[39][40][41][42] Several hundred U.S. soldiers were stationed in the area primarily to train Filipino troops in counter-terror and counter-guerrilla operations, but, following a status of forces agreement and under Philippine law, they were not allowed to engage in direct combat.

[45][46] Since the "All-Out-War" directive was issued in 2019 during the term of President Rodrigo Duterte over continuous attacks perpetrated by Abu Sayyaf towards civilians, especially after the Jolo Cathedral bombings, this has greatly diminished the terror group, with many of their leaders and members being killed and arrested, while former followers who returned to normal lives were reintegrated into society after serving their time in prison and undergoing rehabilitation.

[57][60][64][65] On 14 March 2005, inmates from the Abu Sayyaf Group rioted inside Camp Bagong Diwa in Taguig in an apparent escape attempt and barricaded the second floor of the building, leading to a standoff which ended the next day when government forces stormed the prison.

[82] On July 6, 2024, President Bongbong Marcos commended the joint efforts and sacrifices that resulted in the weakening of Abu Sayyaf during his visit to the headquarters of the 11th Infantry Division (ID) at Camp Teodulfo Bautista in Jolo, Sulu.

[85] The Philippine government is currently working continuously to revitalize and rejuvenate the dark image of former Abu Sayyaf strongholds with the restoration of peace and increased security with social and economic development for the inhabitants.

[74] Two kidnapping victims, (Martin and Gracia Burnham) who were kept in captivity by ASG for over a year, "gently engaged their captors in theological discussion" and found Abu Sayyaf fighters to be unfamiliar with the Qur'an.

[119] Most Abu Sayyaf victims have been Filipinos; however, in recent years (especially from 2011 onwards), Australian, British, Canadian, Chinese, Dutch, French, German, Indonesian, Japanese, Korean, Malaysian, Norwegian, Swiss and Vietnamese nationals have been kidnapped or attacked.

In 2000, Abu Sayyaf captured an American Muslim and demanded that the United States release Sheikh Omar Abdel Rahman and Ramzi Yousef, who were jailed for their involvement in the 1993 World Trade Center bombing in New York City.

On August 31, 2000, American citizen and Muslim convert Jeffrey Schilling from Oakland, California, was captured on Jolo while visiting a terrorist camp with his new wife, Ivy Osani (a cousin of Abu Sabaya, one of the rebel leaders), whom he had met online.

[128] On May 27, 2001, an Abu Sayyaf raid kidnapped about 20 people from Dos Palmas, an expensive resort in Honda Bay, taking them to the north of Puerto Princesa City on the island of Palawan, which had been "considered completely safe".

The most "valuable" hostages were three North Americans, Martin and Gracia Burnham, a missionary couple, and Guillermo Sobero, a Peruvian-American tourist who was later beheaded, following a $1 million ransom demand.

After returning to Mindanao, Abu Sayyaf conducted numerous raids, including one that culminated in the Siege of Lamitan and "one at a coconut plantation called Golden Harvest; they took about 15 people captive there and later used bolo knives to hack the heads off two men.

On October 11, 2009, Irish Catholic missionary Michael Sinnott, aged 79, from Barntown County Wexford was kidnapped from a gated compound in Pagadian, the capital of Zamboanga del Sur province, suspected to be part of ASG and some renegade members of MILF.

A classified document obtained by Rappler lists Ito first, saying he was held captive by Abu Sayyaf's most senior leader, Radullan Sahiron, in Langpas, Indanan, Sulu early in 2013.

[149][150] Warren Richard Rodwell, a former Australian Army soldier and university English teacher,[151] was shot through the right hand when seized[152] from his home at Ipil, Zamboanga Sibugay on the island of Mindanao in the southern Philippines on December 5, 2011[153] by ASG militants.

[166] In May 2015, ex-Philippine National Police (PNP) officer Jun A. Malban, alias Michael Zoo,[167] was arrested in Kota Kinabalu, Malaysia, for the crime of "Kidnapping for Ransom" after Rodwell identified him as the negotiator/spokesperson.

[168] The director of the Anti-Kidnapping Group (AKG) stated that Malban's arrest resulted from close co-ordination by the PNP, National Bureau of Investigation (Philippines) and Presidential Anti-Organized Crime Commission with the Malaysian counterparts and through Interpol.

[170] In August 2015, Edeliza Sumbahon Ulep,[171] alias Gina Perez, was arrested at Trento, Agusan del Sur during a joint manhunt operation by police and military units.

[172] In August 2016, The Manila Times reported the arrest of the kidnap-for-ransom group of Barahama Alih sub-leader, Hasim Calon alias Husien (also a notorious drug dealer), in his hideout in Tenan village in Ipil town.

He was linked to the kidnappings of Rodwell in 2011, Irish missionary Michael Sinnott in 2009 in Pagadian City, and Italian Catholic priest Giancarlo Bossi in Zamboanga del Sur's Payao town in 2007.

Military sources allege Barahama Alih Group was responsible for a number of kidnapping incidents in previous years including the abduction of Australian national Warren Rodwell, Italian priest Giancarlo Bossi, and some local Filipinos.

More were expected to yield because of the regional government's Program Against Violence and Extremism (PAVE), designed to provide opportunities and interventions, including psychosocial sessions, medical check-ups, introduction to farming systems, and expository tours outside the island provinces to facilitate the reintegration of former combatants into society.

The provincial director of the Criminal Investigation and Detection Group (CIDG) said Aburi was involved in the 2011 kidnapping of Australian national Warren Rodwell and the 2019 abduction of the Hyrons couple in Tukuran, Zamboanga del Sur.

[165] In February 2021, The Manila Times reported that Abu Sayyaf subleader Arrasid Halissam was shot dead when he opened fire on police serving a warrant on him in the village of Santa Maria, Zamboanga City.

Halissam was linked to numerous kidnappings such as Australian adventurer Warren Rodwell, Americans Gerfa Lunsmann and son Kevin, Chinese Yuan Lin Kai and Jian Luo, South Korean Nwi Seong Hong, and almost a dozen Filipinos.

[186] Police subsequently charged Ibni Basaludin, Yug Enriquez, Brahama Ali, and Ging-Ging Calon, all residents of Barangay Tenan, Ipil, Zamboanga Sibugay with kidnapping with serious illegal detention.

On April 8, 2016, Del Torchio was released and found at Jolo port aboard MV KC Beatrice bound for Zamboanga City after his family paid P29 million ($US650,000) in ransom.

[111][201] On October 4, 2019, armed men abducted British national Allan Hyrons and his Filipina wife Wilma from their beach resort in Tukuran town, Zamboanga del Sur province on the southern island of Mindanao.

OIC Secretary General Azeddine Laraki told the Philippine government he was prepared to send an envoy to help save the hostages and issued a statement condemning the rebels.

[337] In early 2019, Duterte emphatically stated that he would never initiate or agree to any peace talks with Abu Sayyaf due to his detestation for the group's record of atrocities and its treatment of innocent people as young as 8 years old.
