A massive blackout swept through all of Argentina and Uruguay on Sunday morning after an unexplained electrical failure in the Argentina network knocked out the interconnected system. Parts of Brazil and Paraguay have also reportedly been affected. Argentine media reports that the country's trains have been halted. "Never has anything like this happened before," Alejandra Martinez, a spokesperson for electricity company Edesur Argentina said. Argentina's energy secretary, Gustavo Lopetegui, said power was being restored in some parts of the country but that the process could take several hours. The combined population of Argentina and Uruguay is about 48 million people.
