On Sunday, January 25, 2015, three platoons of the elite SAF police squad entered the guerrilla enclave of Tukanalipao, Mindanao, Philippines, with the goal of detaining two high-ranking Jemaah Islamiyah-affiliated, improvised-explosive-device experts, Zulkifli Abdhir (also known as Marwan) and Abdul Basit Usman. The SAF troops raided the hut where they believed Marwan was located, and the man they believe to be Marwan engaged them in a firefight and was killed. The SAF initially planned to take his body for identification. However, the shooting alerted the BIFF and MILF 118th Command in the area. The SAF had no time to retrieve the body so they just cut off a finger, took a photo, and left his body there. By 6:18 AM UTC+8 (PST), an SMS message was sent by the Commander of SAF 61D Battalion to SAF Director Getulio Napeñas that they were pinned down at coordinates 6.92489°N 124.52047°E.[4] What followed was a bloody encounter that left 44 SAF, 18 MILF, and 5 BIFF dead.
