Malaysia sends aircraft and helicopters as Indonesia battles worst wildfires in 11 years

Indonesia has accepted Malaysian assistance to fight forest and land fires that have been burning for weeks across Kalimantan, with President Prabowo Subianto saying Malaysia will provide three helicopters, an aircraft and 52 personnel. The deployment adds to assistance already accepted from Japan as Indonesia confronts what Reuters describes as its most intense wildfire season in 11 years. Smoke from the fires has spread across national boundaries, worsening air quality in parts of Malaysia and Singapore and turning an Indonesian environmental emergency into a regional public-health problem.

Malaysia’s disaster authorities said the offer includes a Bombardier CL-415MP amphibious firefighting aircraft operated by the Malaysian Maritime Enforcement Agency, three helicopters and a 52-member team. Malaysian Deputy Prime Minister Ahmad Zahid Hamidi described the fires and transboundary haze as a shared regional challenge rather than an issue to be handled through mutual blame. Prabowo said the assistance was welcome because environmental impacts from fires inside Indonesia are being experienced by neighbouring countries.

How severe are Indonesia’s 2026 forest and peatland fires?

The 2026 fire season has become Indonesia’s most severe in more than a decade, amplified by exceptionally dry conditions associated with a powerful El Niño. Reuters reported that approximately 800,000 hectares had burned by August and that more than 12.5 million people across seven provinces had been exposed to hazardous haze. Respiratory cases in affected areas rose from 50,891 to 113,336 within a little more than a week as smoke concentrations intensified.

Indonesia’s meteorological agency identified thousands of high-confidence hotspots during early September, including 2,526 in Central Kalimantan, 2,102 in West Kalimantan and 1,180 in South Sumatra over a ten-day monitoring period. BMKG said extremely strong El Niño conditions were supporting unusually dry weather and warned that peat fires can persist beneath the surface even after visible flames are extinguished.

Why are peatland fires in Kalimantan so difficult to extinguish?

Peat consists of partially decomposed organic material that can accumulate over thousands of years and hold enormous quantities of carbon. When drained and dried, peat can ignite below ground and smoulder through thick layers of soil, making conventional surface firefighting much less effective. Flames may appear controlled while subterranean combustion continues and later resurfaces elsewhere.

This is why water-bombing aircraft alone cannot fully solve Indonesia’s fire problem. Fire crews need sustained saturation, ground access and sometimes weather modification to re-wet peat sufficiently, while preventing new ignition remains equally important. BMKG lists ongoing weather-modification operations specifically designed to wet peat and support wildfire suppression in several Indonesian provinces.

What exactly is Malaysia sending to help Indonesia?

Malaysia has offered one CL-415MP amphibious aircraft capable of scooping water from suitable surfaces, three helicopters and 52 personnel. Prabowo said the aircraft and crews would arrive soon, although he did not provide a precise deployment timetable in his September 18 remarks. Japan has already provided assistance, while other governments have also offered support.

Aerial resources can help reach fires located far from roads and accelerate suppression where ground crews cannot operate effectively. Helicopters can transport personnel as well as drop water, while specialised fixed-wing aircraft can deliver larger quantities across repeated sorties. Their usefulness still depends heavily on visibility, wind, available water sources and whether burning is occurring mainly at the surface or deep within peat.

How far has Indonesia’s haze spread into Malaysia and Singapore?

Reuters reports that smoke has already created unhealthy air conditions in neighbouring Malaysia and Singapore. Regional haze can travel hundreds of kilometres depending on wind direction and atmospheric conditions, meaning fires on Sumatra or Borneo can produce significant health effects outside Indonesia even when neighbouring countries have no major local fire activity.

Malaysia has experienced the issue repeatedly during severe Indonesian fire seasons, which explains the political sensitivity surrounding cross-border haze. This year’s response is notable for emphasising direct operational cooperation rather than public diplomatic confrontation. Malaysia’s disaster agency explicitly described the fires as a common challenge requiring close cooperation without blame.

Why are respiratory illnesses rising so rapidly during the haze?

Wildfire smoke contains fine particulate matter capable of penetrating deep into the lungs and entering the bloodstream. Exposure can worsen asthma, bronchitis and cardiovascular conditions while also affecting otherwise healthy people through coughing, sore throats, eye irritation and breathing difficulty. Children, older adults and people with existing respiratory disease generally face greater risk.

Reuters reported respiratory cases more than doubling to 113,336 in affected Indonesian provinces as haze worsened. Community responses have included distribution of masks, oxygen support and local “oxygen houses” for residents experiencing breathing problems. These health effects transform wildfire control from an environmental-management problem into an urgent healthcare and workplace-safety issue.

Could rain bring Indonesia’s fires under control soon?

Rain can substantially reduce surface fire activity and re-wet vegetation, but isolated rainfall does not necessarily extinguish deep peat fires. BMKG’s latest forecasts show some rainfall returning to parts of Kalimantan, including warnings for moderate to heavy rain in West Kalimantan and neighbouring regions over the coming days. That could aid firefighting, although conditions vary considerably across Indonesia’s enormous territory.

Indonesia’s Forestry Minister Raja Juli Antoni has warned that wildfire risk could persist until November, indicating that authorities are not relying on an immediate seasonal transition to solve the crisis. The duration will depend on rainfall distribution, El Niño conditions, ignition rates and the ability of crews to control peatland fires before they expand.

What are the key takeaways from Malaysia’s firefighting deployment to Indonesia?

Malaysia’s decision marks an escalation from monitoring cross-border haze to directly assisting Indonesian suppression operations. The deployment brings aircraft, helicopters and personnel into a fire season that has already affected millions of people and generated smoke across multiple countries. Indonesia’s acceptance of the support also reflects recognition that transboundary environmental emergencies increasingly require regional resources rather than exclusively national responses.

The fires will not be solved solely by additional aircraft because the underlying challenge includes drought, peatland conditions and repeated ignition. Nevertheless, aerial capacity can reduce the spread of active fronts and protect communities while Indonesia waits for more sustained rainfall. The most important measure of progress will be whether hotspot counts, burned area and respiratory illness begin falling simultaneously.

Why could the 2026 fires reshape Southeast Asian haze policy?

Severe haze episodes have repeatedly damaged relations within Southeast Asia because smoke crosses borders while fire prevention remains primarily a domestic responsibility. The scale of the 2026 crisis creates another opportunity to move toward shared firefighting capacity, faster deployment arrangements and stronger monitoring before smoke reaches major cities.

Malaysia’s practical intervention may therefore matter beyond this season. If joint operations prove effective, ASEAN governments could increasingly treat fire suppression in one member state as regional disaster management rather than foreign intervention. With El Niño projected to remain influential into early 2027, that cooperation may be required for longer than governments initially hoped.
