Authorities on Tuesday released the CCTV footage showing what are believed to be the suspects in the January 27 twin bombing attacks on a cathedral in Jolo, Sulu.
According to Lieutenant Colonel Gerry Besana, spokesperson for the military's Western Mindanao Command, the footage shows the three suspects possibly in the act of detonating the second bomb.
One of the men in the footage, the one wearing a blue-green jacket, was identified as Alyas Kamah, who was seen giving something to a companion before running moments after the blasts.
Interviewed on Dobol B sa News TV earlier in the day, Philippine National Police chief Director General Oscar Albayalde said Kamah is a member of Ajang-Ajang, a group affiliated with the Abu Sayyaf.
The military is asking residents of Jolo to help determine the suspects' whereabouts.
Twenty-one people were killed in the bombing attacks while almost 100 others were wounded.
Malacañang has vowed to destroy those behind the two bombings — the first inside the cathedral and was followed by a second blast outside, which was detonated as security forces raced to the scene.
Following the deadly blast, security forces had placed the town of Jolo under lock-down. —Jonathan Andal/KBK, GMA News
