Delhi air pollution: National capital records worst AQI in a month

Delhi's air quality plummeted to 'severe' on Tuesday, hitting its worst level in nearly a month with an AQI of 433. A thick haze enveloped the city, prompting authorities to re-implement Stage-IV GRAP measures. Schools have shifted to a hybrid learning model for younger students, while online learning is encouraged for higher grades in affected NCR regions. Similar conditions are expected Wednesday before potential improvement to 'very poor' on Thursday.
