Heavy smoke from forest fires has resulted in the worst pollution for over ten years in southern Thailand.
The smoke has threatened local people's health in seven provinces in the south.
Dangerous levels of pollution were recorded in the Thai city of Songkhla.
Earlier this month, a number of flights to Phuket were cancelled because of the smoke.
In the past two months, thousands of forest fires in Indonesia have left bad effects on Southeast Asia.
Pollution has also increased rates of respiratory illnesses.
