One killed in Indonesia helicopter crash during firefighting operation

One person has died after a helicopter crashed into a river in Indonesia during a mission to fight wildfires in South Kalimantan.

An Indonesian crew member was killed, while two others on board - an Australian and New Zealander - were "found safe" and taken to hospital for treatment, according to Indonesia's disaster mitigation agency.

Investigations into the accident are ongoing, the agency said on Sunday, adding that it could continue its firefighting operations.

For months, parts of Indonesia have been battling wildfires that have shrouded large swathes of South East Asia in toxic haze. The blazes in forests and peatlands are fuelled by a dry season that has been exacerbated by El Niño.
