“Signing the agreement, which is the fruit of long and relentless efforts exerted by our brothers in Saudi Arabia and the UAE, will be a turning point in the battle against the Houthi militia and a new stage towards strengthening relations between the Arab Coalition and STC,” said Nizar Haitham, spokesman for the STC. CAIRO (Reuters) – Separatists in southern Yemen have suspended their participation in consultations on a power-sharing agreement in the south known as the Riyadh Agreement, according to a statement from the Southern Transitional Council (STC) on Tuesday. Observers believe that the main obstacle to the Riyadh agreement is not to withdraw from the Abyan confrontation zones or form a government, but to push both sides to the agreement to make painful concessions, provided for by the agreement, with regard to the later stages of military and security measures, which include the transfer of heavy weapons and the withdrawal of armed forces from the provinces. each party for its own area of influence, as is the case for Shabwa governorate, which the Muslim Brotherhood considers one of their main strongholds after losing Al-Jawf and Nehm, while the STC does not seem to accept the idea of abandoning its security influence in Aden in the face of the growing lack of trust between the two sides. “All necessary steps have been taken to speed up the implementation of the Riyadh agreement from today,” quoted the official SPA news agency, an unse named coalition official. “All the parties are winners with the agreement, and the only loser is the Houthis,” Mr. Al Homaidi said. In a statement to The Arab Weekly, the deputy head of the STC`s media department, Mansour Saleh, said, “The council considers the serious direct implementation of the agreement a great achievement that enhances the security situation and completes the implementation of what was agreed as agreed in Riyadh under Saudi apices.” Al Jazeera looks below at some of the key features of the agreement. “We highly appreciate the relentless efforts of our brothers in KSA to accomplish the agreement and work to unite the Yemenis against challenges, especially the Iranian threat and its proxy Houthis,” Mr Al Eryani wrote on Twitter.
