On Sunday, an unclaimed drone struck an electrical generator near the Arab world's only nuclear power plant in Barakah in the emirate of Abu Dhabi, triggering a fire but causing no injuries or radiation leak. Two other drones had been intercepted.

Barakah is near the Saudi border and Qatar and the strike raised fears of consequences across the Gulf.

"As part of the ongoing investigation into the blatant attack on the Barakah Nuclear Power Plant on May 17, 2026, technical tracking and monitoring confirmed that the three drones... all originated from Iraqi territory," the Emirati defence ministry said.

Authorities intercepted six drones that also came from Iraq and "attempted to target civilian and vital areas" in the past 48 hours, the ministry added.

Iraqi authorities had already condemned the attack on Barakah before Abu Dhabi announced where the drones came from.

Iran has attacked the UAE and other Gulf nations since the US and Israel launched strikes on the country on February 28, targeting US assets but also energy and civilian infrastructure.

Before the April 8 ceasefire came into place, Tehran-backed Iraqi groups intervened in support of Iran and struck US facilities in Iraq and the wider region, including Gulf countries.

Iran-backed groups in Iraq have not claimed any strikes since the truce came into place, though Gulf countries have reported attacks from Iraq.

But the nuclear site had been off limits until Sunday.

The Barakah Nuclear Power Plant is the country's largest source of electricity and produces around a quarter of national power.

The site had been in Iran's crosshairs. In March, Iranian media published a list of power plants as potential targets, including Barakah.

On Sunday, Saudi Arabia had reported intercepting drones that came from Iraq, while Baghdad said its defence systems had not detected any drones launched from its territory toward the kingdom.
