JAKARTA, Indonesia (AP): Indonesian authorities have arrested 72 people suspected of starting some of the forest and peatland fires as huge blazes in central and west Indonesia triggered choking haze.
Indonesia has been battling fires driven by an intensifying El Niño pattern and a prolonged dry season, generating dense smoke that crossed into Malaysia, according to Indonesia's National Disaster Management Agency, or BNPB.
Fires are a regular problem in Indonesia that strain relations with neighbouring countries.
Plantation owners and traditional farmers often start fires to clear land for farming, said Mohammad Irhamni, director of special crimes at the National Police's Criminal Investigation Agency.
The arson suspects were being investigated in connection with 89 forest and land fire cases across five provinces on the island of Borneo and four on Sumatra, Irhamni said.
He said most of the suspects were accused of deliberately burning land to clear areas for plantations at lower cost. Investigators were still tracing financial records to determine whether companies financed or ordered the land clearing, signalling the probe could expand beyond those arrested.
"We will not stop at the perpetrators on the ground," Irhami said in a news conference in Jakarta on Sunday (Aug 23).
"We will determine who benefited from these activities and who was ultimately behind them."
The suspects face charges that carry penalties ranging from hefty fines to prison terms of up to 15 years, he said.
Blazes on Sunday blanketed parts of Borneo, the world's third-largest island shared by Indonesia, Malaysia and Brunei. Indonesia administers about three-quarters of the island, where the country's Environment Ministry recorded more than 3,700 hot spots on Sunday.
BNPB chief Suharyanto said fire activity had increased in West, Central and South Kalimantan provinces on Borneo, where many blazes worsen due to peatlands, prolonging haze in several areas.
"Land that appears extinguished on the surface may still contain embers underneath, so sufficient rainfall is crucial to rewet the peat and fully suppress the fires," said Suharyanto.
The western island of South Sumatra also battled blazes, with more than 1,700 hot spots detected on Sunday, causing choked haze and reducing visibility to only 10m in some areas, the ministry said.
Cloud-seeding operations resumed over Kalimantan on Sunday, deploying 30 helicopters for water-bombing and aerial patrol missions over Kalimantan and another 22 helicopters covering Sumatra.
Meanwhile, Malaysia has suffered severe smoke from the blazes, with its eastern state of Sarawak among the hardest hit. One district recorded "very unhealthy" air quality Friday, while eight others posted unhealthy readings, prompting the closure of nearly 600 schools and affecting about 200,000 students, the Sarawak government said. – AP
