Closure of Primary Schools in New Delhi: What's the Reason?

Delhi's Education Minister Atishi Marlena announced that primary schools in the Indian capital will remain closed until November 10 due to rising pollution levels. For classes from sixth to twelfth grade, she noted that "there is a possibility of continuing lessons online." The air quality index in New Delhi reached 471 on Sunday, placing the city in the "hazardous" category. It was followed by Lahore in Pakistan with a "very unhealthy" level of 261. The air quality index ranges from 0 to 50, which is considered good, while a range of 400 to 500 negatively impacts healthy individuals and is dangerous for those with existing health conditions. New Delhi ranks as the most polluted city in the world, according to Swiss group IQAir's global air quality rankings.
