The resultant unhealthy air quality in Singapore caused by the Indonesian fire pushed the Republic higher in the list of top 10 world's most polluted cities though the condition briefly improved last night. The Malaysian government is seriously considering creating artificial rain by using drones to combat the haze in the country.

It should be noted that in Singapore, the air quality improved overnight with 24-hour Pollutant Standards Index (PSI) readings and one-hour PM2.5 concentrations showing a decline as of Friday morning data.

Tun Dr Mahathir said at a press conference, "We have a suggestion to use drones to form artificial rain... We can use several drones at one time and deploy in a particular area such as Putrajaya which is badly affected by haze."

It should be mentioned that a total of 2,646 schools in Malaysia will be closed on Friday due to poor air quality, which means that over 1.7 million students will be affected.
