Kumurkek, Southwest Papua. A suspected attack by the Free Papua Movement (OPM) killed two Indonesian soldiers in South Aifat district, Maybrat regency, on Sunday, a military official said.

The incident underscores ongoing security tensions in the restive region, where clashes between Indonesian forces and separatist groups have persisted for decades.

Following the incident, security forces have heightened vigilance and are planning to deploy additional troops to the area, according to Brig. Gen. Slamet Riyadi, commander of Military Command 181 in Southwest Papua.

“After this incident, we have increased alert levels, mapped vulnerable areas, and tightened field surveillance,” Slamet said. “Additional troop deployments are being planned, along with strengthened intelligence operations.”

Identities of the slain soldiers were not disclosed.

In a separate statement, OPM spokesperson Sebby Sambom claimed responsibility for the attack.

“We also seized two firearms and military logistics,” Sebby said.

According to the group, the attack was carried out by armed fighters led by Denny Moos while Indonesian troops were conducting a routine patrol. The spokesperson also called on security forces to halt military operations in Papua and urged them not to intimidate civilians.
