The bodies of the sailors, Hoang Thong and Hoang Va Hai, were found Wednesday by villagers in the town of Sumisip, said the military’s Western Mindanao Command. Pictures showed their decapitated heads beside their bodies.
The two were among six crewmen of the Vietnamese cargo vessel MV Royal 16 taken captive by gunmen in November in the waters off Basilan, part of a wave of sea assaults alarming the region’s leaders.
One of the six crewmen was rescued in June. Three others are still being held captive.
