Major power failures affected millions of people across India earlier this week and reached some 2,000 miles from the borders with Myanmar to the east and Pakistan to the west. Some 670 million people, which is 10 percent of the world's population, were affected by the largest blackout in history on Tuesday. Even as power was restored today, arguments have arisen between state and federal officials over who is to blame. -- Lloyd Young (27 photos total)
