West Papua: Separatist attacks on aviation highly likely to continue over the near to medium term

On 3 July, the West Papua National Liberation Army (TPNPB) claimed responsibility for killing an American commercial pilot after his aircraft landed in Sobaham District, Yahukimo Regency, claiming it was used to transport Indonesian military personnel. Indonesia's military recovered the pilot's body, confirmed all seven Papuan passengers escaped unharmed, and denied the aircraft was transporting troops. TPNPB stated the attack was intended as a message to the Indonesian and US governments over the Papua conflict and warned it would continue targeting civilian aircraft it accused of supporting military operations. The TPNPB attacked aircraft in the same district in January 2026 (see SPI 39, 14–27 January), and kidnapped a New Zealand pilot in the same province in 2023.

Assessment: The attack reinforces the ongoing escalation in West Papua since May 2025 (see SPI 44, 25 March–7 April 2026). The attack demonstrates TPNPB's continued intent to target civilian aviation it believes supports Indonesian security operations, including foreign nationals (see SPI 41, 11–24 February 2026). Indonesian security operations and TPNPB attacks on aviation are highly likely to continue over the near to medium term, increasing the risk to foreign personnel and businesses operating in remote areas of West Papua.
