Philippine troops battling militants on a central resort island killed a young Abu Sayyaf commander who was involved in the beheadings of two Canadians and a German and who had sailed far from the extremists' southern jungle hideouts to capture more hostages, the military chief said on Wednesday. Military chief of staff Gen. Eduardo Ano said that troops recovered and identified the remains of Moammar Askali at the scene of the battle in a coastal village on Bohol island. Five other Abu Sayyaf gunmen, three soldiers and a policeman also were killed in Tuesday's clashes. Ano said captured Abu Sayyaf militants identified Askali from a photo troops took of the young militant leader after death, which confirmed that the gunmen who quietly cruised into Bohol on three motorboats Monday night then clashed with troops belonged to the extremist group. Askali, who used the nom de guerre Abu Rami, had partly served as an Abu Sayyaf spokesman in recent years. "This is a major blow to the Abu Sayyaf," Ano said. "If they have further plans to kidnap innocent people somewhere, they will now have to think twice." Askali was an emerging hard-line leader of Abu Sayyaf and had pledged allegiance to Daesh (the so-called IS). He had received bomb-making training from Malaysian Zulkifli bin Hir, or Marwan, a top Southeast Asia militant leader who was killed in 2015, according to a police profile. It was Abu Sayyaf's first known attempt to carry out ransom kidnappings deep in the central Philippine heartland, far from the group's jungle lairs in the southern provinces of Sulu and Basilan. Ano said the troops were still hunting at least five Abu Sayyaf gunmen, though fighting had eased Wednesday. While the bold kidnapping attempt appears to have been foiled, the militants' success in penetrating the bustling region of beach resorts and other popular attractions could raise concern among tourists and businessmen. Bohol island lies about 640 km southeast of Manila and is about an hour by boat from Cebu province, a trade and tourism center which has hosted some of the meetings of the Association of Southeast Asian Nations, the regional bloc the Philippines is leading this year. Ano said military intelligence operatives had been trying to track the movements of Askali's group for several days after learning of their planned abductions. The gunmen traveled on motorboats along a river to Inabanga's Napo village, where government forces assaulted them, military spokesman Col. Edgard Arevalo said, adding that troops recovered four rifles and a homemade bomb from the dead gunmen. The US Embassy in Manila had earlier advised Americans to take precautions amid "unsubstantiated yet credible information" of possible kidnappings by terrorists in Bohol and other central areas. The United States and the Philippines both list Abu Sayyaf as a terrorist organization for bombings, kidnappings for ransom and beheadings. Abu Sayyaf militants have crossed the sea border with Malaysia on powerful speedboats and kidnapped scores of foreign tourists in past years, reflecting their growing capability and desperation for money. In 2001, they sailed as far as western Palawan province, where they seized 20 people, including three Americans, from a resort. — AP
