New Delhi, Nov 18 (HBTV): In a significant ruling, the Supreme Court of India has ordered the closure of 10th and 12th grade classes across the Delhi- National Capital Region (NCR) due to the worsening air quality.

The Court emphasised the need for all educational institutions to switch to online classes as a precautionary measure against hazardous air pollution levels.

Earlier, the physical classes were discontinued for all students, except those in classes 10 and 12. According to the court's new order, now, all classes will be continued online for the sake of student's well-being.

Delhi's air quality worsened to the 'severe plus' category on Monday with the city recording an AQI of 484. The authority implemented pollution control measures, including a ban on truck entry and suspension of construction at public projects, which came into force in the morning. The dense toxic smog caused visibility to drop sharply in the morning.
