India should follow China's example and clean up the air in its cities, which are among the world's worst for outdoor pollution, the World Health Organization said on Wednesday.
The WHO's database of more than 4,300 cities showed Indian cities such as New Delhi, Varanasi and Patna were among the most polluted, based on the amount of particulate matter under 2.5 micrograms found in every cubic meter of air.
Delhi was the world's sixth most polluted city, according to the WHO. On Wednesday, air quality in the capital stood at 143 micrograms, which is "unhealthy for sensitive groups".
