Argentina said it isn’t ruling out a cyberattack after what President Mauricio Macri called an “unprecedented” power blackout struck five South American countries on Sunday.

Macri said Argentina is investigating the incident, which began with an as yet unexplained fault in its power grid that led to outages in Argentina, Uruguay, Brazil, Chile and Paraguay.
