Saudi‑aligned forces pull back toward Aden as Ansarallah advance threatens last Yemeni coastal highway

Saudi‑aligned Southern Armed Forces are withdrawing from Yemen’s southwestern coast toward Aden because Ansarallah’s advance from the north threatens to cut the last remaining highway, raising the risk of new territorial gains for the Houthi‑aligned movement and fresh pressure on the government’s interim capital.

Ansarallah’s rapid advance along Yemen’s southwestern coast is forcing Saudi‑aligned forces to pull back and could soon reshape control of key Red Sea approaches.

The Southern Armed Forces, aligned with Yemen’s Presidential Leadership Council (PLC) and backed by Saudi Arabia, announced that they are withdrawing from the southwestern coastline toward the city of Aden. They linked the move directly to Ansarallah’s advance from the north and the risk that the last remaining highway in the area could be physically cut.

This suggests that pro‑government units fear being trapped along exposed stretches of coast. By moving before road links are severed, they aim to avoid encirclement and regroup in positions they view as more defensible around Aden. It isn’t yet clear whether all PLC‑aligned forces will leave the area or whether some will try to hold ground along the coast.

For communities on Yemen’s southwestern seaboard, a rapid change in control could mean new displacement and uncertainty about access to aid and basic services. Areas that have been run by the PLC or Southern Armed Forces may shift to Ansarallah’s rules and administrative style, forcing humanitarian organizations that rely on road access to rethink how and where they deliver assistance.

Aden, the interim seat of Yemen’s internationally recognized government, faces growing strain if the last highway from the southwest is cut while Ansarallah expands its grip on coastal territory to the north. That would complicate the movement of supplies and personnel by land and increase dependence on sea and air routes.

Strategically, the reported advance strengthens Ansarallah’s hand along the Red Sea at a moment when it is already involved in attacks on commercial shipping in the wider region. Observers warn that if Ansarallah secures the Red Sea coast and the Bab el‑Mandeb area, it would gain greater leverage over vital trade lanes between Europe and Asia.

For Saudi Arabia and its allies, the Southern Armed Forces’ withdrawal is a setback to maintaining a buffer on the coast. It improves Ansarallah’s position in any future negotiations and reduces coalition options for applying military pressure without accepting higher risk to their own forces and infrastructure.

Shipping companies and insurers are already dealing with intermittent missile and drone threats linked to Ansarallah. A more consolidated stretch of coastline under its control near Bab el‑Mandeb could expand the set of vessels at risk and complicate route planning, even if foreign navies increase patrols.

Control of a single highway is becoming a key factor in the balance between the PLC and Ansarallah in this part of Yemen, because both depend on narrow coastal corridors for resupply and political presence.

The signals to watch now are whether Ansarallah claims full control over specific coastal districts, whether it moves to secure the threatened highway, and whether PLC‑aligned forces attempt any counter‑moves or focus instead on shoring up defenses in and around Aden. Changes in foreign naval deployments in the Red Sea will show how regional powers weigh the coastal shift.
