According to the Associated Press, Iran's civilian nuclear program says an "accident" has occurred in the country's Natanz nuclear facility's electrical distribution system.

According to reports, Behrouz Kamalvandi said on Sunday that there were no casualties or pollution as a result of the incident.

After an explosion destroyed Natanz's advanced centrifuge facility in July, the incident occurred. The incident was later labeled as sabotage by Iran.

According to the semiofficial Fars news agency, Kamalvandi said at the time, “This incident was, unfortunately, an act of sabotage, and the security organizations should thoroughly investigate the incident, and they must talk about it, and their investigations will continue.”

“As far as we know, they have recognized the perpetrators and are aware of their incentives and tactics, and they are fully aware of the situation,” he said.

Iran announced an "incident" at the Natanz complex on July 2 but said there were no injuries and that the incident failed to halt enrichment work at the plant.

A member of Iran's National Security Committee later claimed that the blast in Natanz was triggered by a "security breach," and a subsequent study claimed that Iran had ruled out drone or missile attacks as the cause of the blast.

The blast in Natanz came six days after a blast near a military complex in the Parchin region southeast of Tehran, which shook the Iranian capital. The explosion was blamed on "leaking gas tanks," according to authorities.
