IAEA Chief Condemns Drone Attack on UAE Nuclear Plant, Hails Safety Response

Rafael Grossi, the director-general of the International Atomic Energy Agency (IAEA), concluded a closely watched visit to the United Arab Emirates on Tuesday with a forceful condemnation of the drone attack that struck the perimeter of the Barakah Nuclear Energy Plant last month, and with praise for what he called the “very professional” reaction of Emirati authorities. The visit, which included a tour of the facility and high-level talks in Abu Dhabi, marked the most direct international response yet to the 17 May assault, which Emirati officials say was launched by Iran-backed militants from Iraqi territory.

Grossi inspected the site where one of three explosive-laden drones evaded air defences and hit an electric generator outside Barakah’s inner security fence, near its third reactor. The impact triggered an immediate loss of external power, forcing an automatic shutdown of the unit. No radioactive release or casualties occurred, a result the IAEA chief described as a “trial by fire” that validated the plant’s robust design and the rapid action of its operators. Speaking near the plant, Grossi declared that attacks on peaceful nuclear installations were “completely unacceptable” under international humanitarian law and that the IAEA was offering technical support to reinforce the facility’s protections.

The episode cast a sharp light on the UAE’s rapidly expanding civil nuclear sector. Barakah, the Arab world’s first commercial nuclear power station, has since September 2024 been running all four of its reactors, supplying roughly a quarter of the nation’s electricity and accounting for three-quarters of its clean power. With a per-capita clean electricity output that now leads the world, the UAE has positioned the plant as central to its net-zero ambitions and energy security. During his tour, Grossi met Emirati engineers and observed advanced simulator training, commending a programme built, in his words, on the “highest standards of safety, transparency, and international cooperation.”

In a separate meeting, Sheikh Abdullah bin Zayed Al Nahyan, the UAE’s deputy prime minister and foreign minister, renewed Abu Dhabi’s condemnation of what it called “unprovoked terrorist attacks” by Iran, not only against Barakah but also against other civilian sites using missiles and drones. The two men discussed the broader threats to regional stability, international maritime navigation, and global energy supplies. Viewed from Western capitals, the incident reinforces long-standing fears that Iran’s asymmetric warfare capabilities could trigger a radiological catastrophe, while analysts in Tehran have remained largely silent on the strike, which Iraq-based proxies claimed.

The Barakah attack pushes the international community to confront an uncomfortable question: as more states in volatile regions adopt nuclear energy, how can their facilities be shielded from the sort of hybrid warfare now commonplace in the Middle East? Grossi’s visit signals the IAEA’s determination to extend its safety mandate to this new strategic landscape. For the UAE, the episode paradoxically strengthens its credentials: by withstanding a real-world worst-case scenario, Barakah has offered a global case study in resilience. Yet the thin margin between a close call and a catastrophe leaves no room for complacency.
