Primary schools in Lahore will remain closed for a week because of the pollution, according to a government notification.

Unprecedented air pollution in the Pakistani city of Lahore has forced authorities to close all primary schools for a week. From Monday, 50% of office workers will also work from home, as part of a "green lockdown" plan. Other measures include bans on engine-powered rickshaws and vendors that barbecue without filters.

The smog crisis in Lahore, similar to the situation in India's capital Delhi, tends to worsen during cooler months due to temperature inversion trapping pollution closer to the ground.
