A fire broke out at the Nuclear Power Plant (NPP) in the city of Karaj, Iran, APA reports citing The Jerusalem Post.
Iran has not commented on the incident.
According to "Israel Radar" page on the X platform reports about fire in "nuclear power plant" are false as there's no such facility in Karaj. There's a nuclear research center there, as well as 2 standard power plants in the area (Montazere Ghaem and Amir Kabir).
