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.

Unprecedented air pollution levels in Pakistan's second-largest city of Lahore prompted authorities to take emergency measures on Sunday, including issuing work-from-home mandates and closing primary schools.
