Power beginning to return in Venezuela after nationwide blackout

CARACAS/BARQUISIMETO, Venezuela — Power had returned to some parts of Venezuela on Friday evening after capital Caracas and much of the rest of the country were plunged into a blackout that the government blamed on sabotage by the opposition, without providing evidence. President Nicolas Maduro, who is locked in a dispute with the opposition over the outcome of a July 28 presidential election, has often held his political rivals responsible for what he says are "attacks" on the power grid, accusations the opposition has always denied.
