The UAE’s foreign ministry called the strike an “unacceptable act of aggression” and said it had the right to respond to any hostilities.
It added that “the targeting of peaceful nuclear energy facilities is a flagrant violation of international law, the UN charter, and the principles of humanitarian law”.
The country’s defence ministry meanwhile said it would “firmly confront any attempts to undermine the country’s security”.
Officials have not said from where the drone was launched. The UAE has previously accused Iran of being behind attacks on its energy and economic infrastructure since war broke out in the region in February.
The Abu Dhabi Media Office said the fire “broke out in an electric generator” and confirmed precautionary measures had been taken at the plant, which is operating as normal.
The UN’s nuclear watchdog said it was monitoring the situation closely and that its director general Rafael Grossi expressed “grave concern” about the incident.
Grossi said “military activity that threatens nuclear safety is unacceptable”, according to a statement shared by the International Atomic Energy Agency on X, and called for “maximum military restraint”.
