Dubai: A drone attack caused a fire at a nuclear power plant in the United Arab Emirates, Abu Dhabi officials said on Sunday, at a time when progress in efforts to end the US-Israel war with Iran and restart shipping in the Gulf appears to have stalled.Emirati officials said they were investigating the source of the attack and that the UAE had the full right to respond to such “terrorist attacks”. The UAE has previously accused Iran of attacking its energy targets, which it has said escalated the conflict in the region.The Abu Dhabi media office said the drone hit an electrical generator outside the inner perimeter of the Barakah nuclear power plant. It said radiological protection levels remained unaffected and no one was injured.The International Atomic Energy Agency said emergency diesel generators were providing power to “Unit 3” of the plant, and called for “maximum military restraint” near any nuclear power plant, adding that it was monitoring the situation closely. Barakah is the Arab world’s first and only nuclear power station.The UAE Defense Ministry said two other drones had been “successfully” dealt with, and that the drones were launched from the “western border”. It was not described in detail. agenciesUAE calls for unprovoked terrorist attack on N-reactorA statement from the Ministry of Foreign Affairs said the UAE “condemns in the strongest terms the unprovoked terrorist attack” and “will not tolerate any threat to its security and sovereignty under any circumstances”. “These attacks are a dangerous escalation, an unacceptable act of aggression and a direct threat to the country’s security,” it said.During the war, which began with US and Israeli strikes against Iran on February 28, Iran has repeatedly targeted the United Arab Emirates and other Gulf countries that host US military bases, attacking sites that include civilian and energy infrastructure.The UAE hosts air defenses and personnel from Israel, which sparked a war with the US on February 28 by attacking Iran. Meanwhile, Iranian state television aired segments with news anchors holding rifles in an effort to prepare the public for war.The UAE Defense Ministry said three drones came across its western border with Saudi Arabia, with the other two being intercepted. It was being investigated who had launched them.The $20 billion Barakah Nuclear Power Plant was built by the UAE with help from South Korea and went online in 2020. It is the only nuclear power plant in the Arab world and can provide a quarter of the energy needs in the UAE. The UAE nuclear regulator said on Friday that the fire did not affect the safety of the plant and that “all units are operating normally.” The IAEA, the UN nuclear watchdog, said the attack caused a fire in an electrical generator and that a reactor was being powered by an emergency diesel generator.
