Yemeni Civil War
The Yemeni civil war is an ongoing multilateral civil war that began in late 2014 mainly between the Rashad al-Alimi-led Presidential Leadership Council and the Mahdi al-Mashat-led Supreme Political Council, along with their supporters and allies. Both sides claim to constitute the official government of Yemen.

Causes#
The proximate trigger for the Yemeni Civil War was the Houthi movement's seizure of the capital Sana'a in September 2014 and the subsequent forced resignation of President Abd Rabbuh Mansur Hadi in January 2015[1]. When Hadi escaped to Aden and repudiated his resignation, the country split between rival administrations, drawing in regional powers and precipitating the Saudi-led intervention that began in March 2015. The armed confrontation was, however, the culmination of structural failures that had been accumulating across decades of Yemeni state-building.
The political foundation of the conflict lay in the incomplete and deeply contested unification of North and South Yemen in 1990. The merger concentrated power in the northern highland elite centered on Sana'a, while southerners experienced marginalization in the security services, civil administration, and land tenure. Southern grievances coalesced into the Hirak separatist movement after 2007, a movement whose unresolved demands remained a destabilizing current running beneath the nominal unity of the state[1]. At the same time, the Houthi insurgency in the Saada governorate — rooted in Zaydi Shia identity politics and resistance to the perceived encroachment of Salafi movements backed by Saudi Arabia — had fought six separate rounds of conflict with the central government between 2004 and 2010, none of which produced a durable settlement.
The 2011 Arab Spring protests accelerated the collapse of the Ali Abdullah Saleh patronage network that had long managed, rather than resolved, these tensions. Saleh's resignation under Gulf Cooperation Council mediation transferred nominal authority to Hadi but left intact the factional military structures, tribal alliances, and parallel patronage channels through which Saleh continued to operate[1]. The National Dialogue Conference of 2013–2014, convened to draft a post-transition political framework, produced a federal reorganization plan that the Houthis rejected as gerrymandering designed to confine them to a landlocked northern region. Saleh's subsequent tactical alliance with the Houthis — bringing his residual military loyalists into alignment with the movement he had fought for nearly a decade — gave the insurgency the organizational capacity to take Sana'a and then advance southward.
Economic deterioration compounded every political cleavage. Yemen was already the Arab world's poorest state, with dwindling oil revenues, severe water scarcity, high unemployment among a rapidly growing population, and a fiscal structure almost entirely dependent on hydrocarbons whose production was in visible long-term decline[1]. The transitional government's inability to deliver services or payroll eroded whatever legitimacy the post-Saleh order might have claimed. Al-Qaeda in the Arabian Peninsula, exploiting the security vacuum in the south and east, added a further dimension to the crisis, ensuring that the conflict would attract the sustained attention — and intervention — of outside powers for whom counterterrorism objectives overlapped uneasily with support for any particular Yemeni faction.
Geopolitically, the war became a theater for the broader Saudi–Iranian rivalry almost immediately. Riyadh framed the Houthi advance as an expression of Iranian expansionism analogous to Tehran's influence in Iraq, Syria, and Lebanon, a characterization that shaped the political justification for the coalition military campaign[1]. Iranian material and advisory support for the Houthis, while disputed in its precise extent, provided the movement with ballistic missile and drone capabilities that would carry the conflict well beyond Yemen's borders — including strikes on Saudi territory and, ultimately, the 2022 Abu Dhabi attack that demonstrated the war's regional reach. The conflict thus fused domestic state failure with a transnational sectarian-geopolitical contest, a combination that has made negotiated resolution consistently elusive.
Consequences#
The Yemeni civil war, which escalated sharply after Houthi forces seized Sana'a in late 2014 and has continued without a comprehensive peace settlement, has produced one of the most severe humanitarian catastrophes of the twenty-first century. No formal treaty has ended the conflict; a UN-brokered truce agreed in April 2022 provided a partial and fragile reduction in hostilities, but it lapsed without being converted into a durable ceasefire, leaving Yemen in a condition of frozen, low-intensity warfare punctuated by periodic escalation[1]. The absence of any recognized final settlement means that the formal consequences of the war remain structurally incomplete, yet the cumulative damage to Yemen's political order, infrastructure, and population has already proved irreversible in several respects.
The humanitarian toll is the war's most quantifiable consequence. The United Nations has described Yemen as one of the world's worst humanitarian crises, with estimates of deaths — from combat, disease, and famine combined — exceeding 150,000 by the early 2020s and displacement figures surpassing four million[1]. The Battle of Al Hudaydah in 2018 severely damaged the port through which the majority of Yemen's food imports entered the country, compounding pre-existing famine conditions. Cholera outbreaks of a scale rarely seen in the modern era followed the destruction of water and sanitation infrastructure, and the health system effectively ceased to function across large portions of the country.
Geopolitically, the conflict entrenched a Saudi–Iranian proxy competition that has reshaped the Arabian Peninsula's security architecture. The Saudi-led military intervention, which began in March 2015, drew the Gulf Cooperation Council states into a prolonged and costly war that produced no decisive military outcome. Houthi missile and drone strikes reached deep into Saudi territory and, in the 2022 Abu Dhabi attack, struck the United Arab Emirates, demonstrating that non-state actors armed by Iran could project force across the region. Saudi Arabia's willingness to negotiate directly with the Houthis by 2023 represented a significant recalibration of its Yemen policy, one driven partly by war fatigue and partly by the broader Saudi–Iranian diplomatic normalization facilitated by China[1].
Territorially and politically, the war has fragmented Yemen in ways that a future peace agreement will struggle to reverse. The 2015 battle for Aden established the southern port city as the seat of the internationally recognized government, but the 2019 clashes in southern Yemen between that government and the Southern Transitional Council — a separatist movement backed by the UAE — revealed that the anti-Houthi coalition was itself fractured along lines of Yemeni political geography that predate the current war. The formation of the Presidential Leadership Council in 2022 was an attempt to paper over these divisions, but southern separatism, tribal fragmentation, and the autonomous presence of al-Qaeda in the Arabian Peninsula in areas such as Al Mukalla all persist as structural challenges to any reunified Yemeni state[1].
What the war has not resolved — and what any eventual settlement will inherit — is the underlying question of state legitimacy and resource distribution that drove the conflict's initial phase. Yemen was already the poorest country in the Arab world before 2014; the destruction of what limited institutional capacity it possessed has deepened dependency on external aid and remittances to a degree that makes reconstruction contingent on sustained international financing for which no credible mechanism yet exists. The Red Sea crisis that erupted in late 2023, as Houthi forces targeted international shipping in solidarity with Gaza, demonstrated that the war's consequences had extended well beyond Yemen's borders, disrupting global trade routes and drawing in Western naval responses — a reminder that the conflict's regional and international dimensions remain active even as its internal front lines have partially stabilized[1].

17 catalogued engagements
- Battle of Aden (2015)
July 22, 2015
The Battle of Aden was a nearly four-month contest for control of Yemen's southern port city, pitting Houthi rebels and Yemen Army forces loyal to former president Ali Abdullah Saleh against units loyal to President Abdrabbuh Mansur Hadi alongside Southern Movement militias. As the primary southern urban center and site of Hadi's government-in-exile, Aden held both symbolic and strategic weight within the broader Yemeni Civil War. The battle drew in a wide array of commanders on both sides, reflecting the fractured loyalties that defined the conflict, including the split within the Yemeni military between Houthi-aligned Saleh factions and pro-Hadi forces. The outcome of the fighting shaped the territorial balance between the Houthi-Saleh bloc, which had swept southward after consolidating control in Sanaa, and the coalition backing Hadi's internationally recognized government, including Gulf Cooperation Council states under Saudi leadership.
- Battle of Al Mukalla
April 16, 2015
- Battle of Dhale
May 26, 2015
The Battle of Dhale was a contest for control of Dhale city and its surrounding area during the broader Yemeni Civil War of 2014. The engagement pitted Houthi forces and Yemen Army units loyal to former president Ali Abdullah Saleh against militiamen and Yemen Army units aligned with the internationally recognized government of Abd Rabbuh Mansur Hadi. Control of Dhale held operational relevance within the wider conflict, as both coalitions sought to consolidate territorial footholds across Yemen during the 2015 phase of the war when front lines were actively shifting. The battle reflected the fractured nature of Yemeni military loyalty, with regular army units split between the two competing governments and fighting on opposing sides.
- Battle of Nihm
December 16, 2015
The Nihm Offensive, beginning in mid-December 2015, marked a coordinated push by Hadi government forces into the District of Nihm, a strategically positioned area bordering Al-Jawf and Marib governorates. The seizure of Mas camp and, within days, the 312th and 334th Armored Brigade camps represented a significant territorial advance along axes linking two key governorates. Houthi and allied forces mounted fierce resistance that prolonged the fighting into February 2016, when government forces finally consolidated control of the 312th Armored Corps camp. The operation demonstrated the government's capacity to conduct a multi-axis offensive drawing forces from both Marib and Al-Jawf, though the protracted resistance underscored the difficulty of dislodging entrenched Houthi positions even when outnumbered or outmaneuvered at the operational level.
- Battle of Port Midi
December 19, 2015
The Battle of Port Midi was an engagement during the Yemeni Civil War in which Saudi coalition-backed Hadi loyalists seized the port of Midi from Houthi forces. Despite the loyalist capture of the port, Houthi fighters and allied popular committees continued to conduct attacks in the surrounding area, limiting the practical consolidation of the gain. Fighting spread beyond the port itself into the broader Hajjah Governorate, reflecting the decentralized and contested nature of the conflict along this front. Over a year after the initial battle, Hadi loyalists extended their control to Harad District in Hajjah Governorate, suggesting the engagement at Port Midi was part of a longer, incremental loyalist effort to secure the northwestern corridor rather than a decisive shift in the campaign.
- Saudi-led intervention in the Yemeni civil war
March 25, 2015
On 26 March 2015, Saudi Arabia led a coalition of nine countries from West Asia and North Africa in a military intervention in Yemen, acting at the request of President Abdrabbuh Mansur Hadi after Houthi insurgents seized the capital, Sanaa, in September 2014. UN-mediated efforts to establish a power-sharing transitional government had collapsed, and Hadi fled to Saudi Arabia shortly before the intervention began. The operation marked a significant escalation of the Yemeni civil war, internationalizing a conflict that had until then been primarily internal. With force sizes on both sides estimated in the range of 150,000 to 200,000 personnel and coalition casualties ultimately reaching between 1,000 and 3,000, the intervention drew in regional powers including states from the Gulf, North Africa, and the broader Arab world, transforming the conflict into one of the largest multilateral military engagements in the region in decades.
- September 2015 Marib Toshka missile attack
January 1, 2015
The September 2015 Tochka missile strike on the coalition base at Safer in Marib Governorate was among the deadliest single attacks on Saudi-led coalition forces in the Yemeni Civil War. The OTR-21 ballistic missile struck an ammunition dump, triggering a secondary explosion that killed 52 Emirati, ten Saudi, five Bahraini, and 36 pro-Hadi Yemeni soldiers. The scale of Emirati losses in particular marked the attack as a significant blow to coalition cohesion and demonstrated the Houthis' capacity to employ ballistic missiles with effect against fixed military installations. The strike underscored the vulnerability of coalition logistics and staging areas in Marib Governorate to precision or area-effect missile attack, complicating the coalition's operational posture in a governorate that held strategic value as both a front line and an energy-producing region.
- Battle of Al Mukalla (2016)
April 25, 2016
The Second Battle of Mukalla in April 2016 was a coalition offensive aimed at dismantling the al-Qaeda Emirate in Yemen by retaking Mukalla, which AQAP had established as its capital. The Saudi-led coalition, composed of Yemeni, UAE, and Saudi forces totaling around 2,000 personnel, defeated an AQAP force of approximately 1,000 fighters, inflicting over 1,100 casualties on the militant group. The coalition's capture of Mukalla and the surrounding coastal areas dealt a significant blow to AQAP's territorial ambitions in Yemen, effectively collapsing the administrative and logistical center the group had built into a functioning emirate. Within the broader Yemeni Civil War, the battle marked one of the most direct and consequential counterterrorism actions undertaken by coalition forces, demonstrating that the Saudi-led intervention extended beyond the Houthi conflict to address AQAP's parallel bid for territorial control in the south.
- Battle of Sana'a
November 29, 2017
- Battle of Aden (2018)
January 31, 2018
The Battle of Aden in January 2018 marked a significant fracture within the anti-Houthi coalition, pitting the Southern Transitional Council (STC) against the internationally recognized Yemeni government forces loyal to President Abdrabbuh Mansur Hadi. With both sides fielding forces of comparable size around the headquarters in Aden, the confrontation revealed that the coalition opposing the Houthi movement was not a unified front but a grouping of factions with competing political objectives. The STC sought greater autonomy or independence for southern Yemen, placing it at direct odds with the central government it nominally shared a coalition with. This intra-coalition conflict complicated the broader Yemeni Civil War by opening a second axis of armed contestation in the south, diverting resources and attention from the Houthi front and undermining the political coherence of the internationally backed government.
- Battle of Al Hudaydah
September 16, 2018
The siege of Al Hudaydah, conducted under the codename Operation Golden Victory, was the largest single battle of the Saudi Arabian-led intervention in Yemen since that intervention began in 2015. The operation was spearheaded by the United Arab Emirates and Saudi Arabia and directed against Houthi-held positions in the port city of Al Hudaydah. Control of the port carried strategic weight given its role as a primary entry point for goods into Yemen. Coalition forces under Tareq Saleh's command numbered approximately 25,000, substantially outnumbering estimated Houthi strength of between 1,000 and 10,000 fighters. Casualties were recorded on both sides, though the wide variance in reported figures reflects the contested nature of the battle's documentation.
- Battle of Al Masini valley
February 18, 2018
The Battle of Al Masini Valley, designated Operation Al Faisal by the Saudi-led coalition, represented a direct effort to dismantle an AQAP-controlled stronghold in central Hadhramaut governorate. The operation was carried out by the UAE-backed Hadhrami Elite Force under Faraj al-Bahsani, with support from the UAE Armed Forces, reflecting the coalition's broader counterterrorism campaign running parallel to its operations against Houthi forces in the Yemeni Civil War. Control of Al-Masini Valley held strategic relevance for AQAP's presence in Hadhramaut, a governorate the group had sought to exploit amid the wider conflict's instability.
- 2019 Southern Yemen clashes
August 7, 2019
The August 2019 clashes in Aden marked an open rupture within the Saudi-led coalition, pitting pro-Hadi government forces backed by Saudi Arabia against the Southern Transitional Council (STC), which had UAE backing. The STC's seizure of Aden and Zinjibar demonstrated that the anti-Houthi coalition was not a unified front but a coalition of actors with competing territorial and political objectives. Control of Aden, the internationally recognized government's seat of operations in the south, passing to the STC directly undermined the Hadi government's authority and complicated Saudi Arabia's broader war aims. The clashes exposed the divergence between Saudi and Emirati priorities in Yemen, with the UAE having built up the STC as a counterterrorism and southern secessionist partner distinct from the Hadi administration. This internal conflict opened a second front within the war, forcing coalition partners to contend with southern separatism alongside the ongoing Houthi insurgency in the north.
- Battle of the Jabara Valley
August 26, 2019
The Battle of the Jabara Valley was a component of Operation Victory from God, a major Houthi-led offensive conducted along the Saudi Arabian-Yemeni border. The engagement saw a Houthi force of approximately 4,000 fighters contest Saudi and allied units numbering between 1,100 and 2,000. Reported Saudi casualties in the range of 1,000 to 1,900 — potentially exceeding the entire force committed — indicate a severe military reversal. As part of a broader cross-border offensive, the battle demonstrated the Houthi movement's capacity to press operations into Saudi territory and sustain large-scale conventional engagements, placing pressure on Saudi border defenses and undercutting the coalition's strategic posture in the wider civil war.
- al-Jawf Offensive
February 29, 2020
The al-Jawf Offensive marked a significant Houthi territorial advance during the Second Yemeni Civil War, resulting in the capture of Al Hazm from the Hadi government on 1 March 2020 and the seizure of approximately 3,500 square kilometers of Al Jawf Governorate by 27 April. The offensive unfolded in two phases: the first consolidating Houthi control over the governorate, and the second, launched on 27 May, pushing toward the strategically important city of Marib. The capture of the Maas military base on 20 November 2020 extended Houthi reach and set conditions for a subsequent offensive against Marib city launched in February 2021. The Houthis' deliberate pauses to reinforce and adapt to shifting coalition dynamics — including changes in the Saudi-led coalition and the Southern Transitional Council — demonstrated an ability to calibrate operational tempo to the broader political and military environment. The offensive represented one of the more consequential Houthi territorial gains of the war, bringing pressure on Marib, the Hadi government's last major northern stronghold.
- 2022 Abu Dhabi attack
January 17, 2022
The January 2022 Houthi strike on Abu Dhabi marked a significant escalation in the Yemeni Civil War, extending the conflict's reach directly into the territory of a leading member of the Saudi-led coalition. By targeting oil tanker trucks and airport construction infrastructure in Abu Dhabi, the Houthi movement demonstrated a capacity and willingness to strike civilian and economic targets deep inside the UAE. The attack killed 3 civilians and wounded 6, underscoring that coalition member states were no longer insulated from the consequences of their military involvement in Yemen. The strike placed pressure on the UAE domestically and signaled that Houthi drone and ballistic missile capabilities had matured to the point where interception systems alone could not guarantee protection of the coalition's home territory.
- Red Sea crisis
October 19, 2023
The Red Sea crisis represents a significant expansion of the Yemeni Civil War's regional footprint, with Houthi forces extending their military operations beyond Yemeni territory to target maritime traffic in the Red Sea and launch missiles and drones toward Israel. By attacking dozens of merchant and naval vessels they claimed were linked to Israel, the Houthis disrupted one of the world's major commercial shipping corridors, drawing military responses from Israel, the United States, and the United Kingdom. The crisis is embedded within overlapping regional conflicts, including the Iran–Israel proxy conflict and the broader Middle Eastern crisis triggered by the Gaza war, demonstrating how the Yemeni conflict had become a node in a wider network of hostilities rather than a self-contained civil war.

An Islamist insurgency is taking place in the Maghreb region of North Africa, followed on from the end of the Algerian Civil War in 2002. The Algerian militant group Salafist Group for Preaching and Combat (GSPC) allied itself with al-Qaeda to eventually become al-Qaeda in the Islamic Maghreb (AQIM). The Algerian and other Maghreb governments fighting the militants have worked with the United States and the United Kingdom since 2007, when Operation Enduring Freedom – Trans Sahara began.
WAR· 2003
conflict in the Niger Delta
The current conflict in the Niger Delta first arose in the early 1990s over tensions between foreign oil corporations and a number of the Niger Delta's minority ethnic groups who feel they are being exploited, particularly the Ogoni and the Ijaw. Ethnic and political unrest continued throughout the 1990s despite the return to democracy and the election of the Obasanjo government in 1999. Struggle for oil wealth and environmental harm over its impacts has fueled violence between ethnic groups, causing the militarization of nearly the entire region by ethnic militia groups, Nigerian military and police forces, notably the Nigerian Mobile Police. The violence has contributed to Nigeria's ongoing energy supply crisis by discouraging foreign investment in new power generation plants in the region.
