DUBAI:Â A fire at Iran's Natanz nuclear facility last month was the result of sabotage, the spokesman for Iran's Atomic Energy Organisation told state TV channel Al-Alam on Sunday.
"The explosion at Natanz nuclear facility was a result of sabotage operations, security authorities will reveal in due time the reason behind the blast," said Behrouz Kamalvandi.
Iran's top security body in July said that the cause of the fire had been determined but would be announced later.
Iranian officials said that the fire had caused significant damage that could slow the development of advanced uranium enrichment centrifuges.
The Natanz uranium-enrichment site, much of which is underground, is one of several Iranian facilities monitored by inspectors of the International Atomic Energy Agency (IAEA), the UNÂ nuclear watchdog.
Some Iranian officials have said the fire may have been the result of cyber sabotage, and have warned that Tehran would retaliate against any country carrying out such attacks.
An article by Iran's state news agency IRNA in July addressed what it called the possibility of sabotage by enemies such as Israel and the United States, although it stopped short of accusing either directly.
Israeli officials declined to comment on Sunday.
