Iranian President Masoud Pezeshkian is calling on the International Atomic Energy Agency to drop its “double standards” if it hopes to normalize relations with his government. According to the Islamic Republic News Agency, the Iranian leader accused the IAEA of “biased and unprofessional conduct” on Thursday, but noted that Iran was “committed to constructive engagement, regional peace, and global stability.” Pezeshkian’s comments come a week after he signed a bill suspending cooperation between Iran and the nuclear watchdog, prompting the IAEA to withdraw its inspectors from the Islamic Republic. The Iranian Majlis passed the legislation in late June by a vote of 221-0-1.

“The continuation of Iran’s cooperation with the agency (IAEA) depends of [sic] the latter correcting its double standards regarding the nuclear file,” Pezeshkian told European Council President António Costa. “Any repeated aggression (against Iran) will be met with a more decisive and regrettable response.” He added that “failure to observe the principle of impartiality in reporting is one of the examples that casts doubt on the status and credibility of the IAEA.”

Tehran partly blames the IAEA for the US-Israeli bombardment of its nuclear facilities last month. It disputes the agency’s June 11 report, which alleged a lack of cooperation on Iran’s part and declared the Islamic Republic in violation of its non-proliferation duties. Iranian officials say that the IAEA resolution provided the US and Israel with a pretext for their attacks. They also claim that members of IAEA Director General Rafael Grossi’s staff spied on Iranian nuclear facilities and furnished intelligence to the Mossad.

The New York Times reported on Thursday that Israel believes some of Iran’s enriched uranium stockpiles survived the June bombings. A senior Israeli official also told the newspaper that Israel began preparing for military action against Iran late last year, soon after the assassination of Hezbollah Secretary-General Hassan Nasrallah in September. In June, US intelligence agencies reaffirmed their March assessment that Iran has yet to pursue a nuclear weapons program.
