The Indian capital was shrouded in toxic smog on Wednesday as tens of thousands of people set off a multitude of firecrackers to celebrate the major Hindu festival of Diwali.
Pollution levels shot up to 681 in New Dehli – 20 times higher than what is considered safe by the World Health Organisation and could cause serious aggravation of heart or lung diseases.

He said: ’I have been driving an auto rickshaw since 1994, for 24 or 25 years, and it has been very difficult due to the high pollution. Sometimes when we clean our nose, it’s all black. When we spit or cough, that’s all black. This is a problem.’
Mohammad Shahid Raza, a young student, said people let off firecrackers until 1am on Thursday in a south Delhi neighbourhood where he lived.
He added: ‘It was very noisy, and on top of that the pollution level was so high, that when I went outside my house to buy some water, I could see dark clouds, and everything was completely dark. This is not good.’
Authorities this week tried to reduce dust by sprinkling water in many neighbourhoods and ordering builders to cover construction sites. Coal-based power stations in the Indian capital region have been shut down.
