Delhi continues to choke as AQI remains ‘very poor’

Schools in Delhi and surrounding areas have moved classes online and construction has been banned as the Indian capital grapples with hazardous air quality.

On Monday morning, a toxic haze engulfed the city, affecting visibility and delaying flights and trains.

The city's air quality index (AQI) - which measures PM2.5, fine particulate matter that can clog lungs, and other pollutants - was more than 30 times the limit recommended by the World Health Organization. Exposure to this level of pollution can cause serious health problems, especially in children and elderly people.

Toxic air is a recurring problem in Delhi and its suburbs, especially during winters.
