Indian capital starts restricting cars to clear air

Few vehicles are seen plying on the otherwise severely busy Mehrauli Badarpur road during rush hour in New Delhi, India, Friday, April 15, 2016. The New Delhi government has begun a second round of a two-week car restriction whereby private cars will be allowed on the streets on alternate days from Friday until April 30 based on even or odd license plate numbers, to reduce air pollution that has made the Indian capital the world's most polluted city.
