A massive blackout left tens of millions of people without electricity in Argentina, Uruguay and Paraguay on Sunday in what the Argentine president called an “unprecedented” failure in the countries’ power grid.
Authorities were working frantically to restore power, and by the evening electricity had returned to 98 percent of Argentina, according to state news agency Telam. Power also had been restored to most of Uruguay’s 3 million people as well as to people in neighboring Paraguay.
On Sunday morning, Argentine voters were forced to cast ballots by the light of cellphones in gubernatorial elections. Public transportation was halted, shops closed and patients dependent on home medical equipment were urged to go to hospitals with generators.
