The power is out across Syria, state news agency SANA says. Government officials say they are working to restore service as soon as possible.
Syria's power grid went offline Thursday for unknown reasons, state media reported.
"The electricity network has been cut in all governorates," state news agency SANA said, reporting a source in the Ministry for Electricity. "Attempts to find out the cause of the outage have begun."
Blackouts have been frequent in the course of the five-year conflict but it is rare for the whole country to be affected at one time. Previous power failures were blamed on rebel attacks targeting the electricity network but so far Damascus has not blamed militants.
