Battle of Marawi

The Battle of Marawi (Labanan sa Marawi), also known as the Marawi siege (Pagkubkob sa Marawi) and the Marawi crisis (Krisis sa Marawi), was a five-month-long armed conflict in Marawi, Lanao del Sur, that started on 23 May 2017, between Philippine government security forces and militants affiliated with the Islamic State of Iraq and the Levant (ISIL), including the Maute and Abu Sayyaf Salafi jihadist groups. The battle also became the longest urban battle in the modern history of the Philippines.

According to the Philippine government, the clashes began during an offensive in Marawi to capture Isnilon Hapilon, the leader of the ISIL-affiliated Abu Sayyaf group, after receiving reports that Hapilon was in the city, possibly to meet with militants of the Maute group. A deadly firefight erupted when Hapilon's forces opened fire on the combined Army and police teams and called for reinforcements from the Maute group, an armed group that pledged allegiance to the Islamic State and which is believed to be responsible for the 2016 Davao City bombing, according to military spokesmen.

Maute group militants attacked Camp Ranao and occupied several buildings in the city, including Marawi City Hall, Mindanao State University, a hospital and the city jail. They also occupied the main street and set fire to Saint Mary's Cathedral, Ninoy Aquino School and Dansalan College, run by the United Church of Christ in the Philippines (UCCP). The militants also took a priest and several churchgoers hostage.

The Armed Forces of the Philippines stated that some of the terrorists were foreigners who had been in the country for a long time, offering support to the Maute group in Marawi. Their main objective was to raise an ISIL flag at the Lanao del Sur Provincial Capitol and declare a wilayat or provincial ISIL territory in Lanao del Sur.

On 17 October 2017, the day after the deaths of militant leaders Omar Maute and Isnilon Hapilon, President Duterte declared Marawi was "liberated from terrorist influence". Then on 23 October 2017, Defense Secretary Delfin Lorenzana announced that the five-month battle against the terrorists in Marawi had finally ended.

Background
The Maute group had established a stronghold in Lanao del Sur since February 2016 and was blamed for the 2016 Davao City bombing and two attacks in Butig, Lanao del Sur, a town located south of Marawi, in 2016. Since the militant group's founding in 2013, the Philippine government has downplayed the threat of ISIS in the Philippines. Following the February 2016 Butig clash with the Maute group, then-President Benigno Aquino III discounted the possibility of the Islamic State's presence in the country. He said that those behind the attack were just mercenaries wanting to be recognized by the Middle East-based terror group.

The Abu Sayyaf group, blamed for deadly bombings and kidnappings in the past, had also pledged allegiance to the Islamic State movement in the summer of 2014. One of its leaders, Isnilon Hapilon, was listed as among the world's most wanted terrorists by the US State Department with a reward of up to US$5 million for his capture. Following the abduction and subsequent beheading of Canadian businessman John Ridsdel in April 2016, Aquino disclosed that he had received death threats from the jihadist group, and that the Abu Sayyaf also plotted to kidnap his sister Kris, and Manny Pacquiao. Aquino also identified Hapilon behind attempts to convert and recruit inmates at the New Bilibid Prison to their cause, and embark on a bombing campaign in Metro Manila, which he said was "part of their effort to gain favor with ISIS."

In November 2016, President Rodrigo Duterte confirmed the Maute group's affiliation with the Islamic State although the Philippine military maintained that ISIL had not established links with militants in the Philippines. Amidst fierce fighting in Butig on 30 November 2016, Duterte, in a command briefing in Lanao del Sur, warned the Maute group: "Ayaw ko makipag-away sa inyo. Ayaw ko makipag-patayan, (I do not want a fight with you. I don't want us killing each other) but please, do not force my hand. I cannot be forever traveling here every month para lang makipag-usap (just to talk), at pagtalikod ko patayan nanaman (and when I turn around, there's killing again). I do not want to mention anything, but please do not force my hand into it."

On 2 December 2016, as the military regained control of Butig, the retreating Maute fighters reportedly left a note threatening to behead Duterte and the military. On 12 December 2016, in a speech before the Wallace Business Forum Dinner, Duterte dared the Maute group to attack Marawi, stating: "Because they (the Maute group) threatened to go down from the mountains to burn down Marawi? Go ahead, be my guest. We will wait for you there. Walang problema (No problem)."

From April to May 2017, Abu Sayyaf fought in clashes with Philippine security forces in Bohol which resulted in the deaths of three soldiers, a policeman and ten militants.

Prelude to the battle
The Armed Forces of the Philippines (AFP) stated that the fighting in Marawi was due to a raid conducted by the military in coordination with the Philippine National Police, contrary to earlier reports that the clash was initiated by the militant groups. Rolando Bautista, commanding general of the Philippine Army 1st Infantry Division, stated that they had received reports of impending activity two or three weeks ahead of time. As the combined military and local police team conducted zoning in Marawi to validate the information that suspicious personalities including Omar and Abdullah Maute were consolidating in the area, their team spotted instead Isnilon Hapilon. According to the Philippine military, Hapilon had been appointed as emir of the IS forces in the Philippines and was consolidating his group with the Maute and other terrorist groups. After residents of Marawi reported the presence of an armed group within their locale and after the AFP verified the information, the military launched a "surgical operation" to capture Hapilon.

23–27 May
Firefights between government forces and militants began at approximately 2:00 in the afternoon of 23 May 2017. The Peace and Conflict Journalism Network reported that the clash occurred in the Basak Malutlut area of the city as Hapilon's forces called for reinforcement from the Maute group. Maute fighters occupied the Amai Pakpak Hospital and ordered the PhilHealth employees out of the facility. The fighters allegedly replaced the Philippine flag hoisted in the hospital with the Black Standard used by the Islamic State group. A staff member of the hospital has later denied that this happened.
 * 23 May

The 103rd Brigade of the Philippine Army stationed at Camp Ranao was attacked by at least 500 Maute group militants. A number of militants were then seen waving their ISIS black flags as they roamed the streets of Marawi.

The whole city was put on lockdown as several buildings and houses were set ablaze by members of the Maute group. Dozens of gunmen occupied the Marawi City Hall as 107 inmates escaped from the Marawi City Jail and the Malabang District Jail 39 after the Maute attacks. Power and communication lines were also shut down due to the continued hostilities. Roads leading to Marawi were blocked by both government security forces and Maute militants.

Civilians were reported to have been abducted by the Maute group, including a priest and several parishioners of the Cathedral of Our Lady Help of Christians as the group demanded that the government stop its offensive against them.

The clashes sparked a mass evacuation of the city with residents fleeing by the thousands, causing traffic congestion on the highway to Iligan and Cagayan de Oro. At least eleven civilians have been killed in the ongoing firefight, two of which the Lanao del Sur Provincial Disaster Office identified as ambulance drivers who were stopped by Maute militants while responding to an emergency call. Nine of those civilians were on board a truck when they were stopped by Maute militants at a checkpoint and shot dead with their hands tied. A police officer was also reported to have been beheaded by the militants.

On 24 May, additional government forces arrived at the Laguindingan Airport as the military regained control of the Amai Pakpak Hospital. 120 civilians used as a human shield by the Maute group were rescued from the hospital. The Philippine military has also recaptured the city hall and the Mindanao State University.
 * 24 May

On 25 May, fresh fighting took place near the Lanao del Sur Provincial Capitol in the Marawi city center. Black-clad Maute and Abu Sayyaf militants were still spotted in the city's major roads and bridges. The militants also reportedly took control of the Lanao del Sur Electric Cooperative in Gadungan village. The AFP said there were still three or four dozen Maute, including Isnilon Hapilon, remaining in Marawi. The Philippine air force launched strikes against remnants of the group in three nearby villages.
 * 25 May

Reports came in that two Malaysian terrorists who were with Isnilon Hapilon in Marawi to push for the creation of the Islamic State in Southeast Asia were among those militants killed late Thursday. Intelligence sources also said that an Indonesian and a Saudi Arabian linked to ISIS were also killed in skirmishes in the city. The AFP said that 26 of the around 50 Maute in the area were killed and 30 government soldiers were wounded.

At a press briefing in Davao City, AFP Spokesperson Brig. Gen. Restituto Padilla stated that some of the terrorists are foreigners who have been in the country for quite some time, offering support to the Maute group in Marawi. He noted that of the twelve killed in a recent action, six were from out of the country.
 * 26 May

Amid continuing operations against the terror groups, several houses, including the residence of Lanao del Sur Representative Jun Papandayan, were seen burning as residents also reported seeing civilians killed after the military dropped bombs on Maute positions. Sources said the houses were targeted because of the presence of Maute snipers.

According to AFP Western Mindanao Command chief Lt. Gen. Carlito Galvez Jr., dwellings in the area were intentionally set on fire so as to keep them from being used as cover by the Maute. Limited air strikes were also used on Maute sniper positions. Galvez stated that no civilians were reported killed in the air strikes, and it was his hope they could keep military casualties low as well.

As of 26 May 2017, the priest Fr. Chito Suganob and his companions who were taken hostage by the Maute group on Day 1 of the clashes, were still being held by the group according to Marawi bishop Edwin de la Peña.


 * 27 May

1st Infantry Division spokesman Lt. Col. Jo-Ar Herrera told reporters: "We have identified where they are consolidating so we are doing surgical air strikes to destroy the local terrorist group." The military troops and Special Action Force continued on their clearing operations by checking each house and building in the city's downtown area. In the conduct of the operations on Saturday, troops have encountered child warriors as young as 10 years old armed with M-16 rifles being used by the Maute group.

By 27 May 90 percent of Marawi's population of more than 200,000 people has been evacuated to neutral grounds, particularly in Iligan.

28–31 May
The regional military spokesman Jo-Ar Herrera reported 19 civilians, some of whom were women and children, had been killed in Marawi by 27 May. Eight civilians had been found dead on the side of the road on the outskirts of Marawi on the previous Sunday (22 May). The victims were later identified as local carpenters who were part of an evacuation convoy; the militants stopped the convoy and then massacred those who could not recite verses from the Quran. A signed note was found attached to one of them, the author indicating that the victims had "betrayed their faith". Authorities said that 2,000 civilians were trapped in militant-controlled areas.
 * 28 May

Reports came in that 28 Malaysians had joined the Maute group. Citing intelligence sources in Manila, a Malaysian newspaper reported that the Malaysians arrived early last week supposedly for a religious event and may have also taken up arms, a conclusion they arrived at after 2 Malaysians were killed in firefights. The ongoing clash also raised concerns in Jakarta that extremist groups in Indonesia could be drawn to join the fight in Marawi as well.

Malacañang Palace Communications Secretary Martin Andanar appealed for foreign support in fighting the extremist groups in southern Philippines. In an interview with China Central Television, Andanar said "We need support, be that economic support, ideological support to fight the ISIS. Now, it is an international issue. We are doing our best to contain the ISIS and to stop it from spreading in the country."

The death toll in Marawi has reached 100, the Philippine military confirmed Monday, including 19 civilians and 61 militants. The military has also retaken most of Marawi previously occupied by the extremist groups. Presidential Spokesperson Ernesto Abella said Monday that only small areas in the city remained under militants' control. Also on Monday, the Philippine military reported that the Bangsamoro Islamic Freedom Fighters from neighboring Maguindanao have joined the Maute and Abu Sayyaf groups in Marawi and that the Abu Sayyaf leader Isnilon Hapilon remained holed up in the city.
 * 29 May

Amid continuing air strikes and as the militants fought government forces on 29 May, fourteen hostages managed to escape their Maute captors. The men said they were part of a group of 20 who had been taken captive on 27 May while evacuating the city. Their captors forced them to film a video appeal to Duterte to accede to the militants' demands or the hostages would be killed. One of the hostages was indeed beheaded, they reported, and one drowned during the escape.

A spokesman for Nur Misuari said Misuari ordered the Moro National Liberation Front to fight any Maute in Lanao del Sur. Misuari offered a unit of 500 to 700 MNLF fighters to help fight the extremists. Luis Jalandoni of the National Democratic Front stated his group was willing to help as well.

The Moro Islamic Liberation Front and the government decided to implement a "peace corridor" in Lanao del Sur as part of an effort to hasten humanitarian operations for displaced Marawi residents. The corridor spans from Marawi proper down to the Malabang town.


 * 30 May

In a video released on 30 May, abducted priest Fr. Teresito Soganub pleaded the government to stop their offensive against the militants and withdraw all their forces from Marawi and Lanao del Sur. Marawi Bishop Edwin dela Peña says that Soganub was relaying the Maute group's demands in exchange for the safety of Suganob and other people taken as hostages.

The Marawi city center remains under control of the Maute militants, as two of three bridges leading to the Marawi city center, the Mapandi and Bayabao bridges, still contained roadblocks and enemy vehicles with a black flag flying in front of them.

The Philippine Marines had been able to recover eighteen high-powered firearms, police and military uniforms, and black flags from their two-day clearing operations in Marawi. They also reported that eight terrorists had been killed Tuesday.

In a joint statement from the Philippine government and the Moro Islamic Liberation Front released Tuesday, Murad Ebrahim said the MILF welcomed the President's invitation for its forces to extend humanitarian assistance to civilians still trapped in Marawi.

AFP spokesperson Restituto Padilla said Wednesday that government forces have retaken 90 percent of Marawi, including parts of the city center and the two bridges that lead to it. According to Padilla, the surge in the number of militants might have something to do with the sympathizers they freed from the city jail, but that the military managed to secure all entry and exit points to prevent possible reinforcements for the militants.
 * 31 May

The Associated Press reported that eleven soldiers were killed and seven others were wounded by friendly fire in a military air strike as government security forces struggled to drive off remnants of the militant groups from the city. An AFP spokesman said the incident happened when a SIAI-Marchetti SF.260 turboprop aircraft providing close air support "over militant positions in Marawi" dropped a bomb that accidentally hit an army unit locked in close-range combat with the militants. Defense Secretary Delfin Lorenzana ordered an investigation on the incident.

At least eight militants have surrendered to government troops on Wednesday. According to AFP spokesman Restituto Padilla, the militants surrendered to the unit of Marine Task Force Tiger Tawitawi Commanding general Custodio Parcon and "have provided very, very valuable intelligence." It was the first time that members of the militant groups have surrendered since laying siege to Marawi on 23 May 2017. Additional marines and relief supplies arrived via transport ship on 31 May.

A friendly fire incident took place in Marawi. Two Philippine Air Force planes bombed rebel positions, but one plane missed its target and instead hit government troops on the ground, killing 10 soldiers. Following the incident, Senate President Aquilino Pimentel III asked for a review of the Philippine military's strategy in the ongoing campaign against the militant groups in Marawi. Senator Antonio Trillanes called the incident "tragic and unfortunate" as he called on the military to ensure that similar incidents will never happen again. Senator Panfilo Lacson encouraged the public to support the AFP as well as the investigation being conducted.


 * 2 June

Malacañang Palace spokesman Ernesto Abella dispelled speculations that the 2017 Resorts World Manila attack that transpired in the early hours of 2 June 2017 in Pasay was connected to the ongoing military offensive against the Maute group in Marawi or to ISIS. He also denied any possible terrorism link in the incident.

In an update to the media on the situation in Marawi, the AFP spokesperson said that the militants remained holed up in commercial buildings in the city center and that they believe Isnilon Hapilon to be still in Marawi. He also acknowledged that their earlier 2 June deadline for completely taking back the city from the militant groups won't be met as they continued to put up significant resistance. The Indonesian Foreign Ministry through its embassy in Manila was able to rescue 17 of their citizens from Marawi on Thursday with help from the AFP.

On 3 June 2017, Duterte and Nur Misuari (founding chairman of the Moro National Liberation Front) made an agreement that 2000 MNLF fighters would be enlisted into the Philippine military and join in the fighting in Marawi. However, a few days later, both the Armed Forces of the Philippines and Duterte himself issued statements that this would not be happening soon.

President Rodrigo Duterte said the Marawi crisis birthed a "newly evolving type of urban warfare" and his declaration of martial law in Mindanao is meant to fight this menace. In the full text of his letter to Congress released on that day, Duterte said this type of warfare is "characterized by the rebels' total disregard for civilian lives, cruelty to combatants and non-combatants alike, widespread looting, and pillaging of occupied communities."
