An Israeli military spokesperson said on Thursday the military had struck nuclear sites in Bushehr, Isfahan, and Natanz, and continued to target additional facilities.
Bushehr is Iran's only operating nuclear power plant, which sits on the Gulf coast, and uses Russian fuel that Russia then takes back when it is spent to reduce proliferation risk.
The Russian embassy in Iran said in a statement earlier on Thursday that Bushehr was operating normally and that it did not see any security threats.
