The United Nations has called for immediate and greater efforts to reduce air pollution in Pakistan, highlighting the alarming impact on children’s health. More than 11 million children under five years of age in Punjab province are exposed to toxic smog, the UN warned on Monday.

Punjab authorities have banned most outdoor activities and told some shops to shut early as smog-induced illnesses soar. Schools have also been closed to protect children, who are at high risk from the pollution.

Smog engulfs Punjab province, prompting lockdown-like measures due to severe pollution. Lahore ranks as the world's most polluted city, with major disruptions reported.
