Punjab capital Lahore on Wednesday remained covered in thick and grey smog, heavily loaded with pollutants which affected the air quality.

Smog, which is not a natural phenomenon, is generated because of unregulated industrialisation and urbanisation. Smog causes severe affect on people like itchy skin, blurred vision, headache and heavy breathing.

People also criticised the provincial government's policies to cut down trees for development projects.

Punjab Chief Minister Shahbaz Sharif formed a committee to examine the prevailing weather of dense smog in the cities and plains of Punjab.

The Newly formed committee consists of adviser to chief minister on health, minister for environment, chief secretary Punjab and 16 other government officials.

The chief minister also directed the committee to meet immediately and suggest the precautionary measures the people should take.
