MANILA, April 27, (Agencies): Philippine President Benigno Aquino vowed Wednesday to launch a military assault aimed at “neutralising” Islamic militants who beheaded a Canadian hostage and are holding more than 20 other foreigners. “Casualties are to be expected.

But what has to be of utmost importance is neutralising the criminal activities of the ASG,” Aquino said in a statement, referring to the Abu Sayyaf militant group by a commonly used acronym. Aquino released the statement after the severed head of Canadian John Ridsdel, kidnapped seven months ago from aboard a yacht, was dumped Monday on a street on Jolo, a remote southern island that is one of the Abu Sayyaf’s main strongholds. “This murder was meant to terrorise our whole population.

The Abu Sayyaf thought they could instill fear in us. Instead, they have galvanised us even further to ensure justice is meted out,” Aquino said. “We have always been open to talks with those who desire peace, but those who commit atrocities can expect the full might of the state.” He did not give a timeframe for the assault. The Abu Sayyaf militants, whose leaders have pledged allegiance to the Islamic State group, are holding more than 20 other foreigners captive.

These include another Canadian, a Norwegian man and a Filipina who were abducted at the same time as Ridsdel at a marina near Davao, the biggest city in the southern Philippines and about 600 kms (370 miles) from Jolo. The Abu Sayyaf is also believed to be holding a Dutch birdwatcher kidnapped from a southern Philippine island in 2012, as well as 18 Indonesian and Malaysian sailors abducted over the past month. Aquino said the captives were under the control of Radullan Sahiron, one of the Abu Sayyaf’s founders who is famous for losing one arm in battle against the military. He said Sahiron had consolidated his forces around himself and the captives in Sulu, a small Muslim-populated archipelago about 1,000 kms from Manila. Jolo is the biggest island in Sulu.

“This presents both a problem and an opportunity. It is a problem because of the sizeable force surrounding Sahiron and the captives, but it is also an opportunity because smashing these forces is within our grasp,” Aquino said. The Abu Sayyaf is a radical offshoot of a Muslim separatist insurgency in the south of the mainly Catholic Philippines that has claimed more than 100,000 lives since the 1970s. It is believed to have just a few hundred militants but has withstood repeated US-backed military offensives against it, surviving by using the mountainous, jungle terrain of the southern islands to its advantage. Although the Abu Sayyaf’s leaders have pledged allegiance to IS, analysts say they are mainly focused on their lucrative kidnappings-for-ransom rather than setting up an Islamic caliphate. Abu Sayyaf gangs have earned many millions of dollars from kidnapping foreigners and locals since the early 1990s.

WindfallsOne of the Abu Sayyaf’s biggest recent windfalls is believed to have come in 2014 when it claimed to have been paid more than $5 million for the release of a German couple abducted from aboard their yacht in the southwest Philippines. Aquino also revealed a series of alleged Abu Sayyaf plots to kidnap Filipino boxing hero Manny Pacquiao and the president’s younger sister, Kris, a popular television personality. He said Isnilon Hapilon, who Islamic State has recognised as a local Filipino leader, was behind these plots. He said Hapilon and other Abu Sayyaf leaders had wanted to conduct the kidnappings, conduct bombings in Manila and even assassinate himself so that IS would give them funds and resources.

He reassured the public that key leaders involved in these plots had been arrested and those threats had been put “to bed”. However he also said Hapilon was on Basilan island, the other key Abu Sayyaf stronghold neighbouring Jolo, and that military assaults against him were continuing. On April 9, 18 Filipino soldiers were killed as they waged a day-long battle against Abu Sayyaf gunmen on Basilan. Also Wednesday, the Philippines said it was considering launching joint sea patrols with Malaysia and Indonesia in the waters where the recent kidnappings of the sailors occurred.

Meanwhile, Philippine police forensic experts were checking if a headless body of a Caucasian man found by villagers in a southern province is that of a Canadian hostage beheaded this week by Muslim extremists, offi cials said Wednesday. The body was found beside a dry creek in a mountainous clearing near Talipao town in Sulu province, where Abu Sayyaf militants beheaded John Ridsdel after failing to get a huge ransom by a Monday deadline. Suspected militants later dumped Ridsdel’s head in Sulu’s Jolo town.

Canadian Prime Minister Justin Trudeau condemned the brutal killing of Ridsdel, who was kidnapped with a fellow Canadian, a Norwegian and a Filipino woman from a southern marina on Samal island in September and taken by boat to Sulu. In Canada, Trudeau said he spoke with Philippine President Benigno Aquino III about possible actions against the kidnappers. “The discussions I had with President Aquino and are continuing to have with our allies in the Philippines is the need to bring these criminals to justice and to do whatever we can to express that we are very concerned about security of Canadians,” Trudeau said. The Canadian leader stressed that “we will not pay a ransom”. Under increased pressure, thousands of troops have been searching for the militants and their remaining 22 foreign captives, including those abducted with Ridsdel. They face a dilemma of how to wage an offensive against about 400 militants in Sulu’s vast jungle without endangering the hostages

ManhuntAbout 2,000 military personnel, backed by UH-1 “Huey” and MG520 rocket-fi ring helicopters and artillery, are involved in the manhunt for the militants, who are believed to be massing in Sulu’s mountainous Patikul town, military offi cials said. Amid the crisis, a top army offi cial in Sulu, Brig Gen Alan Arrojado, resigned Tuesday from his brigade “due to confl ict of approach in addressing the Abu Sayyaf threats” in the province. He did not elaborate.

The Abu Sayyaf began a series of large-scale abductions after it emerged in the early 1990s as an offshoot of a separatist rebellion by minority Muslims in the southern Philippines. It has been weakened by more than a decade of government offensives, but has endured largely as a result of large ransom and extortion earnings. The United States and the Philippines have both listed the group as a terrorist organization. In related news, On Wednesday, army spokesman Major Filemon Tan said a headless body was found in a dried creek, near the jungles where Ridsdel was believed to have been beheaded by militants belonging to the Abu Sayyaf group.
