Malaysia is experiencing widespread haze, impacting air quality across the west coast of Peninsular Malaysia and portions of Sarawak. As of Tuesday, approximately 30 areas recorded unhealthy Air Pollutant Index (API) readings. Authorities report the haze is originating from multiple sources and drifting into the country. The situation is prompting concern for public health, particularly for vulnerable groups. No specific source of the haze has been officially identified yet, but cross-border movement is suspected. Residents are advised to take precautions and limit outdoor activities when possible. Monitoring continues as the haze situation evolves.
