The deadly episode was reportedly caused by a short circuit. Hospital fires are not uncommon in India, which lags in fire preparedness and building safety.

After reaching a peak, Delhi’s AQI has remained in the ‘severe’ category for the fourth day in a row. Covered in a thick blanket of fog and pollution, the poor visibility has even caused many school to remain closed for the past few days.

In response to dangerously high pollution levels, the Delhi government has ordered the closure of all primary schools starting Friday, with classes shifting online until further notice. Chief Minister Atishi made the announcement on social media.

Air pollution in the Indian capital is more than 50 times what is considered safe by the World Health Organization.

GRAP stage 3 will come into force at 8am on Friday. The Delhi government announced that classes for primary schools will be shifted to online.
