A new International Atomic Energy Agency (IAEA) report estimates that Iran has increased its stock of 60% enriched uranium to 17.7 kilograms, an increase of approximately 8 kilograms since the last IAEA estimate in August. The confidential report further states that inspectors are still unable to verify Iran's stockpile due to limited access to its nuclear facilities. A separate report raised concerns about intrusive searches of Agency inspectors by Iranian security personnel at nuclear sites. IAEA Director General Rafael Grossi is expected to visit Tehran on November 22nd.
