The Pentagon spokesman said the United States was not involved in the airstrikes on Iran, Reuters reported.

Brigadier General Patrick Ryder said the US military was not involved in the attacks on Iran, but declined to comment further.

Several other US officials, whose names were not disclosed, also told Reuters that the United States had nothing to do with the drone attack on a military plant in the Iranian city of Isfahan.

But as Al Arabiya television reported, citing American sources, the US Air Force may have participated in the attack on the military factory in Isfahan.
