Local reports indicate that thick smog from rising levels of PM2.5 fine particles blanketed the city yesterday morning, forcing residents to wear face masks outdoors.

City governor Nirat Phongsittithaworn described this as a seasonal issue exacerbated by cross-border haze and local hotspots. Authorities have intensified wildfire control measures and public assistance efforts in response to the crisis.

Affected residents are advised to seek help from nearby public health hospitals, monitor updates, and adhere to government directives, according to Mr Nirat.
