RIO DE JANEIRO (AP) - Brazil's two largest cities have been hit by a massive blackout that has also affected other parts of Latin America's largest nation.
Media reports say problems at a huge hydroelectric dam are to blame for the electrial outages affecting large parts of Rio de Janeiro, Sao Paulo and other cities in several states.
The G1 Web site of Globo TV says Brazil lost 17,000 megawatts of power after an unspecified problem happened at the Itaipu dam that straddles the border of Brazil and Paraguay.
Officials did not immediately comment on Tuesday's outages. The blackouts came three days after CBS's "60 Minutes" news program reported several past Brazilian power outages were caused by hackers. Brazilian officials played down the report.
