Due to a lack of evidence, it is not possible to objectively verify if Israel was behind the attack at the Iranian nuclear site.
Meanwhile, before the Natanz fire announcement, a BBC's Persian journalist said that he received an email from a group identifying itself as the 'Cheetahs of the Homeland' claiming responsibility for the attack. The BBC did not immediately verify the claim.
Israeli Defence Minister Benny Gantz reacting to the allegation indirectly said that Israel is not associated with the incident which occurred at the nuclear site in Iran.
However, there is no confirmation by Iran on how the incident took place as the matter is still under investigation.
