Indonesia is battling its worst wildfires in more than a decade, with thick smog affecting millions of people and haze spreading to neighbouring countries.

Fires have been burning since last month across seven provinces on the islands of Borneo and Sumatra, while dry weather and drought linked to a "Super El Niño" are making them harder to contain.

Smoke from the fires, containing soot and tiny suspended particles, has produced haze across parts of Malaysia and Singapore.

The wildfires could continue through October or early November due to a forecasted late rainy season.

Haze contains tiny airborne particles about 30 times smaller than a human hair. These PM2.5 particles can penetrate deep into the lungs and sometimes enter the bloodstream, experts said.
