The former capital Sanaa in the north of Yemen is in territory controlled by the Iranian-supported Houthi rebels. A recent Reuters article reported on the issue: “Saudi Arabian forces have taken over control of Yemen’s southern port of Aden as part of efforts to end a power struggle between the Saudi-backed Yemeni government and southern separatists, four sources familiar with the matter said.”
The Saudi control is temporary
The Saudi control will last while a neutral force with militias from the various parties is set up to police and defend the port. When this happens the Saudis ad well as the UAE forces plan to withdraw.
Southern Transitional Council to have representation in the Saudi-backed government
Under the deal the separatist Southern Transitional Council (STC) are to get some additional representation in the Saudi-backed government of Mansur Hadi. Because of the security situation Hadi remains in exile in Saudi Arabia. The exact terms of the agreement have yet to be announced.
Earlier STC with UAE backing had seized Aden
While both the Saudis with the UAE and the STC are in a coalition fighting with the Houthi rebels in control of much of the north, the Saudis ultimate aim is to form a unified government under the control president Hadi. However the STC wants ultimately to create a separate independent South Yemen as existed some time ago. The STC was unable to move beyond control of Aden a few adjoining areas and both sides have tried to resolve their conflict. It seems they now have an agreement at least for now.
A recent article reports: “Saudi Arabia has been hosting indirect talks for a month between Hadi’s government and separatist leaders. Sources had said the two sides were close to agreeing a Saudi proposal to give the STC seats in the cabinet and place separatist forces under government command.”
Saudis may be settling their dispute with the STC prior to talks with the Houthis
A recent article suggests: “Saudi Arabia may have decided to unify the forces behind Hadi before responding to an offer by the Houthis to stop aiming missiles and drones at Saudi Arabia if the coalition halts air strikes on Yemen.”
