Iran's Atomic Energy Organization said a destructive blast at the country’s main nuclear facility in July was caused by sabotage.
Iranian officials previously said the cause of the incident had been determined, but they declined to release details due to security concerns.
The agency’s spokesman Behrouz Kamalvandi told state TV channel Al-Alam on August 23 that "the explosion at Natanz nuclear facility was a result of sabotage operations. Security authorities will reveal in due time the reason behind the blast."
Some reports have suggested that Israel or the United States could have been behind the blast as part of their efforts to stop Iran from reaching a nuclear weapon.
Kamalvandi did not reveal whether the sabotage was internal or external.
