A local news channel, Jamaran, reported that the attack failed to cause any structural damage to the steel mill since the factory happened to be non-operational at the time due to an electricity outage.

The company did not blame any specific group for the assault, which constitutes just the latest example of an attack targeting the country's services in recent weeks. Iran has previously accused the United States and Israel of cyberattacks that have targeted and crippled the country's infrastructure.

Khuzestan Steel Company, based in Ahvaz in southwestern Iran, has a monopoly on steel production in Iran along with two other major state-owned firms. Founded before Iran's 1979 Islamic Revolution, the company for decades afterwards had some production lines supplied by German, Italian and Japanese companies.
