The 47-year-old suspect, whose identity has not been officially confirmed by authorities, was arrested at Sydney Airport after arriving on a domestic flight from Brisbane, Australian Federal Police Commissioner Krissy Barrett said.

He is due to appear in a Sydney court later on Tuesday.Police allege the victims were not taking part in hostilities at the time of their deaths and were detained, unarmed, and under the control of members of the Australian Defence Force.

Barrett said the accused either directly carried out the shootings or ordered subordinate personnel to do so.The charges come as part of a broader investigation into alleged misconduct by elite Australian forces in Afghanistan.

A landmark 2020 military inquiry found credible evidence that special forces personnel unlawfully killed 39 Afghan prisoners, farmers, and other noncombatants.Barrett said the latest case involved only a limited number of personnel and emphasized that the allegations did not reflect the conduct of the wider military.

She described the accused actions as confined to “a very small section” of the defence force.The Office of the Special Investigator, established to examine war crimes allegations, has reviewed 53 incidents to date, with 39 cases concluding without charges, according to its director Ross Barnett.

The case follows separate proceedings against former SAS soldier Oliver Schulz, who has pleaded not guilty to a charge of war crime murder over the alleged killing of an Afghan man in Uruzgan province in 2012.

War crime murder is a federal offense in Australia and carries a potential sentence of life imprisonment. Around 40,000 Australian personnel served in Afghanistan between 2001 and 2021, during which 41 troops were killed.

The assault occurred in Bafwakoa village in Mambasa territory of Ituri province, near the town of Niania, beginning around 7 p.m. local time, according to army statements and local authorities.

The Congolese military said the attackers were members of the Allied Democratic Forces (ADF), an armed group active in eastern Congo that has been recognized by Islamic State as an affiliate.

Local official Christian Alimasi said the attackers burned at least 44 houses, killed residents using machetes and fire, and abducted two people during the raid.

Violence linked to the ADF has intensified in recent months in Ituri and neighboring North Kivu province, despite joint military operations launched in 2021 by Congolese and Ugandan forces to counter the group.

Data from Insecurity Insight shows the ADF accounted for roughly a quarter of reported violence against civilians in eastern Congo between 2020 and 2025, underscoring the persistent security challenges in the region.
