Scope of the mission

IGASOM was expected to eventually reach 8,000 troops, with an expected cost of $335 million for the first year. According to UN Security Council Resolution 1725, states bordering Somalia would not be eligible to deploy troops under IGASOM. The remaining (non-bordering) IGAD member nations include Sudan, Eritrea, and Uganda. Because of the objection of the burden falling on these three nations alone (and the rivalry between Ethiopia and Eritrea), the mission was expanded to include other member states of the African Union.

AMISOM has a different composition. As proposed, it comprised an initial three battalions, growing to a total of nine battalions of 850 troops each, which would serve for an initial stabilization period of six months. The mission was to be modelled after the African Union Mission in Burundi (AMIB).^[3]

ICU resistance

As early as 25 March 2005 Sheikh Hassan Dahir Aweys of the Union of Islamic Courts warned any peacekeepers would be unwelcome in the country. He was quoted by the BBC as saying, "We will fight fiercely to the death any intervention force that arrives in Somalia."^[20] Yet at the time, the ICU was not the political or military force it was to become later.

Faced with the ascendancy of the ICU after taking over the capital in the Second Battle of Mogadishu between May and June, 2006, UN-watchers were growing concerned with the level of hostility of the ICU towards the proposed IGASOM mission.^[13]

Though IGAD and the ICU met and published a cordial and formal communique^[21] committing the ICU to the IGAD plans on 2 December, by the time United Nations Security Council Resolution 1725 was passed on 6 December,^[11] the ICU was openly and militantly opposed to peacekeepers entering Somalia, and vowed to treat any peacekeepers as hostile forces. Because of regional divisions, there were also UIC resistance to allowing Ethiopian troops be part of the mission. Ethiopia, for its part, was leery of allowing Eritrean troops to be members of the IGAD peacekeeping force.

In the face of ICU threats, Uganda, the only IGAD members who had openly offered to send forces (a battalion), withdrew in the face of concerns of the present feasibility of the mission.^[22][23][24] In Uganda's defense, the crisis does not allow for peacekeepers when there are active hostilities conducted with heavy weapons (see Battle of Baidoa).

On 1 January 2007, after the defeat of the ICU in various battles in December 2006, Uganda again renewed its pledge of a battalion of troops. Between Uganda and Nigeria (which is a Member State of the African Union, but not of IGAD), there was a pledge of a total of 8,000 peacekeepers.^[25] Ghana, Rwanda and Tanzania were reported to be considering sending forces.^[26]

Gathering support

Following the defeat of the Islamic Courts Union in December 2006 – January 2007 the international community began to gather both fiscal commitments as well as military forces for the mission. Nations of the African Union (AU) outside the IGAD community were drawn on to provide support.

On 17 January 2007, the US ambassador to Kenya, Michael Ranneberger, said the US pledged $40 million to support the deployment of a peacekeeping force for Somalia.^[27] By 20 January, the European Union followed with a pledge of 15 million euros.^[28]

On 19 January 2007 the mission was formally defined and approved by the African Union at the 69th meeting of the Peace and Security Council.^[3]

On 22 January 2007 Malawi agreed to send a half-battalion to a battalion (ranging widely anywhere between approximately 400 to 1,200 troops) for a peacekeeping mission to Somalia.^[29]

On 24 January 2007 Nigeria pledged a battalion (a force between 770 and 1,100 troops) to join the Somali peacekeeping mission.^[30]

On 1 February 2007 Burundi committed to the peacekeeping mission, pledging up to 1,000 troops.^[31] By 27 March, it was confirmed that 1700 Burundian peacekeepers would be sent to Somalia.^[32]

On 2 February 2007, the United Nations Security Council welcomed the advent of the African Union and IGAD-led peacekeeping mission.^[33]

On 5 February 2007 Tanzania offered to train Somali government troops, but not to deploy peacekeepers.^[34]

On 9 February 2007 a gathering of 800 Somali demonstrators in north Mogadishu, where Islamist support was strongest, burned U.S., Ethiopian, and Ugandan flags in protest of the proposed peacekeeping mission. A masked representative of the resistance group, the Popular Resistance Movement in the Land of the Two Migrations, said Ethiopian troops would be attacked in their hotels; the same group had made a video warning peacekeepers to avoid coming to Somalia.^[35] By this date, Uganda, Nigeria, Ghana, Malawi and Burundi had committed to the peacekeeping mission, but the total force was about half of the proposed 8,000-strong force.^[36] Uganda had pledged 1,400 troops and some armored vehicles for a mission lasting up to 9 months, and the AU had pledged $11.6 million.^[37]

On 16 February 2007 Uganda announced it would deploy 1,500 well-seasoned troops as early as Saturday, 17 February 2007 under the command of Major General Levi Karuhanga. Reportedly the troops had been training for two years in preparation for the mission.^[38]

The Burundian troops were technically ready to go in early August 2007, but equipment promised by the United States and France had not yet arrived.^[39] On 23 December 2007, an advance force of 100 Burundians was deployed and another 100 soldiers arrived on 2007-12-24.^[40][41] By late 2008, 1,700 Burundian soldiers were deployed to Mogadishu.^[42]

On July 28, 2009, the World Health Organization was notified that 21 AMISOM soldiers in Mogadishu had become sick, and three had died, with acute peripheral edema, difficulty in breathing, palpitations, and fever.^[43] The WHO, together with the U.S. Center for Disease Control, AMISOM, and the Aga Khan University Hospital in Nairobi began an investigation. From April 26, 2009, to May 1, 2010, 241 AU soldiers had lower limb edema and at least one additional symptom; four patients died. At least 52 soldiers were airlifted to hospitals in Kenya and Uganda. Four of 31 hospitalized patients had right-sided heart failure with pulmonary hypertension. The illness was associated with exclusive consumption of food provided to troops (not eating locally acquired foods). Because the syndrome was clinically compatible with wet beriberi, thiamine was administered to affected soldiers, resulting in rapid and dramatic resolution.

Expanding role

In a closed door meeting in Kampala on 22 July 2010, AU ministers agreed to expand the mission's mandate from a peacekeeping focus to a peace-enforcement focus that would engage al-Shabaab more directly. The decision came soon after deadly bomb attacks in the Ugandan capital.^[44] A few days later in response to UN pressure, the AU agreed not to expand the mandate but did allow preemptive strikes against Al-Shabaab and promised more troops from other African countries.^[45]

On 23 July 2010, Djibouti and Guinea pledged troops to AMISOM.^[46] On 17 September 2010, an AU envoy said in Nairobi that AMISOM's size had grown from 6,300 to 7,200 troops after an additional battalion from Uganda joined the force.^[47] In December 2010, the UN backed AMISOM in increasing the mission's authorized size to 12,000 – UN Security Council resolution 1964 of 22 December 2010 – and at the same time reports indicated that Uganda had promised an extra 1,800 personnel, with Burundi an extra 850.^[48]

In March 2011 Burundi sent 1,000 extra soldiers to AMISOM, bringing the total number of Burundi troops deployed to 4,400.^[49] AFP, reported in Africa Research Bulletin, said Burundian military chief General Godefroid Niyombare said on 14 March 2011 the soldiers had been deployed a week before.^[50]

In February 2012, the U.N. Security Council boosted the number of troops deployed from 12,000 to 17,731. The approval comes after a series of recent successes against al-Shabaab fighters who had previous positions throughout the central and southern areas of the country.^[51] During the same month, AU Commander Fred Mugisha suggested that Al-Shabaab was "at [its] weakest" and would likely "implode in the not so distant future" owing to successive military defeats that it suffered as well as an exodus toward the Arabian Peninsula of hundreds of the group's fighters.^[52]

Due to the successful military operations against the Islamists, the United States has also been stepping up efforts to train and equip the AMISOM troops in a bid to stamp out the Al-Shabaab insurgency and limit its influence.^[53]

In October 2011, the Kenya Defence Forces began Operation Linda Nchi, crossing the border into Somalia to attack Al-Shabaab.^[54][55] On 12 November, the Kenyan government agreed to rehat its forces under AMISOM command,^[56] and later announced in March 2012 that it would send 5,000 troops to join AMISOM.^[56]

The East African reported in March 2012 on reorganisation of AMISOM's headquarters and sector commands. Personnel (J1) would be led by the AU, with Kenya taking responsibility for intelligence (J2) and logistics (J4), Uganda operations (J3) and engineer (J8), Burundi plans (J5) and communications/IS (J6), Sierra Leone training (J7), and Djibouti CIMIC (J9). There would also be four sectors: Uganda responsible for Sector One (the Shabelles and Banadir), Sector Two (the Jubbas) run by Kenya, Sector Three Burundi covering GEdo, Bay, and BAkool, and Sector from which Ethiopia forces were withdrawing from to be directed by Djibouti.^[57]

In November 2013, the Ethiopian government announced that it would integrate its troops that are deployed in Somalia into the AMISOM multinational force. Somalia's Foreign Minister Fowzia Haji Yussuf welcomed the decision, stating that the move would galvanize AMISOM's campaign against the insurgent group. She also emphasized the importance of collaboration between Somalia and Ethiopia.^[58] The Ethiopian authorities' announcement came a month after a failed October bombing attempt by Al-Shabaab in the Ethiopian capital of Addis Ababa, and a week after Ethiopia received a renewed terrorism threat from the insurgent group.^[59] According to Ethiopian Ministry of Foreign Affairs spokesperson Ambassador Dina Mufti, the Ethiopian military's decision to join AMISOM is intended to render the peacekeeping operation more secure.^[60] Analysts also suggested that the move was primarily motivated by financial considerations, with the Ethiopian forces' operational costs now slated to be under AMISOM's allowance budget. It is believed that the Ethiopian military's long experience in Somali territory, its equipment such as helicopters, and the potential for closer coordination will help the allied forces advance their territorial gains.^[61] On the other hand, there is a certain amount of unease following Ethiopia's entry into AMISOM given local animosity originating from Ethiopia's heavy handed intervention in 2006. There are also fears that Al Shabaab could use Somali animosity towards Ethiopia as a rallying cry and to recruit more members.^[62]

In December 2013, the U.S. government established a military coordination cell in Mogadishu at the request of AMISOM and the Somali government. The unit consists of a small team of fewer than five advisers, including planners and communicators between AMISOM and the Somali authorities. It is intended to provide consultative and planning support to the allied forces in order to enhance their capacity and to promote peace and security throughout the country and wider region.^[63]

From June 2021 to March 2022, the EU and its allies reimbursed Kenya nearly Sh2.54 billion, in quarterly disbursements Sh811 million, for its continued military participation in AMISOM. The funding had slowly been decreasing since it began in October 2011, with each soldier taking home only around USD $800 (Sh92,800) in this final installment.^[64]

Sectors

Extent of AMISOM forces in Somalia.

On 15 October 2011 Kenyan forces crossed the border into Somalia to attack al-Shebaab. Subsequently UN Security Council resolution 2036 of 22 February 2012 authorized an increase in AMISOM troop numbers to 17,731 to incorporate the Kenyans.^[109] This resolution took effect from mid-2012. At this time the initial Ugandan and Burundian AMISOM forces had been successful in largely clearing al-Shebaab militants from Mogadishu and the force was organized into new sectors.^[110]

• Sector 1 (headquartered in Mogadishu and predominantly the domain of the Ugandan Contingent) covered the Banadir, Middle Shabelle and Lower Shabelle regions.
• Sector 2 (headquartered in Kismayu and predominantly KDF responsibility, with the anticipated Sierra Leone contingent) covered the Gedo, Middle Juba and Lower Juba regions.
• Sector 3 (headquartered in Baidoa and predominantly the responsibility of the Burundian contingent) covering the Bay and Bakool regions.
• Sector 4 (headquartered in Belet Weyne and the responsibility of the Djiboutian contingent) covering the Hiraan region.

Later, UN Security Council resolution 2124 of 12 November 2013 authorized a troop increase to 22,126 through inclusion of an Ethiopian contingent.^[111] This took effect in January 2014, when the Sector organisation was modified to:^[112]

• Sector 1 (Mogadishu: Banadir and Lower Shabelle regions) – UPDF contingent
• Sector 2 (Dobhey: Lower and Middle Juba regions) – KDF contingent, with the Sierra Leone contingent operating in a 'Sector Kismayu' until these forces left. During January 2016 Ethiopian troops deployed to Kismayo.^[113]
• Sector 3 (Baidoa: Bay, Bakool and Gedo regions) – Ethiopian contingent
• Sector 4 (Belet Weyne: Hiiraan region) – Djiboutian contingent
• Sector 5 (Jowhar: Middle Shabelle region) – Burundi contingent

In January 2017 Kismayo was mentioned as a separate sector – Sector 6 – under Colonel Paul Njema.^[114] On 22 November 2017 AMISOM's twitter feed announced that Colonel Fréderic Ndayisaba of Burundi was replacing Colonel Paul K Njema of the Kenya Defence Forces (KDF) as Sector 6 Commander and described this command as a multinational sector composed of Burundian, Kenyan and Ethiopian troops based in Kismayo.

Civil staff

The civilian staff of AMISOM has been operating from Nairobi, Kenya since 2008 due to the security situation in Mogadishu.^[226] As of now, they number approximately 81 personnel.

Since the beginning of 2011 AMISOM and TFG has taken control over several strategic places in Mogadishu after several offensives against Al-Shabaab.

With the expanded control over the capital AMISOM on 16 May 2011 moved the civil staff and police officers to Mogadishu. This includes Special Representative of the Chairperson of the African Union Commission for Somalia (SRCC) Ambassador Boubacar Gaoussou Diarra and deputy (SRCC) Honourable Wafula Wamunyinyi.^[226]

Much of the key logistical support for the force was provided by the United Nations Support Office for AMISOM (UNSOA), a field mission of the UN Secretariat Department of Field Support.

The Civilian component was supervised by the Special Representative of the Chairperson of the African Union Commission for Somalia (SRCC) which was represented on the ground by Ambassador Mahamat Saleh Annadif. who oversees the Political, Civil, Humanitarian, Gender and Public Information departments.

Ambassador Epiphanie Kabushemeye-Ntamwana was the civilian Chief of Staff.

The Chief Administrative Officer Timothy Kiguti heads the support component of the mission which includes administration personnel, finance and budgeting, logistics and procurement among other issues.

The Police contingent, which provides capacity building, both institutional and individual in support of the Somali Police Force, was headed by the AMISOM Police Commissioner Anand Pillay.

* The reason why troops from Sierra Leone were withdrawn was the inability to rotate in fresh soldiers, due to the Ebola outbreak in Sierra Leone and the surrounding region. In response, Ethiopia has offered to replace the contingent from Sierra Leone with Ethiopian reinforcements.^[253]

- The total number of personnel under AMISOM (including armed personnel and civil staff) was reportedly around 22,126.^[84]

- Before joining AMISOM in January 2014, the Ethiopian Defense Force was believed to have an estimated 8,000 troops in the country.^[60] It is also believed that some Ethiopian troops in Somalia operate independently from AMISOM.^[254]

- Likewise, Kenya had troops deployed in Somalia independently before they were brought under the AMISOM umbrella

- Cameroon, Mali, Senegal, and Zambia were known to have a total of four personnel inserted into AMISOM. However, it is not known whether they were security or civil personnel.^[49][255]

- Furthermore, there are also a small number of police officers from Burundi, Gambia, and Zimbabwe that are inserted into AMISOM^[84]

March 2007 – February 2011

AMISOM medical facility records showed 110 Ugandan and 95 Burundian soldiers had died between March 2007 and February 2011 in Somalia. Another 798 AMISOM soldiers were wounded.^[234] Some of the deadliest incidents were:

• 23 February – 4 March 2011 – 53–82 AU troops were killed in clashes with al-Shabab fighters during an offensive in Mogadishu, 190 other AMISOM troops were also wounded.^[259] In addition, a Burundian soldier was captured alive by militants.^[238] These were, at the time, the heaviest losses since AMISOM deployed. 43 of those killed were confirmed as Burundian soldiers and 10 as Ugandans.^[259] Also, 110 of the wounded were Burundians. Beside the 43 killed in action, four Burundian soldiers were declared missing in action.^[237]
