weapons), we will abide by our commitments, and just last week, IAEA inspectors visited several nuclear facilities, including the Tehran Research Reactor," Esmaeil Baghaei said, without naming the facilities.
Iran's Pezeshkian says Tehran seeks peace, but will not bow to coercion
Iranian President Masoud Pezeshkian claimed on Friday that Iran seeks peace, but will not be coerced into abandoning its nuclear and missile programs, state media reported.
Trump said on Thursday that Iran had been asking if US sanctions against the country could be lifted.
"We are willing to hold talks under international frameworks, but not if they say you can't have a (nuclear) science, or the right to defend yourself (with missiles), or else we will bomb you," Pezeshkian said.
Last month, Pezeshkian warned that Iran may have no choice but to relocate its capital from Tehran to the south, possibly to a city in Hormozgan province, due to ongoing droughts.
Trump says Iran has been asking if US sanctions can be lifted
Trump said on Thursday that Iran has been asking if Washington's sanctions against the country can be lifted.
"Iran has been asking if the sanctions could be lifted. Iran has got very heavy US sanctions, and it makes it really hard for them to do what they'd like to be able to do. And I'm open to hearing that, and we'll see what happens, but I would be open to it," Trump told reporters late on Thursday at the White House.
Iran's mission to the United Nations in New York did not immediately respond to a request for comment.
