Socotra

Overview

Socotra is the largest island in a Yemeni archipelago at the eastern approach to the Gulf of Aden. The island and its smaller neighbors lie along maritime routes connecting the Arabian Sea with the Bab-el-Mandeb Strait, the Red Sea and the Suez Canal. This position gives Socotra strategic importance beyond its size: activity around the archipelago can affect access to a route used by commercial vessels traveling between Asia, the Middle East and Europe. Socotra is part of Yemen, although control of the island became a point of contention during the Yemeni civil war.

The island’s modern history is closely tied to the struggle between Yemen’s government and the Southern Transitional Council (STC), a southern political and military movement. STC forces seized Socotra in June 2020, removing it from Yemeni government control. Saudi Arabia mediated a proposed reversal under a mechanism for implementing the Riyadh Agreement, but the deadline for restoring the earlier conditions on Socotra passed without progress. The island also became part of the United Arab Emirates’ network of maritime facilities near Bab-el-Mandeb. Its documented Emirati presence must be distinguished from reports and rumors about a possible Israeli facility elsewhere in the archipelago.

Geography

Socotra occupies a position between the Arabian Sea and the Gulf of Aden, southeast of Yemen’s mainland and east of the Horn of Africa. Its location connects two geographic settings: the open waters of the northwestern Indian Ocean and the approaches to the narrow Bab-el-Mandeb Strait. Ships proceeding toward the Red Sea pass through this wider maritime area before reaching the strait. For a state or armed force concerned with shipping, an island in this position can support observation, air access and maritime logistics even though it does not itself sit inside Bab-el-Mandeb.

The name Socotra also refers to an archipelago rather than the main island alone. Abd al-Kuri is one of its outlying islands. This distinction matters in accounts of proposed military facilities: reports concerning an Israeli base identify Abd al-Kuri, while accounts of Emirati activity describe a broader presence across the Socotra archipelago. The UAE controls landing strips and small port terminals there and has established a base on Socotra. Those facilities form part of a wider Emirati network associated with the approaches to Bab-el-Mandeb, including facilities on the Yemeni island of Perim and positions elsewhere around the Red Sea and the Horn of Africa.

Socotra’s value is therefore geographic as well as political. A landing strip allows access to a remote island without reliance on a mainland road network; a small port terminal permits vessels to use the archipelago as a maritime point of support. Facilities spread among islands can serve different functions from a single installation on the main island. They also make changes in control consequential for Yemen’s government, for regional states seeking reliable access to the sea, and for vessels navigating waters exposed to threats from Yemen’s conflict.

Modern history

Socotra’s strategic position attracted interest before the current Yemeni war. Earlier discussion of security arrangements in Yemen included speculation about foreign installations on the island. Such interest reflected the same enduring geographic fact that shapes present policy: Yemen’s islands and ports offer access to sea lanes linking the Arabian Sea, Gulf of Aden and Red Sea. The question of who controls a facility on Socotra is consequently separate from, but connected to, the question of who governs Yemen’s mainland.

During the Yemeni civil war, divisions emerged among forces opposing the Houthis, a terrorist organization backed by the Iranian regime. The STC developed armed formations and sought a greater role in governing southern Yemen. Its contest with Yemen’s government was especially consequential in Aden, the southern port city, and in Abyan Governorate. These conflicts were not confined to the mainland. Socotra became another place where a dispute over southern political authority translated into a change in territorial control.

The Riyadh Agreement, signed in 2019, was intended to bring Yemen’s government and the STC into a power-sharing arrangement and resolve military and security disputes between them. Implementation stalled. The STC withdrew from the agreement’s military component, and the sides entered a renewed armed confrontation. Battles in Abyan Governorate did not produce a decisive outcome. Against that background, events escalated on Socotra, where STC forces took control of the island. The seizure placed Socotra outside the Yemeni government’s control and made its restoration a specific issue in Saudi mediation.

The sequence of the 2020 confrontation helps explain why an island far from Aden became central to negotiations. STC-linked forces declared self-administration in April. Yemen’s government launched an unsuccessful offensive in Abyan in May, after which neither side made substantial gains during weeks of fighting. On June 20, STC forces seized political control of Socotra. The takeover gave the council a position beyond its mainland strongholds while adding a new obstacle to any agreement intended to restore a single chain of government authority.

Saudi Arabia then promoted a mechanism to accelerate implementation of the Riyadh Agreement. Yemen’s government accepted the proposed mechanism. It called for STC candidates to be appointed governor and security director of Aden Governorate. In exchange, Saudi guarantees were to support implementation of the military component, STC forces were to withdraw from Aden, and conditions on Socotra were to return to those that had existed about a month before the takeover. A new Yemeni government including the STC would follow. The arrangement linked appointments, military withdrawals and control of Socotra rather than treating the island as an isolated dispute.

The proposed sequence also showed why restoring government control over Socotra proved difficult. Political appointments in Aden offered the STC a share of authority, while withdrawal and restoration of earlier conditions required changes by armed forces on the ground. Saudi guarantees were meant to connect those steps. The implementation deadline nevertheless passed without progress on restoring the earlier conditions on Socotra. Both the island’s situation and the Riyadh Agreement’s military and security provisions remained unresolved at that deadline.

Regional competition added another layer to the island’s politics. The UAE supported southern forces during the Yemeni war and maintained a presence around maritime routes near Yemen. Its base on Socotra belongs to a network extending toward Bab-el-Mandeb. Emirati facilities in the archipelago are also part of an effort to counter threats from the Iranian regime and the Houthis to freedom of navigation and to prevent weapons smuggling to Yemen. Socotra has been described as a UAE regional stronghold alongside positions in Puntland and Darfur. That wider setting explains why a change in control on the island has implications for states operating well beyond Yemen.

Security

The UAE’s documented position on Socotra consists of its base and its control of landing strips and small port terminals in the archipelago. Those facilities support a regional approach to maritime security at a time when Houthi attacks have threatened vessels in and beyond the Red Sea. The UAE links its island presence to the danger posed by the Houthis and the Iranian regime to shipping, as well as to the movement of weapons into Yemen. Control of a landing strip or terminal is significant because it can support access, supplies and observation over a dispersed maritime area.

Separate reports have described prospective military cooperation among Israel, the UAE, Saudi Arabia and other states in the Socotra archipelago. Reports have also described construction of an Israeli military base on Abd al-Kuri. In that account, the facility could serve as a launch site for Israeli interceptor aircraft if early intelligence warnings identified a missile launch. This is a reported proposal and reported construction, not an established description of an operating Israeli base. The suggested interceptor role depends on warning time as well as aircraft access: proximity to a launch area alone would not establish that an interception mission could be carried out.

Rumors of a UAE–Israel spy base entered the rhetoric of Al-Qaeda in the Arabian Peninsula (AQAP), an Al-Qaeda branch based in Yemen. AQAP issued a statement concerning media reports of an Israeli military base on Socotra. It focused on the rumored joint spy base and criticized the UAE. Its statement did not address the Abraham Accords. The statement illustrates how claims about facilities on the archipelago circulated among armed groups, while the established Emirati infrastructure and the reported Israeli plans remain distinct matters.

Socotra also lies near waters in which the Houthis have extended their attacks and threats against shipping. Their capacity to threaten maritime traffic does not depend on controlling every island or stretch of coast beside a route. Missiles and drones can endanger vessels at considerable distance from a launch point. In April 2024, a drone targeted the MSC Orion about 200 nautical miles southeast of Socotra in the Indian Ocean; no injuries or significant damage were reported. That incident showed why security discussions about the island cannot be limited to the waters immediately off its shore.

On December 27, 2024, Houthi military spokesman Yahya Saria claimed responsibility for a drone attack on the Santa Ursula in the Arabian Sea east of Socotra. He linked the claimed attack to the Houthi ban on ships entering Israeli ports. The Santa Ursula attack claim was unverified. Its location and stated rationale nevertheless placed Socotra within the geography of the Houthi campaign against commercial shipping, in which vessels far from the Bab-el-Mandeb Strait could be named as targets.

The distinction between a claimed attack and a verified one is important in assessing maritime events near Socotra. Armed groups can announce operations without independent confirmation that a vessel was struck. The December 2024 Santa Ursula statement records what the Houthis claimed and why they said they acted; it does not establish that the claimed drone attack occurred. By contrast, the known UAE facilities describe an existing regional presence, while accounts of an Israeli installation on Abd al-Kuri remain reports. Treating these different forms of information separately gives a clearer account of the archipelago’s security role.

Present day

Control of Socotra remains part of the broader question of how Yemen’s competing authorities exercise power. The STC takeover removed the island from Yemeni government control, while the Saudi-mediated mechanism for reversing that change did not meet its restoration deadline. The unresolved military and security provisions of the Riyadh Agreement show how agreements reached between political leaders can fail to change conditions at a strategically valuable location. Socotra’s distance from Yemen’s mainland does not separate it from the country’s central political dispute.

Events on the island have also raised questions about the treatment of journalists. On May 28, 2023, officials affiliated with the STC arrested two French journalists on Socotra, Quentin Mueller and Sylvain Mercadier. The officials demanded the names of their sources and the places where they had met them. They confiscated the journalists’ passports, laptops, cameras and books. Mueller was questioned about his earlier reporting on UAE interference in Yemen in a 2021 Al Jazeera documentary. The arrests showed how control over access and information could be exercised by officials affiliated with the force holding the island.

Socotra thus occupies several roles at once. It is a Yemeni island and the center of an archipelago near a major maritime route. It is a site where STC forces displaced Yemen’s government and where a Saudi-mediated settlement failed to restore earlier conditions by its deadline. It hosts documented Emirati infrastructure intended to support regional maritime security. It is also the subject of reported, unconfirmed plans involving Israel and of rhetoric from AQAP, while Houthi claims and attacks have brought the surrounding sea lanes into the conflict. Keeping these developments in their proper sequence and evidentiary categories is essential to understanding the island’s place in Yemen and the wider region.
