Malaysia declares an air-quality emergency in Serian, a district in its Sarawak state on Borneo, as hazardous haze from fires in neighboring Indonesia pushes pollution to critical levels. The Malaysian prime minister’s office and related authorities announce the emergency after air pollution reaches emergency-threshold readings reported by Malaysia’s environment agencies.

Several outlets say the smoke is linked to forest and peatland fires in Indonesia’s Kalimantan region and that the haze affects daily life in Serian, including reduced air quality that triggers emergency measures. One outlet reports pollution readings including an Air Pollutant Index (API) of 521 for Serian and 311 for Kuching. Euronews also notes that such cross-border haze is a recurring seasonal issue in Southeast Asia.

Some coverage focuses on the immediate emergency declaration, while later reporting adds that Malaysia lifts the haze emergency after a period, but continues to warn that very unhealthy air pollution risks remain. Others describe the haze as continuing to spread across homes and public areas during the emergency period.
