JAKARTA: Indonesia continues to battle forest and land fires across four provinces, with fires still affecting over 72ha.

Joint firefighting teams, backed by aerial support, extinguished nearly 3,800ha of forest and land fires across six priority provinces over the past week.

National Disaster Mitigation Agency (BNPB) Disaster Data, Information and Communication Centre acting head Berton Panjaitan said the remaining affected areas were in South Sumatra, Central Kalimantan, Jambi and West Kalimantan as of Wednesday.

"Integrated ground and aerial operations, including weather modification technology, continue to be optimised, with priority given to active fires, peatlands, subsurface fires, areas with high potential for spread, as well as airports and settlements," he said in a statement on Thursday.
