CAGAYAN DE ORO CITY — The Philippine Army’s 401st Infantry Brigade of the 4th Infantry (Diamond) Division, in coordination with the Philippine National Police (PNP), has declared Eastern Mindanao insurgency-free following the surrender of the remaining New People’s Army remnants in the area.

The announcement came after sustained operations in areas previously influenced by the dismantled Northeastern Mindanao Regional Committee, including the surrender of five former members of the Communist Terrorist Group on 2 June 2026 in Barangay Sibahay, Lanuza, Surigao del Sur.

A joint intelligence operation was conducted by the 36th Infantry Battalion, 3rd Special Forces Battalion and the 1st Special Action Battalion of the PNP Special Action Force.

The surrenderers turned over one RPK light machine gun, three M16A1 rifles, one M203 grenade launcher, one M4 Bushmaster short-barrel rifle, ammunition, magazines, tactical gear, and subversive documents.

401st Infantry Brigade Acting Commander Col. Glenn Joy Aynera said the development reflects sustained clearing operations and close coordination with partner security forces, resulting in the continued recovery of loose firearms and war materiel.

4th Infantry Division Commander Maj. Gen. Marion Angcao said the success highlights the effectiveness of sustained operations in former insurgency-affected areas and strong inter-agency cooperation.
