Chile suffers an expansive electricity blackout that forced the evacuation of the Santiago metro, slowed traffic to a crawl and left stores in the dark, say authorities. The rare outage started at 3:16 pm (1816 GMT) and stretched all the way from Arica in the long, narrow South American country's north to Los Lagos in the south, according to the SENAPRED disaster response agency. The government ruled out an attack or sabotage as the reason for the power loss in the middle of the southern hemisphere summer, saying a system failure was more likely to blame. IMAGES
