Authorities in Bangkok are stepping up their fight against severe pollution that has left a cloud of smog hanging over the city.
Among the measures being taken is the launch of 50 drones for spraying water in the skies over the capital. The water will contain molasses to aid in the attachment to smog particles.
Thai Premier General Prayut Chan-o-cha is threatening to enforce pollution-control measures, which would prohibit people from driving alone, and ban the use of diesel cars.
With the air quality in Bangkok and nearby provinces continuing to worsen, and the level of fine and harmful particulate matter expected to remain well above the safe standards until this weekend, authorities have began imposing stricter measures.
The Bangkok Metropolitan Administration (BMA) has designated the city a pollution-control zone and asked schools and universities in the capital to be closed for two days.
