India reimposes stricter fog-related travel advisories as dense smog engulfs northern states

Several northern Indian states, including Delhi, Punjab, and Haryana, are once again experiencing dense winter smog and fog, prompting authorities to issue stricter travel advisories and safety guidelines over the past 24-48 hours. Road, rail, and air traffic movements have been disrupted, with numerous trains running late and some flights delayed due to poor visibility. Health officials have warned residents—especially children, the elderly, and those with respiratory conditions—to stay indoors and use protective masks when outside. Local governments have also announced temporary changes in school timings and increased monitoring of public transport to reduce accident risks as the pollution-related weather conditions continue.
