In May 2003, The municipality was attacked by 150 Moro Islamic Liberation Front (MILF) guerrillas and Abu Sayyaf.[6] The attacked commenced at 12 AM in MAY 4. Small group of policemen led by 27-year-old police senior inspector Ranie Planilla Hachuela defended Siocon that lasted nine hours. Hachuela managed to rally his men in putting up stiff resistance against the wave of attacks by the rebels trying to overrun the municipal hall, police station and hospital. For this reason he was awarded the Medal of Valor for risking his life and for rescuing the town mayor and his family.

The rebel created a bullet proof plan of securing the entry and exit of the Poblacion (town center). Responding government troops were ambushed as they tried to aid the policemen who were so unmanned at the moment.

That frightening feeling was expressed by wiljun cubero as he narrated how the rebels stormed the municipal hall and fire station right next to their house at Micubo's compound.

13 of the 150 rebels were killed including Jairullah Hassan aka Commander Hairon of the MILF who headed the attacked.

In the case of casualties, eleven government troops and 25 civilians lost their lives in the assault including two seminarians.[7] Public market was burned down and civilians were taken out from their home as a human shield as rebels withdraw. Some hostages were later released hours after while other strongmen were held for days as they were tasked to carry the rebel's wounded fellow in the thick forest in the municipality of Sibuco.

The day after the attached, MILF spokesman Eid Kabalu expressed that the attacked was a show of force by the MILF and Abu Sayyaf with in the area.
