Malaysia has declared an emergency in a town in Sarawak state due to hazardous air pollution linked to forest and peat fires in Indonesia. The Air Pollutant Index in Serian reached 521 on Friday, exceeding the country's emergency threshold, while Kuching showed a reading of 311. Indonesian authorities have arrested 112 people suspected of starting recent forest and peatland fires, with 167 cases being investigated involving over 4,700 hectares of land burned across nine provinces. The haze is a recurring seasonal problem in Southeast Asia, where smoke from Indonesian fires can travel to neighboring countries, including Malaysia, Brunei, and Singapore.

Story summary
Malaysia has declared an emergency in the town of Serian, with a population of around 90,000, due to severe air pollution caused by haze from Indonesia's forest and peat fires. The Air Pollutant Index (API) in Serian surged to 521, exceeding the country's emergency-level threshold, while nearby Kuching showed a hazardous reading of 311. This is not an isolated incident, as haze is a recurring seasonal problem in Southeast Asia affecting neighboring countries such as Singapore, Brunei, and Malaysia. The Indonesian authorities are investigating 167 cases of deliberate burning of land across nine provinces, involving around 4,700 hectares of land. The emergency declaration allows for more effective measures to be taken, including potentially halting nonessential work and outdoor activities if the API remains above 500.
