TEHRAN -- Iran's Parliament Speaker Mohammad-Bagher Ghalibaf said on Monday the legislature is moving to approve a plan to suspend Tehran's cooperation with the United Nations nuclear watchdog, as tensions intensify with the United States and Israel.

In a post on social media platform X, Ghalibaf accused the International Atomic Energy Agency (IAEA) of lacking "professional" conduct following recent attacks on Iranian nuclear sites.

"We in the Islamic Consultative Assembly are seeking to approve a plan to halt cooperation with the agency until we receive concrete guarantees of its professional behavior," Ghalibaf said.

The announcement comes after a series of strikes on Iran's nuclear and military infrastructure. On June 13, Israeli airstrikes targeted multiple sites inside Iran, including nuclear and military installations, killing several senior commanders, nuclear scientists, and civilians.

The United States followed on early Sunday with airstrikes on Iran's Fordow, Natanz, and Isfahan nuclear facilities.

The flare-up coincides with a recent resolution by the IAEA's Board of Governors, which, for the first time since 2005, declared Iran non-compliant with its nuclear obligations.

The move followed an IAEA report accusing Tehran of failing to fully explain the presence of nuclear material detected at three undeclared locations, while offering what the agency described as "less than satisfactory" cooperation.
