Delhi schools to conduct online classes for students up to Class 5 as air quality worsens

Delhi's AQI hit 437, prompting the Singapore High Commission to advise its nationals to stay indoors, wear masks, and follow local guidelines. Stage 4 of the Graded Response Action Plan was triggered, restricting construction and industrial activities, and encouraging hybrid work for schools and offices. Severe smog disrupted daily life and air travel, with over 400 flights delayed and authorities urging residents to limit outdoor activities and wear masks.
