Thirty-seven fights at Indira Gandhi International airport were diverted and hundreds were delayed because pollution caused low visibility.
Air quality is currently so poor that pollution indexes are classing it as hazardous and residents are wearing masks when outdoors.
India Today reported that the area declared a public health emergency last week.
“Pollution due to stubble burning is not in our hands though we are distributing masks to our Delhiites to reduce its ill-effects on the health of our people,” tweeted Arvind Kejriwal, chief minister of Delhi.
“However, let’s try to reduce pollution due to local sources as much as we can.”
