Iran says cyberattack closes gas stations across country

A cyberattack targeted gas stations Tuesday across Iran, shutting down a government system managing fuel subsidies and leaving angry motorists stranded in long lines at shuttered stations.

No group immediately claimed responsibility for the attack, though it bore similarities to another months earlier that seemed to directly challenge Iran's Supreme Leader Ayatollah Ali Khamenei as the country's economy buckles under American sanctions.

State television quoted an unnamed official in the country's National Security Council acknowledging the cyberattack, hours after it aired images of long lines of cars waiting to fill up in Tehran. An Associated Press journalist also saw lines of cars at a Tehran gas station, with the pumps off and the station closed.
