The fire reportedly broke out in an electrical generator outside the internal safety zone at the Barakah nuclear power plant, according to a statement on social media.
"No injuries have been reported and there has been no impact on radiation safety levels."
The fire did not affect the safety of the facility and "all units are operating as usual," the United Arab Emirates Nuclear Energy Authority wrote on X.
An active partner?
No one has claimed responsibility for the attack, and the United Arab Emirates is not pointing to any party as responsible.
The UN's atomic energy agency, the IAEA, says it is monitoring the situation closely and is in constant contact with local authorities.
"Director General Rafael Grossi expresses deep concern about the incident and says that military activity that threatens nuclear safety is unacceptable," the IAEA writes on X.
The Barakah nuclear power plant, which came into operation in 2020, is the first and only nuclear power plant on the Arabian Peninsula. This is the first time the facility, which has four reactors, has been attacked during the war.
This comes after Iranian Foreign Minister Abbas Araghchi earlier this week accused the United Arab Emirates of being an "active partner" in the US and Israel's war against Iran.
The move came after reports that Israeli Prime Minister Benjamin Netanyahu secretly visited the UAE during the war, that Israel had sent anti-missile systems and personnel to the United Arab Emirates, and newspaper reports that the UAE had secretly attacked Iran during the war.
Multiple attacks
In recent weeks, there have been several attacks around the Strait of Hormuz and in the Persian Gulf. A fragile ceasefire exists between the United States and Iran, but talks have stalled and threaten to return the Middle East to open warfare - which would prolong the global energy crisis triggered by the conflict.
Iranian state media reported on Sunday that the United States had not made any concessions when responding to Tehran's latest proposal for peace talks, according to AFP.
