Experts say car emissions are just one of several factors that have turned Delhi into what the city's Chief Minister Arvind Kejriwal has described as a "gas chamber".

Levels of dangerous particles in the air - known as PM2.5 - are at well over ten times safe limits.

Traffic restrictions have been imposed and schools and factories have been closed. Many people in the city are worried about how they will be affected.
