Uttar Pradesh Chief Minister Yogi Adityanath has ordered all schools up to Class 12 to remain closed until January 5 due to an intensifying cold wave and dense fog. The directive applies to all educational boards, including CBSE and ICSE. Officials have been instructed to ensure adequate arrangements for blankets, bonfires, and functional night shelters for vulnerable populations, with a strict warning against negligence. The severe weather has also disrupted transportation services across the state.
