Yemen has been engulfed in a complex civil war since 2014, pitting the Iran-aligned Houthi movement against a Saudi-backed government that was forced to flee the capital, Sanaa. In 2015, a Saudi-led coalition including the United Arab Emirates intervened militarily to restore the government. Over time, however, deep fractures emerged within the coalition itself.
One of the most significant rifts has involved the Southern Transitional Council (STC), a UAE-backed separatist group seeking autonomy or independence for southern Yemen. Although the STC was initially aligned with Saudi Arabia, it later clashed with Saudi-supported government forces. Since 2022, the STC has been part of a fragile power-sharing arrangement, but tensions have remained high, particularly in the strategically vital eastern province of Hadramout.
What Happened
The Saudi-led coalition carried out a limited air strike on Yemen’s Mukalla port after alleging that two ships arriving from the UAE port of Fujairah unloaded large quantities of weapons and combat vehicles to support the STC. According to the coalition, the ships entered the port without authorisation and disabled their tracking systems.
The air strike, conducted early Tuesday, targeted the dock where the weapons were reportedly unloaded. Saudi state media said the operation was carried out at the request of Yemen’s Presidential Leadership Council chief, Rashad al-Alimi, and resulted in no casualties or collateral damage. The UAE has not publicly commented on the allegations.
Why It Matters
The strike underscores growing tensions between Saudi Arabia and the UAE, once close allies in the Yemen war, and highlights the fragility of the current power-sharing arrangements. Mukalla lies in Hadramout, a province bordering Saudi Arabia that is of high strategic importance due to its location, resources, and historical ties to the kingdom.
By targeting alleged arms support for the STC, Riyadh is signaling that it will not tolerate unilateral military moves by its partner-turned-rival, nor external backing of Yemeni factions without Saudi-backed government approval. The incident raises the risk of a broader confrontation between Saudi-supported and UAE-backed forces, potentially destabilising eastern Yemen.
Saudi Arabia: Leads the coalition and seeks to maintain influence in eastern Yemen while preventing separatist expansion that could threaten its border security.
United Arab Emirates: Backs the STC and has significant influence in southern Yemen, though it officially denies destabilising actions.
Southern Transitional Council (STC): A powerful southern separatist group seeking autonomy or independence, with strong military control on the ground.
Yemeni Government / Presidential Leadership Council: Internationally recognised authority reliant on Saudi support, aiming to preserve territorial unity.
Houthis: Control northern Yemen and remain the main adversary of the Saudi-backed government, benefiting indirectly from divisions among their rivals.
What’s Next
The immediate risk is further escalation between Saudi-aligned and UAE-backed forces in Hadramout and neighbouring al-Mahra. Riyadh may increase military or diplomatic pressure to curb STC expansion, while the UAE could push back quietly through its local allies.
In the longer term, the incident exposes the limits of Yemen’s power-sharing framework and complicates efforts to end the war. Continued infighting among anti-Houthi factions could weaken negotiations with the Houthis and prolong instability, even as Saudi Arabia seeks an exit from the conflict and a broader regional de-escalation.
