A smog-choked province in eastern Pakistan has issued a rare plea for cross-border collaboration with India, as major cities in both countries endure severe air pollution that risks the health of millions.

Pakistan blames India for worsening smog in Lahore, urging serious action as air quality index hits record high.

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

As a result of the record high pollution, authorities in Lahore have banned school children from outdoor exercises until January 2025, while also halting construction work and restricting office hours for employees of both government and private firms.
