In the latest development, the National Capital wakes up witnessing thick smog. The Air Quality Index(AQI) remains in the Severe category. #WATCH | Delhi: A layer of smog envelops the National Capital as the air quality continues to remain in the ‘Severe’ category as per the CPCB.

Delhi's air quality remains severely polluted for the fifth consecutive day, prompting the government to implement stricter measures. The ban on older vehicles aims to combat the hazardous smog engulfing the city and protect public health.

Northern India encountered the recurring annual pre-winter event of air emergency where the Air Quality Index (AQI) readings of main pollutant PM 2.5 breached the 400-mark of “very poor” and landed the air of Delhi, Punjab and other northern cities into the “hazardous” category.

Airport dropped to 800 meters at 7:30 am, leading to 107 flights being delayed and 3 cancelled, according to Flightradar.

Air pollution choking New Delhi has ground outdoor work to a halt and disrupted air travel in the Indian capital.

After reaching a peak, Delhi’s AQI has remained in the ‘severe’ category for the fourth day in a row. Covered in a thick blanket of fog and pollution, the poor visibility has even caused many school to remain closed for the past few days.

The GRAP 3 curbs in Delhi include ban on demolition and construction activities, and entry of certain vehicles inside Delhi-NCR, among other curbs, to prevent further deterioration of air quality.
