Iran Press/America: Argentine President Mauricio Macri has promised a full investigation.
According to a report by The Independent, the power cut crippled public transportation in Buenos Aires, Argentina’s capital and in other major cities.
It also cut off the water supply, closed shops and brought down phone and internet communications across the country.
One of Argentina's top energy companies, Edesur, said it had restored power to 290,000 people by Sunday morning but said complete restoration would take several hours due to the seriousness of the situation.
Edesur has 2.5 million customers, according to its website.
Several provinces in Argentina were forced to temporarily delay local elections due to the blackout.
The cause of the outage was still unclear as of late Sunday morning, but Argentina’s energy agency said in a statement it had begun an investigation.
