VIENNA: Last month’s drone attack on the UAE’s Barakah nuclear plant was a “serious compromise of nuclear safety, the head of the International Atomic Energy Agency (IAEA) said Friday, adding any such attack “is unacceptable, a no-go, taboo.”

The UAE blamed pro-Iran militants in Iraq for the incident, which followed weeks of attacks by Iranian drones and missiles during the Middle East war.

The May 17 attack hit an electricity facility at the plant, risking potentially shutting it down, and IAEA chief Rafael Grossi warned that “attacks on nuclear facilities devoted to peaceful purposes are unacceptable.”

“The strike caused a fire in an electrical generator located outside the inner site perimeter of the NPP (nuclear power plant), prompting the need for emergency generators to provide power,” Grossi told an IAEA board meeting in Vienna.

The meeting was held at the request of Egypt, Jordan, Morocco and Saudi Arabia.
