Malaysia has closed schools in its capital and several surrounding regions as thick smoke from Indonesian forest fires pushed air pollution to unhealthy levels. The closure order affected schools across Kuala Lumpur, the administrative capital Putrajaya, and the states of Johor, Malacca, Negeri Sembilan, Pahang, and Selangor.
The widespread measure impacted roughly two million students and followed a government-run Air Pollutant Index reading of about 170 in Kuala Lumpur. Meanwhile, air quality further south in Singapore dropped into the very unhealthy range according to independent trackers.
Malaysian Prime Minister Anwar Ibrahim described the haze situation as deeply worrying and noted he had spoken with Indonesia’s President Prabowo Subianto, who agreed to take necessary steps. Anwar also requested that Malaysia’s foreign minister push for an urgent meeting of regional environment ministers while the country ramps up cloud-seeding operations to induce rain.
King Sultan Ibrahim emphasized that appropriate measures must be enacted by relevant agencies to safeguard students, senior citizens, and individuals with respiratory conditions. Under official guidelines, schools are mandated to close once air pollution readings reach 150 or higher. Readings above 100 are deemed unhealthy, while levels surpassing 500 trigger a local emergency declaration.
Education Minister Fadhlina Sidek acknowledged the disruption and assured parents that future closures would be announced with more advance notice. The heavy smoke stems from what has become Indonesia's worst fire season in over a decade, driven by dry season conditions and El Nino pressures.
Fires have already scorched at least 200,000 hectares across six Indonesian provinces. Indonesia’s Ministry of Health has documented more than 170,000 respiratory infections, though the true count is believed to be higher because the data only accounts for individuals who sought formal medical care.
The regional haze has also raised concerns for organizers of Singapore's upcoming Formula One racing weekend. Event planners have stated that the races will proceed as scheduled, supported by extra medical personnel and face masks for attendees, maintaining that the conditions do not pose an immediate threat.
