IAEA chief Rafael Grossi expressed frustration at his agency’s attempt to monitor Iran’s nuclear program.
The UN nuclear watchdog has been unable to access footage of Iran’s sites and enrichment monitors since February.

“[We] are flying in a heavily clouded sky,” Mr. Grossi said. “[We] can continue in this way, but not for too long.”

Tehran continues to enrich uranium to near-weapons grade purity. The international community fears Iran is inching toward nuclear weapons.

“[Iranian authorities] have to give the guarantees of what is going on there,” Rossi said recently.
