Flights diverted in Delhi as toxic smog hits worst levels of 2019

Car fumes, industrial emissions and smoke from farms have contributed to pollution crisis

Pollution in Delhi has reached its worst levels so far this year, at almost 400 times the amount deemed healthy, causing planes to be diverted away from the city.

A week on from Diwali, the thick brown smog that shrouded the city after the festival has shown no sign of shifting. On Friday a public health emergency was declared and Delhi's chief minister Arvind Kejriwal said the city had turned into a "gas chamber".
