Just across the border in Malaysia, the state of Johor has shut all schools for two days due to worsening air quality.
The schools have been closed since yesterday, with the air quality in the Johor town of Batu Pahat reaching "very unhealthy" levels earlier this week and registering the worst readings in the country this season.
