JAKARTA, Indonesia (AP) — Indonesian police on Sunday arrested 72 people suspected of starting some of the recent forest and peatland fires as huge blazes in central and western parts of the country triggered a harmful cloud known as a choking haze.

Indonesia has been battling fires driven by an intensifying El Nino pattern and a prolonged dry season, generating dense smoke that crossed into Malaysia, according to Indonesia’s National Disaster Management Agency, or BNPB.
