The air quality in Delhi is turning worse, Deputy Chief Minister Manish Sisodia said.
"Can't compromise with the health of children. All schools including private and government will remain closed till Sunday for all the classes," Sisodia said in a series of tweets.
The government had yesterday directed that primary schools would be closed today. It had also ordered suspension of outdoor activities for secondary classes.
The decision came after the Air Quality Index (AQI) touched 448 in a scale of 500, entering 'severe' category. Today, the AQI was worse at 484.
"The situation shall be reviewed on Sunday," it added.
