Delhi Implements Emergency Measures Amid Toxic Smog Crisis

Northern India and Pakistan are experiencing severe air pollution, with toxic smog causing flight delays and obscuring landmarks like the Taj Mahal. New Delhi's air quality index hit 'severe' levels, while Lahore was ranked the world's most polluted city. The smog crisis, exacerbated by crop burning, vehicle emissions, and industrial activity, has led to school closures and health warnings. Authorities in both countries are taking measures like spraying water to mitigate pollution, but the situation remains critical.
