A massive power breakdown has hit India for a second day running, leaving more than half the country without power.
Power cuts are common in Indian cities because of a fundamental shortage of power and an ageing grid - the chaos caused by such cuts has led to protests and unrest on the streets in the past.
India's demand for electricity has soared in recent years as its economy has grown but its power infrastructure has been unable to meet the growing needs.
Correspondents say unless there is a huge investment in the power sector, the country will see many more power failures.
