Al-Shabaab (militant group)

• 1. Introduction

  ›

  Al-Shabaab, Arabic for "the youth", is a Sunni Islamist militant organization based in Somalia. On the 29th of October 2022, it claimed responsibility for a twin car bombing in Mogadishu that targeted the Ministry of Education. The attack killed 121 people and injured 333. It was the deadliest in the city since 2017.

  The group behind it began as a youth militia inside a larger movement. Today it controls territory in south and southwestern Somalia, which it calls the Islamic Wilayat of Somalia. It is allied with al-Qaeda, and it reaches into neighboring countries as well.

  How does a small militia become a force that can threaten a capital city? What does it believe, and who actually follows it? How does it pay for a war, run courts, broadcast on its own radio station and argue with a national army on social media? And why do analysts keep describing its story as a cycle of collapse and return?

• 2. The Youth Militia

  ›

  One account places the founding of Al-Shabaab in Las Anod in 2003, though the exact date remains unclear. That same year, the American Central Intelligence Agency began covert operations against the Islamic Courts Union. The Courts were an umbrella group that governed much of Somalia in practice. The CIA backed Somali warlords, hoping to prevent a "Taliban like" state that might shelter al-Qaeda.

  In 2005, Mogadishu was hit by a wave of unexplained assassinations and disappearances. The Islamic Courts claimed that covert American operations and the warlords were targeting their senior officials. The scholars C. Barnes and H. Hassan wrote that a military force called Al-Shabaab emerged in this context. They described it as related to the Courts movement but seemingly autonomous. Contrary to many reports, it was neither the Courts' armed wing nor their most important military component. Its fighters served as the youth wing of the Courts' militia. They earned a fierce reputation in the war against the CIA-backed warlord alliance in Mogadishu in early to mid 2006.

  Many early leaders and members had belonged not only to the Courts but also to al-Ittihad al-Islamiya. That older group was founded on Islamism and opposition to clannism. Several early leaders had also trained as mujahideen in Afghanistan, and they followed the Hanafi school of jurisprudence.

  Ethiopia launched a full-scale invasion of Somalia in December 2006, when Al-Shabaab numbered about six hundred fighters. The invasion killed many Courts affiliates and fractured the movement. That left a vacuum for the small youth militia. Over 2007 and 2008, Al-Shabaab established itself as an independent actor and a vehicle of armed resistance. Many Somalis saw it as a genuine resistance movement, despite its hardline readings of Islam. Thousands of new recruits joined.

  By 2008, the African Union put its strength at about 2,000 fighters, and the group began governing territory for the first time. In those early years, many Somalis found it disciplined, orderly and fair, which earned it real legitimacy. Arbitrary rulings later cost it that reputation. Violence and war crimes committed by Ethiopian troops pushed more people toward the group, and two years of fighting left it battle hardened.

  In May 2008, an American airstrike killed its military leader, Aden Hashi Ayro. Ahmed Godane rose to leadership in the aftermath and steered the organization in a far more violent direction. That alienated many fighters and civilian supporters, yet Ayro's death did nothing to stop the expansion. Ethiopian troops withdrew in January 2009, and public support for Al-Shabaab as a resistance faction fell sharply. The withdrawal came too late to undo what the occupation had built. Networks and territorial bases now stretched across the rural south-central regions.

• 3. Beliefs and Command

  ›

  According to the International Crisis Group, Salafism has been a core unifying principle of Al-Shabaab, though members and leaders do not interpret it the same way. Academics have also noted the influence of non-Salafi Sunni movements in Somalia. Officially, the group advocates a form of jihadism with transnational aims. It links local grievances to the plight of Muslims worldwide.

  The group denounced the 2006 Ethiopian invasion as "Zionist-Crusader aggression". It claimed the United States had "unleashed its 'hunting dogs' in Ethiopia and Kenya". Yet this global framing is not universal inside the movement. Much of its Somali support base wants a stable Islamic state inside Somalia. The more ambitious want a Greater Somalia that unites ethnic Somalis in Ethiopia, Kenya and Djibouti. Other supporters care mainly about clan and local goals, and they are prone to infighting and shifting alliances.

  What holds these camps together is a shared set of enemies. They oppose outside intervention in Somalia, and they reject the internationally recognised Federal Government because it has no basis in Sharia law. Al-Shabaab declares takfir against that government and justifies attacks on its officials and civilian supporters. Its hardliners follow a Takfiri reading of al-wala' wal-bara', a principle of loyalty and disavowal that calls for distance from non-Muslims and those seen as apostates.

  In 2009, the group destroyed a Sufi shrine and its graves, arguing that elaborate burial sites conflict with Sharia. It has clashed with Ahlu Sunna Waljama'a, a Sufi militia that backed the African Union mission. It has persecuted Somalia's small Christian minority, accusing them of helping foreign "Crusaders" convert Somalis. After the 2019 DusitD2 complex attack, it said the assault was retaliation for the declaration of Jerusalem as Israel's capital.

  At the top sits an executive tanfid council of 7 to 14 members, supported by a consultative shura. Departments called makhtab cover the military, explosives, preaching, taxation, local administration, Islamic courts, intelligence and a police force known as Jaysh al-Hisbah. Ten governors, called waali, oversee civil services such as welfare and roads in areas the group holds.

  In a 2018 analysis, the Somali Hiraal Institute found that five of the ten executive shura members were from the Hawiye clan. So were about 94 of the top 220 officials. Even so, the group officially opposes clannism and has tried to appoint leaders from many clans and ethnic groups. Rank-and-file members are sometimes recruited by force. Others are drawn by regular pay and political propaganda, and many are children.

  In February 2012, an officer named Fu'ad Qalaf urged a Somali gathering to send unmarried daughters to fight, although the group had used only male fighters until then. The International Crisis Group reports that women rarely fight directly. They do play roles in recruitment, intelligence and the smuggling of explosives.

  Estimates of the group's size swing widely. Observers put it at 7,000 to 9,000 fighters in 2017. In 2018, the Council on Foreign Relations estimated 3,000 to 6,000, and the United States military estimated 4,000 to 6,000. In 2020, the United States Africa Command estimated 5,000 to 10,000. A United Nations expert report in February 2022 raised the figure to 7,000 to 12,000, and by late 2022 President Hassan Sheikh Mohamud was speaking of 15,000 to 18,000. That climb followed years in which the group had lost its largest cities.

• 4. Fracture and Purge

  ›

  By 2009 and 2010, Al-Shabaab controlled most of central and southern Somalia, everything south of the semi-autonomous region of Puntland. It had built administrative structures to govern the land it held. It was especially good at winning over local leaders and building cross-clan coalitions. It paired its principled opposition to clannism with what analysts call "pragmatic clannism", a willingness to manipulate clan networks and exploit rivalries between clans.

  Around 2009, kidnappings and bombings in urban areas grew sharply, and the Somali diaspora's support dwindled in response. In late 2009, after the Ethiopian departure, several leaders defected to the Somali government. They cited suicide attacks, executions, extortion, the group's treatment of foreign humanitarian aid, and what they called its "false interpretations of Islam".

  The military tide turned with the failure of the August 2010 Ramadan offensive, which opened the Battle of Mogadishu and cost the group heavily. By August 2011, it announced a "strategic withdrawal" from the capital. From the outskirts it kept up guerrilla attacks on African Union forces and the transitional government. In October and November 2011, Kenya and Ethiopia launched offensives with local militias. Kenya's Operation Linda Nchi pushed from the south while Ethiopia advanced from the west. Baidoa fell to Ethiopia in February 2012. Kismayo, a port city and revenue hub, fell to Kenya in October 2012.

  Inside the group, some members considered the Ramadan offensive disastrously ill-conceived. Anger focused on Ahmed Abdi Godane, who had been publicly named emir in December 2007. A severe drought was gripping the region, and critics around Hassan Dahir Aweys and Mukhtar Robow opposed the group's response to the famine, especially its obstruction of foreign aid. They argued that authoritarian rule and violence were costing public support. Some blamed Godane's lack of clan roots, saying it led him to undervalue the lives of civilians and fighters alike.

  On the 9th of February 2012, Godane appeared in a fifteen-minute video and pledged allegiance to al-Qaeda and its leader Ayman al-Zawahiri. Zawahiri confirmed the alliance, saying it would "please the believers and disturb the disbelievers". Other senior figures met at a conference in Baidabo and rejected Godane's proposal to rename the group Al-Qaeda in East Africa. They resolved to focus on domestic issues rather than global jihad, and to create a regional shura of clerics independent of al-Qaeda. Aweys said publicly that the group and al-Qaeda were "merely a small part of the larger Islamic group" and that al-Qaeda's ideology should not be seen as the only righteous path.

  In June 2013, Godane's critics paid for the argument. Ibrahim al-Afghani and three other senior commanders were executed that month, in what was virtually a purge. Omar Hammami was killed in September. Aweys fled the group in mid-2013.

  Defections ran alongside the purges. In June 2012, the Somali government said around 500 militants had already defected, with more arriving every day. On the 5th of September 2012 and again on the 22nd, about 200 fighters surrendered each time, at Afmadow and then Garsale. Godane had won the leadership struggle, but a drone would reach him the following year.

• 5. Resurgence

  ›

  On the 1st of September 2014, an American drone strike killed Godane. Ahmad Diri took office as emir the same week. That year and the next, Operation Indian Ocean, a joint effort of the African Union mission, the Somali government and the United States, added to the group's losses. In October 2014, the Somali government claimed that over 700 militants had surrendered since it offered an amnesty in September. Other senior members died in clashes or drone strikes in 2014 and 2015. According to some reports, the group has since weighted local grievances above global jihad.

  After its withdrawal from Mogadishu, the group had returned to asymmetric warfare. Aweys announced the shift in a media interview shortly after that withdrawal. The group avoided large battles, preferring smaller ambushes at places of its own choosing. It also cultivated what analysts call a "semi-territorial presence". It no longer held exclusive military authority over large areas, but it kept a sporadic presence, and real influence, in key regions and parts of key cities.

  Some of its deadliest strikes came outside Somalia. Four militants attacked the Westgate shopping mall in Nairobi in September 2013 and killed 67 people, the deadliest attack in Kenya since the 1998 embassy bombings. The journalist Simon Tisdall read it as a reflection of the internal power struggle, with Godane's hardline faction asserting authority. Two years later, 148 people died at Garissa University College in an attack that targeted Christian students.

  In 2016, two sophisticated attempts to bring down airliners surfaced. In February, a device hidden in a laptop bag that had passed screening exploded mid-flight and killed only the bomber. In March, another laptop bomb went off during screening. The United Nations Security Council later prohibited the transfer of bomb components to Somalia.

  In October 2017, a suicide truck bombing in Mogadishu killed more than 500 people, many of them children. The group did not claim it but was suspected of involvement. Another suicide truck bomb in December 2019 opened a series of attacks on the capital that lasted into 2022. In January 2020, it attacked a Kenyan base to target American military personnel. By then it operated freely across much of rural Somalia, with its main base in the Jubba River Valley. It had also expanded into Puntland, prompting an offensive by Puntland forces in 2021. By July 2022, it was generally considered resurgent. That was partly enabled by fewer American air strikes, and possibly spurred by competition with Islamic State in Somalia.

  On the 20th of July 2022, Al-Shabaab invaded Ethiopia's Somali Region, taking advantage of the ongoing Tigray War. More than a thousand fighters staged diversionary attacks on four border towns. That let a force of 500 to 800 fighters push through the Ethiopian security zone and advance 150 km into the region. After two weeks of clashes and airstrikes, Ethiopian federal and regional forces began reasserting control. A battalion of around 500 fighters slipped past them and reached its main target, the Bale Mountains.

  In August 2022, President Hassan Sheikh Mohamud declared "total war" in a televised address after a deadly hotel attack in Mogadishu. By September, Somali and African Union offensive operations, backed by American airstrikes, had reached their highest intensity in five years. They focused on the central Hiraan region. On the 20th of September 2022, the Ministry of Information said the president would offer Al-Shabaab members no option other than surrender.

  On the 26th of May 2023, the group claimed an attack on the Buulo Mareer base, about 75 miles southwest of Mogadishu, that it said killed 137 soldiers. Ugandan President Yoweri Museveni said the number was closer to 54 African Union peacekeepers. In December 2024, the UN Security Council approved a new mission, AUSSOM, to deploy up to 12,626 personnel. Two weeks later, on the 26th of December, the group confirmed that senior leader Mohamed Mire Jama died in an American drone strike near Kunyo Barrow in the Lower Shabelle region.

  In early 2025, Al-Shabaab launched its most ambitious offensive in years and captured dozens of towns. Its ultimate objective is to seize Mogadishu and overthrow the federal government. By April, rumors of an assault on the capital were spreading on social media. That did not happen, but the motorcade of President Hassan Sheikh Mohamud was attacked as it drove through the city. International airstrikes and local counterattacks have slowed the advance.

  According to The Telegraph, the group is also pursuing a "hearts and minds" strategy to shed its reputation for repression. Large indiscriminate suicide attacks in Mogadishu have largely ceased. Analysts compare the campaign to the Taliban's 2021 offensive in Afghanistan. They note that the Somali and Afghan governments have both been described as products of the war on terror, marked by corruption and low public legitimacy.

• 6. Rule and Relief

  ›

  Somalis have been seen traveling out of government-held areas into Al-Shabaab territory to settle disputes, especially ones involving clan dynamics. They do so because they distrust official institutions. Where it rules, the group keeps what observers call "limited but effective" administrative control. It provides Sharia-based courts that are sometimes compared favorably with government services. In early 2010, Somalia had an excellent crop yield, and the group claimed credit. It said it had reduced food imports and redistributed income to poor rural farmers. The group has also been accused of widespread human rights abuses, including a brutal application of hudud punishments.

  Aid agencies face a harsher picture. The group routinely expels, attacks and harasses aid workers, yet it lets some agencies operate. At the height of its control it ran a system to regulate, tax and watch them. It often wants to coopt aid for its own political and material benefit. Senior agency representatives strongly rejected claims of talks with the group, while workers on the ground reported negotiating directly out of necessity.

  The journalist Jon Lee Anderson wrote that the number of Somalis dependent on international food aid had tripled since 2007, to an estimated 3.6 million. He reported that forty-two local relief workers had been killed in two years. In 2009, Godane banned the UN World Food Programme and Western agencies. Robow and Aweys opposed the ban, but Godane overruled them.

  In July 2011, as the Eastern Africa drought deepened, the group said it had lifted restrictions on international humanitarian workers. Yet its members dismissed the UN's famine declaration as grossly exaggerated and barred some organizations from affected regions. In some cases, relief supplies were used as bribes to recruit fighters, after casualties and defections had thinned its ranks. In August 2011, Prime Minister Abdiweli Mohamed Ali announced a new 300-man security force to protect aid convoys and displacement camps. Access improved, and a scaling up of relief in mid-November led the UN to downgrade several regions from famine to emergency levels.

  Governance has sometimes taken unexpected turns. When COVID-19 arrived, Al-Shabaab acknowledged the pandemic and formed a prevention and treatment committee. In mid-June 2020, it announced a coronavirus treatment centre in Jilib, about 380 km south of Mogadishu.

  In July 2018, it announced a complete ban on single-use plastic bags, saying they "pose a serious threat to the well-being of humans and animals alike". The same broadcast banned the logging of several rare tree species. Some observers welcomed the environmental steps but said they were overshadowed by the group's terrorism. Others mocked the United States and other countries for doing less on climate change than a terrorist group.

• 7. Voice and Recruits

  ›

  Radio Andalus is the group's own station, broadcasting in Somali, Arabic, Swahili and English. It runs mostly on relay stations and equipment seized from private broadcasters, including the BBC. In April 2010, Al-Shabaab banned BBC and Voice of America broadcasts on Somali radio, objecting to what it called Christian propaganda. In 2010 it also launched a television news channel, al-Kataib News, before being expelled from Mogadishu the next year. In rural areas, most contact is face to face, through seminars on Islamic jurisprudence and community meetings about grain and livestock distribution. The group also stages military parades as a show of force.

  Its media wing, the al-Kataib Media Foundation, has made propaganda films since early in the campaign against Ethiopian forces. Since 2009 they have become more professional, reportedly with direct help from al-Qaeda's As-Sahab Media Foundation. Early films circulated online as recruitment tools, particularly for foreign jihadists. Later ones show the group handing out humanitarian aid and joining community activities. Others are gruesome, displaying the bodies of beheaded members accused of spying. Some try to mobilize attacks abroad. An October 2013 film urged British jihadists to follow Lee Rigby's killers. A February 2015 film called for attacks on shopping malls in Canada, the United Kingdom and the United States, naming the West Edmonton Mall in Alberta and the Mall of America in Bloomington, Minnesota.

  Al-Shabaab was an early adopter of the internet among African insurgents. American-born Omar Shafik Hammami, also known as Abu Mansoor al-Amriki, kept a video blog about life in the group for many years. From 2009 he also posted raps about jihad. The group's official website closed in 2009, and it has since relied on sympathetic sites and, more commonly, social media. It has used Facebook to reach the Somali diaspora, and it has used Twitter prolifically since late 2011.

  During Kenya's offensive in 2011 and 2012, the group tweeted under the handle @HSMPress to urge Somalis to fight Kenyan forces and to recast its losses as tactical retreats. Most attention went to its exchanges with Major Emmanuel Chirchir, then spokesman for the Kenya Defence Forces. When Chirchir said Kismayo had been captured, the group tweeted that the soldiers were "a grotesque parody of an army" and that its fighters could "outpace ur world-class runners by far". It added that they "Run like a Kenyan". It even suggested meeting a UN official for "a caramel macchiato". Chirchir himself argued that closing the account would be counterproductive, because "Al-Shabaab needs to be engaged positively, and Twitter is the only avenue."

  Twitter suspended the English-language account in January 2013, apparently after death threats against Kenyan hostages and the French spy Denis Allex. A second account opened in February 2013 and was closed in September. The group relaunched an English account on the 11th of September 2013. Two weeks later, it live-tweeted the Westgate attack, with at least eight affiliated accounts active over several days. The main account had 15,000 or more followers and was retweeted several million times before it was shut down.

  Foreign fighters have been central to this story. In 2010, there were an estimated 200 to 300 foreign fighters, plus a further 1,000 ethnic Somalis from the diaspora. That year, the former head of MI5, Jonathan Evans, told a London security conference that "a significant number of U.K. residents" were training with the group. Estimates of British recruits ranged from 50 to 100. In 2011, a House committee reported that more than 40 Muslim Americans and 20 Canadians had fought with the group, and that at least 15 had been killed. Two Somali Americans in Minnesota were convicted that year of illegally financing it.

  Non-Somali fighters have organised high-profile attacks, including the 2010 Kampala bombings. Their larger value lay in combat experience, which has been linked to better explosives, sharper sniping and more suicide attacks. Early Western recruits helped produce the first English-language propaganda, and Swahili is still the second most common language in its publications. The group deliberately highlights the diversity of its recruits as proof that it rises above clannism and nationalism.

  Foreign recruitment peaked between 2011 and 2013 and then faded. The Syrian civil war became the focus for jihadist recruiting networks. Godane also blamed foreigners for the group's disunity and executed several during his 2013 purge. As the group turned to local governance and clan politics, foreigners, often mistrusted by locals, lost influence. By 2020, estimates of foreign recruits still active ranged from 450 to 2,000, mostly from Kenya, Tanzania and Uganda.

• 8. Money and Allies

  ›

  In 2020, the Hiraal Institute estimated that Al-Shabaab collected at least $15 million every month, a scale similar to the government's own revenue. The UN put its military budget at about $21 million in 2019. After 2014, the group set up its own Ministry of Finance. It rotates among revenue streams as its military and political fortunes change.

  At first, much money came from the Somali diaspora and international jihadists. The weak financial regulation of the Somali government and widespread use of the hawala remittance system made that easy. Osama bin Laden publicly called on Muslims to send money to the group. Diaspora giving declined after the Ethiopian withdrawal as its reputation for brutality grew. Counter-terrorism efforts by foreign governments have since obstructed international funding.

  Charcoal smuggling through Kismayo became a major source of income once the group controlled Somali port cities. The UN calculated that illegal trade brought in between $15 million and $50 million a year, and it banned Somali charcoal imports. The group also profits from smuggling and taxing ivory, sugar and, reportedly, heroin, and it has been tied to illegal mining. In 2011, Colonel John Steed of the UN's counter-piracy division warned of circumstantial evidence that the group was seeking to cooperate with pirate gangs. Other reports said members had extorted pirates for protection money equal to 20 percent of ransom proceeds.

  Between 2008 and 2011, the group built a sophisticated tax system framed as zakat but often resembling extortion. It reaches clans, traders, corporations, farmers and herders, and livestock are sometimes stolen outright as pre-emptive taxation. Aid agencies are taxed in return for permission to operate. After losing urban areas, the group leaned harder on zakat. Its intelligence services let it tax areas outside its control. According to the Hiraal Institute, more than half of its 2019-20 revenue came from Mogadishu, where major companies are taxed at 2.5 percent of annual profits. A Somali army commander even admitted paying. Those who refuse have been punished harshly, including by blockading villages under threat of starvation.

  Puntland is a key transit point for weapons arriving in Somalia. Small arms and ammunition come most often from Yemen, crossing the Gulf of Aden in skiffs. Occasional larger shipments come from the Makran coast of Iran. Government weapons also leak to the group. UN expert reports in 2018 and 2019 found that state military equipment reaches the black market, where some is sold to the group. In some cases, senior officials orchestrate large diversions, and in others, low-ranking soldiers sell weapons to survive. The group has also infiltrated state institutions. On the 24th of July 2019, regional government employees carried out a bombing in Mogadishu that killed Mayor Abdirahmean Omar Osman.

  Eritrea was long suspected of arming the group. In December 2009, UN Security Council Resolution 1907 imposed sanctions on Eritrea for allegedly arming and financing militias in southern Somalia. A UN monitoring group alleged in 2011 that Eritrea gave about $80,000 a month and made two air deliveries of weapons. Eritrea called the accusations "concocted, baseless and unfounded". The International Crisis Group suggested earlier Eritrean support had aimed at undermining Ethiopia, and that Hizbul Islam was a likelier recipient. After later reports found no evidence of direct support, the Security Council lifted the sanctions in November 2018.

  The courtship with al-Qaeda began long before the pledge. The academic Daniel Byman calls the earlier relationship "on-again, off-again". Al-Shabaab sometimes sheltered al-Qaeda leaders in exchange for technical help. In September 2009, a video titled "At Your Service Osama" declared allegiance to bin Laden, an "unrequited courtship" largely ignored by al-Qaeda. After the alliance became official, a corps of al-Qaeda-trained militants moved to Somalia to teach infantry skills, explosives and assassination. Even so, Al-Shabaab stayed largely independent. A 2021 statistical analysis found no significant effect on its military strategy.

  Other unions were shakier. Hizbul Islam, a smaller Somali militant group, was absorbed in December 2010 after military defeats. On the 24th of September 2012, it split away, calling the union nominal. In Kenya, the group has used al-Hijra as its official wing since 2012. In 2013, it created Jaysh Ayman, based mainly in the Boni Forest, which proved more effective. Links to al-Qaeda in the Arabian Peninsula may matter most. Analyst Katherine Zimmerman told the US Congress that it "almost certainly provided the equipment or the expertise" for the 2016 laptop bomb. In June 2012, General Carter Ham said the group, al-Qaeda in the Islamic Maghreb and Boko Haram were trying to coordinate funding, training and explosives.

  In early 2015, the Islamic State of Iraq and the Levant began releasing videos urging Al-Shabaab to switch allegiance. The group publicly ignored them. By September 2015, an internal memo reaffirmed loyalty to al-Qaeda and banned any discussion of the rival. In October 2015, the senior commander Abdul Qadir Mumin and about 20 followers in Puntland pledged to ISIL. The head of the Lower Shabelle region, Abu Abdalla, warned that pro-ISIL members should leave or be killed. Fighting flared again in 2018, when the spokesman announced Operation Disease Eradication. The general command also released an 8-page treatise rebuking ISIS.

  On the 7th of June 2012, the US State Department offered $33 million in bounties for seven senior commanders, including $7 million for Godane. In reply, Fu'ad Qalaf offered ten camels for information on President Barack Obama. He offered ten cocks and ten hens for information on Secretary of State Hillary Clinton. The American envoy Johnnie Carson dismissed the counter-offer as "absurd".
