Argentina and Uruguay have been left without power after a "failure in the electrical interconnection system". Edusur, a major provider to the two nations, confirmed the outage in a tweet. The outage is affecting about 48 million people. Argentine website Infobae said Edusar confirmed "the blackout is at a country level and also affects Uruguay" and said nothing like this had ever happened. The outage is understood to have happened at 7am local time, about 12pm GMT. Uruguay's electricity service body UTE tweeted: "At 7.06 a defect in the Argentine network affected the interconnected system leaving the entire national territory without service, as did several provinces of the neighbouring country." People have reported blackouts in several regions. One twitter user shared an image of the darkened Mar del Plata.
