India power grid crisis deepens
A massive power breakdown has hit India for a second day running, leaving around 600 million people, half the population, without power.
Officials said the northern and eastern grids had both collapsed and many emergency services are running on back-up generators.
The BBC's Rajini Vaidyanathan said that one of the major concerns is the country's infrastructure, which has left many people unable to travel.
She added that many smaller parts of the country do not have access to back-up generators.
