Toxic wildfire haze spreads across South East Asia as 'super' El Niño intensifies

A blanket of toxic haze is enveloping parts of Indonesia and spreading into Malaysia, Singapore and the Philippines, as weeks-long wildfires continue to burn.

Millions of people across large swathes of South East Asia have been exposed to the smog, which in some areas has fuelled "acutely unhealthy" pollution more than 15 times the World Health Organization's recommended level.

Many of the ongoing fires have been burning across Sumatra and Indonesian Borneo since mid-July – underpinned by a so-called Super El Niño that is exacerbating drought conditions.

Between July and August, Indonesia's Health Ministry recorded over 50,000 cases of respiratory infections linked to land and forest fires.

More than 12,000 of those cases are of children under the age of five.

Rizma Nur Fatimah, a 19-year-old teaching assistant at a school in Banjarbaru, South Kalimantan, told the BBC that the smog in her classroom had become so thick "you couldn't even see your own feet".

"Even inside the house, with everything closed, the haze still got in," she said. "We've been living with this since I was born. It's the same every year, so we've almost become resigned to it. But this year is worse."

Misbah, a 23-year-old mother from nearby Pengayuan village, said her three-year-old daughter had developed "a cough, a sore throat and a runny nose" during the haze.
