Singapore air turns unhealthy again as haze from Kalimantan fires persist
Singapore is experiencing unhealthy air quality levels due to transboundary haze caused by forest fires in Kalimantan and Sumatra. Authorities have advised the public to reduce strenuous outdoor activities, particularly for vulnerable groups, as smoke plumes continue to drift into the region.
Why it matters
