BBC visits wildfire front in haze-choked Indonesia

As Indonesia battles its worst wildfire season in a decade, a toxic haze is choking millions of residents in the region.

The BBC's Liza Tambunan is in central Kalimantan, where air pollution levels have plunged to hazardous levels.

The haze has been linked to hundreds of thousands of respiratory illnesses in Indonesia, and has drifted to neighbouring countries like Singapore and Malaysia.
