Iranian President Masoud Pezeshkian claimed that Israel tried to assassinate him in an interview with conservative US podcaster Tucker Carlson, released on Monday.
"They did try, yes," he told Carlson on Saturday. "They acted accordingly, but they failed."
Israel did not immediately respond to the allegation. A senior IDF official said last month that Israel killed more than 30 senior security officials and 11 senior nuclear scientists in its attack on Iran's nuclear sites.
Pezeshkian blamed Israel for the collapse of talks that were in place when Israel began its strikes on Iran on June 13, starting a 12-day air war with Israel in which top Iranian commanders and nuclear scientists were killed.
"How are we going to trust the United States again?" Pezeshkian said. "How can we know for sure that in the middle of the talks, the Israeli regime will not be given the permission again to attack us?"
Pezeshkian also said he believes Iran can resolve its differences with the United States through dialogue, but trust would be an issue after the strikes.
"I am of the belief that we could very much easily resolve our differences and conflicts with the United States through dialogue and talks," Pezeshkian said.
Pezeshkian urges Trump not to be drawn into war with Iran
The Iranian leader urged US President Donald Trump not to be drawn into war with Iran by Benjamin Netanyahu, who is visiting Washington on Monday for talks at the White House.
"The United States' president, Mr. Trump, he is capable enough to guide the region towards the peace and a brighter future and put Israel in its place. Or get into a pit, an endless pit, or a swamp," Pezeshkian said. "So it is up to the United States president to choose which path."
White House spokeswoman Karoline Leavitt said she was not sure if Trump had seen the Iranian president's comments, but agreed he was the right man to move the region towards peace.
Trump said he expected to discuss Iran and its nuclear ambitions with Netanyahu, praising the US strikes on Iranian nuclear sites as a tremendous success.
On Friday, he told reporters that he believed Tehran's nuclear program had been set back permanently, although Iran could restart efforts elsewhere.
Iran has always denied seeking a nuclear weapon.
