A massive forest fire in Indonesia has worsened the air pollution levels in several parts of the Southeast Asian region. The blaze, caused by drought and land-clearing operations, brought haze not only to the skies of Indonesia, but also in Malaysia and Singapore.

Haze is a recurring problem which is blamed by many on slash and burn practices of small farmers and big palm oil plantations. Indonesia has vowed to go after these individuals and companies to stop the burning of the forest.

Meanwhile, the fire is still spreading in the western part of Indonesia, and the smoke continues to descend in several cities of the country and in nearby Malaysia and Singapore.

Below are some photos which show how residents of the region are suffering from the impact of the haze.

Singapore

Singapore’s National Environment Agency issued this advisory on September 17, 2015, about the health impact of the haze:

Given the air quality forecast for the next 24 hours, healthy persons should reduce prolonged or strenuous outdoor physical exertion. The elderly, pregnant women and children should minimise prolonged or strenuous outdoor physical exertion, while those with chronic lung or heart disease should avoid prolonged or strenuous outdoor physical exertion. Persons who are not feeling well, especially the elderly and children, and those with chronic heart or lung conditions, should seek medical attention.
