The White House says it is “greatly concerned” regarding the International Atomic Energy Agency (IAEA) report detailing Iran's heightened production of highly enriched uranium.

In a statement on Tuesday, a spokesperson for the National Security Council underscored the alarming nature of Iran's nuclear escalation, saying "Iran’s nuclear escalation is all the more concerning at a time when Iran-backed proxies continue their dangerous and destabilizing activities in the region, including the recent deadly drone attack and other attempted attacks in Iraq and Syria and the Houthi attacks against commercial shipping vessels in the Red Sea,"

The IAEA report, disclosed by Reuters on Tuesday, highlighted Iran's reversal of a prior slowdown in its uranium enrichment program since mid-2023, indicating an increase in the production of highly enriched uranium. The report revealed that Iran is currently enriching uranium up to 60% at both its Pilot Fuel Enrichment Plant (PFEP) in the Natanz complex and its Fordow Fuel Enrichment Plant (FFEP) situated within a mountain.

The report conveyed to member states that "since the end of November 2023, the rate at which Iran has been producing uranium enriched up to 60% U-235 at these two facilities combined has increased to approximately 9 kg per month." According to the IAEA's definition, once uranium enriched to 60% reaches around 42 kg, the possibility of using it to create a nuclear bomb cannot be dismissed. Currently, Iran possesses sufficient uranium enriched to 60% to potentially manufacture three nuclear bombs if subjected to further enrichment.

Responding to the IAEA report on Wednesday, Mohammad Eslami, Iran's atomic energy chief, dismissed the findings, asserting, "There is nothing new." Eslami emphasized that Iran had not introduced any new elements and is conducting its activities in accordance with established rules, as reported by Iranian media.
