Smog in India's big smoke

Smog-filled landscapes like this one in Rajpath in New Delhi have been a common sight in the Indian capital for years, and the problem of air pollution shows no signs of abating.

Air quality in the city - which has been ranked the world's most polluted capital - stood in the "very poor" category yesterday morning, and is expected to deteriorate even further tomorrow.
