Venezuela's Maduro: US Triggered Massive Blackout Associated Press CARACAS, Venezuela -- Venezuelan President Nicolas Maduro on Wednesday blamed the United States for a second widespread blackout this year that cast most of the South American nation in darkness amid an opposition campaign to overthrow him. Cuban officials, meanwhile, underscored that their support for Maduro is unwavering, saying U.S. attempts have failed to divide the communist island from the ideologically aligned Venezuelan leader. The most recent power outage hit Venezuela at rush hour Monday, leaving millions without basic services such as cellphone service, lights and running water while freezing Caracas' subway and snarling traffic. 'High-tech' attack Maduro said the U.S. launched a ``high-tech electromagnetic attack'' to undermine his rule, but he gave no details or evidence linking the power failure to the United States. In March,heblamed U.S. sabotage for a nationwide blackout lasting nearly a week, considered the nation's worst power failure in its history. Maduro's opponents blame the outages on corruption and inadequate maintenance under two decades of socialist rule launched by the late President Hugo Chavez. Venezuelan officials also say the U.S. twice within the last week has sent a spy plane into its airspace. In one case, a Venezuelan fighter jet intercepted it, which U.S. officials say put the plane's crew in danger and threatenedits mission conducted while flying in international airspace. .
