BANGKOK — Thai authorities here closed over 350 schools in Bangkok on Friday in response to hazardous air quality, local media reported.
The Bangkok Metropolitan Administration announced the closure of all 352 schools, switching to online classes as PM2.5 levels reached 108 micrograms per cubic meter—well above safe limits.
Bangkok is currently the fourth most polluted city in the world, according to Swiss-based monitor IQAir. This marks the largest school closure since 2020, when all 437 schools were shut down due to pollution.
