Yemen’s STC Seizes Oil Provinces, Heightening Civil War Tensions

In a significant escalation of the Yemeni civil war, the Southern Transitional Council (STC) has seized control of the oil-rich provinces of Hadramout and Mahra, undermining the fragile ceasefire that had prevailed in recent years. Backed by the United Arab Emirates, the STC’s unopposed military advances not only consolidate its power but also threaten the legitimacy of the internationally recognized Yemeni government. This development raises urgent concerns over the future political landscape in Yemen and the potential for renewed civil strife among factions in the ongoing conflict.

Background & Context

The Southern Transitional Council (STC) was established in 2017 with the objective of restoring South Yemen as an independent state, a status that existed prior to Yemen’s unification in 1990. Since its formation, the STC has gained substantial influence, notably supported by the United Arab Emirates. The ongoing civil war in Yemen, which began in 2014, has complicated the geopolitical landscape, drawing in various regional powers. As the Houthis maintain control over the north, the STC competes with the internationally recognized Yemeni government for dominance in the south, especially in economically vital areas like Hadramout.

Efforts to secure a peaceful resolution in Yemen have often faltered due to conflicts over governance and territorial integrity. The current dynamics suggest a significant departure from earlier agreements aimed at unifying the anti-Houthi forces, raising concerns about the sustainability of any proposed peace process in a region burdened by humanitarian crises and shifting alliances.

Key Developments & Timeline

In recent months, significant political and military changes have occurred in southern Yemen, particularly concerning the Saudi leadership and the effectiveness of the Southern Transitional Council (STC). Below is a timeline of the key developments that have shaped the situation in the region.

Early December 2025: Saudi Arabia reallocates military resources away from southern Yemen, indicating a significant strategy shift.
December 9, 2025: STC forces seize control of Hadramout and Mahra provinces, leading to a disruption of the fragile ceasefire that had been established in recent years.

The STC’s military actions were largely unopposed, leveraging superior equipment and receiving substantial support from the United Arab Emirates (UAE). Control over Hadramout is especially crucial as the province is vital for Yemen’s economy due to its rich oil reserves, essential for the southern regions of the country.

However, the political maneuvers by the STC have complicated the cooperation dynamics within the anti-Houthi coalition, thereby increasing the risk of civil strife among factions. Meanwhile, Saudi Arabia attempts to maintain a delicate balance by mediating tensions while also withdrawing some military units from Aden.

The situation remains tense, with the threat level classified as high in the affected regions of southern Yemen, particularly in Hadramout and Mahra, as the complexities of military control and political alliances unfold. The outcomes of these developments may have lasting impacts on the stability and security of the region.

Official Statements & Analysis

In a recent escalation in Yemen, Yemen analyst Ahmed Nagi noted, “The group has gone beyond the Saudi-led arrangements,” highlighting the shifting dynamics in the ongoing civil war. Maj. Gen. Mohammed al-Qahtani, chairman of the Saudi delegation, firmly stated, “We reject any attempts to impose a fait accompli,” emphasizing the challenge posed by the Southern Transitional Council (STC) to the internationally recognized Yemeni government.

The current landscape indicates a potential for increased military conflict as the STC’s seizure of the oil-rich provinces of Hadramout and Mahra threatens to destabilize an already fragile ceasefire. This escalation reflects not just a territorial grab, but a fight for control over crucial resources, which could lead to heightened violence and economic instability across Yemen. As regions fall under the influence of different factions—backed by international entities like the UAE—the implications for nuclear threat preparedness and broader regional stability become increasingly pertinent. Monitoring these shifts is essential for mitigating risks of civil unrest and future humanitarian crises within Yemen and beyond.

Conclusion

In summary, the recent territorial expansion of the Southern Transitional Council (STC) in Yemen has significant implications for the country’s ongoing civil conflict. As the STC consolidates its control over oil-rich provinces like Hadramout and Mahra, tensions mount between anti-Houthi factions, which threatens the fragile balance of power and the legitimacy of the internationally recognized Yemeni government. This development not only highlights the complexities of local alliances but also reflects the competition for resources that may lead to renewed conflict and humanitarian crises, complicating future operations and peace efforts. Moving forward, it will be crucial for regional stakeholders to monitor these changes closely, as the potential for increased violence and instability looms large over Yemen’s political landscape.
