A drone strike targeted the UAE's Barakah Nuclear Power Plant Sunday, sparking a fire on the facility’s perimeter without causing injuries or any radiological leak, but underscoring fears of renewed conflict as the fragile Iran cease-fire remains under strain.
No one immediately claimed responsibility, and the UAE did not blame anyone. It has, however, accused Iran of launching multiple drone and missile attacks in recent days as tensions have risen over the Strait of Hormuz, a vital energy waterway that Iran still has in a chokehold.
The United States is blockading Iranian ports and diplomatic efforts aimed at a more durable peace have repeatedly faltered. The UAE has, meanwhile, hosted air defenses and personnel from Israel, which joined the U.S. in the Feb. 28 attack that sparked the war.
U.S. President Donald Trump has suggested hostilities could resume, and Iranian state television has repeatedly aired segments with anchors holding Kalashnikov-style rifles in an effort to prepare the public for war.
Fighting has also heated up between Israel and the Iran-backed Hezbollah armed group in Lebanon despite a nominal cease-fire there, further straining the wider truce.
The $20 billion Barakah nuclear power plant was built by the UAE with the help of South Korea and went online in 2020. It is the first and only nuclear power plant in the Arab world and can provide a quarter of all the energy needs in the UAE, a federation of seven sheikhdoms.
The UAE's nuclear regulator said the fire didn't affect plant safety. "All units are operating as normal," the organization wrote on X.
The UAE statement didn't blame any party for the attack. The Vienna-based International Atomic Energy Agency, the United Nations' nuclear watchdog, said the strike caused a fire in an electrical generator and that one reactor was being powered by emergency diesel generators.
IAEA Director-General Rafael Mariano Grossi expressed "grave concern" about the incident and said military activity that threatens nuclear safety is unacceptable, the agency said in a statement.
Sunday's strike marked the first time the four-reactor Barakah plant has been targeted in the war. It is near the border with Saudi Arabia, some 225 kilometers (140 miles) west of the UAE's capital city, Abu Dhabi.
Yemen's Iranian-backed Houthi rebels, whom the UAE have battled as part of a Saudi-led coalition, claimed to have targeted the plant while it was under construction in 2017, something denied at the time by Abu Dhabi.
The UAE signed a strict deal with the U.S. over the power plant, known as a "123 agreement," in which it agreed to give up domestic uranium enrichment and reprocessing of spent fuel to halt any proliferation fears. Its uranium comes from abroad.
That's very different from the nuclear program in Iran, which is at the heart of its long-running conflict with the United States and Israel.
Iran insists its program is for peaceful purposes, but it has enriched its own uranium close to weapons-grade levels and is widely suspected of having had a military component to its program until at least 2003. It has also often restricted the work of U.N. inspectors.
Israel is widely believed to be the only nuclear-armed country in the region, but has neither confirmed nor denied having atomic weapons. Iran struck near Israel's Dimona nuclear facility during the war.
Nuclear plants have increasingly been targeted in wars in recent years, including during Russia's full-scale invasion of Ukraine in 2022.
During the Iran war, Tehran repeatedly claimed its Bushehr nuclear power plant came under attack, though there was no direct damage to its Russian-run reactor or any radiological release.
There have been several instances of attacks around the Strait of Hormuz and Persian Gulf countries in recent weeks. Talks between Iran and the U.S. are at a standstill as the cease-fire threatens to collapse and tip the Middle East back into open warfare, prolonging the worldwide energy crisis sparked by the conflict.
Two people familiar with the situation, including an Israeli military officer, said Israel is coordinating with the U.S. about a possible resumption of attacks. The people spoke on condition of anonymity because they were discussing confidential military preparations.
Speaking to his Cabinet Sunday, Prime Minister Benjamin Netanyahu said, "our eyes are also open" when it comes to Iran.
He said he planned a chat with Trump later in the day to discuss the president's trip to China and "perhaps" other things. "We are prepared for any scenario," he said.
On Iranian state TV, presenters on at least two channels appeared armed during live programs.
In one program, Hossein Hosseini received basic firearms training from a masked member of the paramilitary Revolutionary Guard. After being shown how to prepare the weapon, Hosseini mimed firing a shot at the flag of the UAE.
On another channel, female presenter Mobina Nasiri said a weapon had been sent to her from a gathering in Tehran's Vanak Square so she could appear armed on camera. She said: "From this platform, I declare that I am ready to sacrifice my life for this country."
