An International Atomic Energy Agency report declared Iran was not in compliance with its nuclear non-proliferation obligations shortly before Israel’s massive preemptive strike against the country.

The confidential May 31 report sent to the 35-nation IAEA Board of Governors claimed Iran was found to be conducting secretive nuclear activity in violation of previous agreements. On Thursday, the board passed a resolution holding Iran in non-compliance in a vote with 19 countries in favor, 11 abstentions, and three against — Russia, China, and Burkina Faso. The resolution was submitted by the United States, the United Kingdom, France, and Germany.

A joint statement from Iran’s foreign ministry and nuclear agency quickly denounced the resolution as “politically motivated,” saying the country would take “appropriate measures” in response to any actions taken against it.

The resolution came after the May report discovered secret nuclear activities within Iran.

“The Board of Governors… finds that Iran’s many failures to uphold its obligations since 2019 to provide the Agency with full and timely cooperation regarding undeclared nuclear material and activities at multiple undeclared locations in Iran… constitutes non-compliance with its obligations under its Safeguards Agreement with the Agency,” the report read, according to Reuters.

The IAEA’s “comprehensive” account of developments found three of four locations “were part of an undeclared structured nuclear programme carried out by Iran until the early 2000s and that some activities used undeclared nuclear material.”

It held that Iran failed to provide credible explanations as to why uranium traces were detected at undeclared sites.

U.S. intelligence has held that Iran was carrying out a secret nuclear weapons program parallel to the public program shown to the IAEA. IAEA Director General Rafael Grossi said the report’s findings were largely consistent with U.S. suspicions.

The resolution was the first time the IAEA had declared Iran non-compliant since September 2005. It came at a time of unprecedented tensions, when Israel repeatedly warned that Iran could make several nuclear bombs in weeks.

Despite the report, most countries condemned Israel’s Friday attack. Jordan, Iraq, Japan, Turkey, Indonesia, and the United Nations directly condemned the attacks, while France, Australia, NATO, and the U.K. called for restraint and de-escalation.

Israel hasn’t publicly said whether the report influenced its decision to strike Iran in the early hours of Friday.
