The United States and several allies are pushing for a vote at the International Atomic Energy Agency (IAEA) board next week to report Iran to the UN Security Council for the first time in 20 years, diplomats say. The proposed resolution is intended to escalate the IAEA’s actions through the Security Council channel.

The effort is described by multiple outlets as following an earlier IAEA board decision on June 12 last year, when the board declared Iran in breach of its non-proliferation obligations for not fully cooperating with an investigation into uranium traces at undeclared sites. One outlet links the timing to Israel bombing Iranian nuclear sites the day after that June 12 decision, adding that inspectors have not returned to verify what remains, including enriched uranium levels reported to have reached up to 60% purity.

While the outlets largely converge on the push for an IAEA board resolution and its stated basis in the June 12 action, they differ slightly in emphasis—some focus mainly on the diplomatic push and the 20-year milestone, while others add details about the access dispute and the impact of the bombings on IAEA verification since then.
