We reported earlier that an Israeli military official described it as a "mistake" to claim a strike on the Bushehr nuclear site in southern Iran - see our 12.24 post.
The official would only confirm Israel hit the Natanz, Isfahan and Khondab nuclear sites in the west.
Pressed further on Bushehr, the official said he couldn't confirm or deny Israel had struck the location, where Iran has a reactor.
An Iranian diplomat cited by Reuters news agency has commented on those remarks, describing Israeli claims as "psychological warfare", adding the site was not hit.
Bushehr is Iran's only operating nuclear power plant.
Sitting on the Gulf coast, it uses Russian fuel that Russia then retakes when it is spent to reduce proliferation risk.
Russian President Vladimir Putin said yesterday that Moscow had agreed with Israeli leaders that the safety of Russian workers at the site would be guaranteed.
The potential consequences of an attack on the plant have long been a concern in the Gulf states.
