A drone strike triggered a fire near a nuclear power station in the emirate of Abu Dhabi on Sunday, authorities said, reporting no injuries or impact on radiation levels. The UAE's defence ministry said the drone that targeted the facility was one of three that "entered the country from the western border direction". The projectile struck "an electrical generator outside the inner perimeter of the Barakah Nuclear Power Plant in the Al Dhafra area". "Investigations are ongoing to determine the source of the attacks, and updates will be disclosed upon completion of the investigations," the ministry added. UAE presidential adviser Anwar Gargash appeared to refer to Iran and its regional proxy groups in his condemnation of the attack.

He called the incident "a dark scene that violates all international laws and norms", accusing the perpetrators of a disregard for the lives of civilians in the UAE. Iranian-backed armed groups equipped with drones are based in Iraq, while Tehran's allies in Yemen -- the Houthi rebels – also possess combat-grade UAVs. The UAE "condemned in the strongest terms the unprovoked terrorist attack" and "will not tolerate any threat to its security and sovereignty under any circumstances", a foreign ministry statement said. "These attacks constitute a dangerous escalation, an unacceptable act of aggression and a direct threat to the country's security," it added. UAE foreign minister Sheikh Abdullah bin Zayed Al Nahyan held calls with his counterparts in Qatar, Jordan, Saudi Arabia, Kuwait, Morocco, Egypt and Bahrain after the attack, his office wrote on X. The ministers condemned the attack and reaffirmed the Gulf nation's "full and legitimate right to respond" to it, his office added. The Barakah Nuclear Power Plant began operations in 2020 and is 200 kilometres (120 miles) west of the UAE's capital Abu Dhabi, near the borders with Saudi Arabia and Qatar. It provides up to a quarter of the oil-rich country's electricity needs, the state-owned operator Emirates Nuclear Energy Company said in 2024. "No injuries were reported, and there was no impact on radiological safety levels," the Abu Dhabi Media Office said. "All precautionary measures have been taken, and further updates will be provided as they become available. "The Federal Authority for Nuclear Regulation (FANR) confirmed that the fire did not affect the safety of the power plant or the readiness of its essential systems, and that all units are operating as normal."
