Two drones fell from the sky over the Abu Dhabi desert on Sunday afternoon. The third did not. It slipped past air defenses guarding the Barakah Nuclear Energy Plant, the first nuclear power station ever built in the Arab world, and struck an electrical generator just outside the inner perimeter. A fire started, but no one was hurt. The UAE's nuclear regulator said radiation levels never changed. For a few hours on May 17, the country faced something no Gulf nation had faced before: a successful drone strike on its nuclear plant. The three drones had crossed into UAE airspace from the west. Barakah sits about 225 kilometers west of Abu Dhabi city, near the Saudi border, in the Al Dhafra desert. Four South Korean reactors supply roughly a quarter of the country's electricity from this remote area. The damage was contained to the outer ring. The UAE said all units were operating normally and safety systems had not been affected. However, Rafael Mariano Grossi, Director General of the International Atomic Energy Agency, was not reassured. He warned that military activity threatening nuclear safety is unacceptable. The UAE Ministry of Foreign Affairs called the strike a terrorist attack and dangerous escalation. The strike came during what was supposed to be a ceasefire between the United States and Iran. Tehran had broken the truce and resumed strikes on the UAE in May. For the UAE, Barakah represents more than just infrastructure. It is a national project and a symbol of the country's bet on nuclear power. The drone did not damage a reactor, but it reached the plant, and that is enough to change everything.
