Secretary of Iran's Supreme Council of Cyberspace, Abul-Hassan Firouzabadi, said on Tuesday that a cyberattack carried out by a foreign country targeted Iran's fuel distribution network to disrupt services. 

Firuzabadi confirmed that the cyberattack did not cause any software damage, and the problem will be resolved in a short time.

On Tuesday, most fuel stations in Iran stopped working due to a technical defect in the computer system for fuel distribution.

Iranians are used to an IT system that allows them to fill their tanks for free or at subsidized prices with a digital card issued by authorities. 

The National Fuel Distribution Company announced that about 50 percent of the stations have resumed work.

Earlier, the Iranian state television confirmed that a cyberattack caused widespread disruption to the country's fuel distribution network.

"Details of the attack and its source are under investigation," the TV added.
