Delhi air: Choking smog draws protests ahead of Diwali - BBC News
Concerns about a rise in smog levels around Diwali have lead to protests over the city's air quality.
The air quality in the Indian capital is pretty bad at the best of times.

But it could get even worse during the festival of Diwali as people let off fireworks.

Some of those affected by the pollution are now calling on the government to act to avert what they say is a "public health emergency".
