Delhi smog crisis: 10 flights cancelled; air quality remains ‘very poor’ at 350

Delhi’s air quality remains hazardous due to dense smog. Authorities have tightened pollution curbs, including restricting petrol sales for vehicles without PUC certificates and banning older vehicles. Air traffic is disrupted by fog and poor visibility. Commuters face anxiety over new vehicle restrictions. While some relief is expected from wind, pollution levels are likely to stay high.
