Yemen's foreign minister called on Tuesday for Arab ground intervention against the Houthis "as soon as possible." Asked in interview by Al Arabiya News Channel's sister channel Al Hadath whether he sought Arab ground intervention, Riad Yassin said: "Yes, we are asking for that, and soon as possible, in order to save our infrastructure and save Yemenis under siege in many cities." Yassin also revealed that Yemeni President Abdrabbu Mansour Hadi will be officially asking to join the Gulf Cooperation Council within the coming days. Yassin added that the war that has plagued Yemen is the doing of the Houthi rebels. For six days, a Saudi-led coalition of ten regional countries has bombed Iran-allied Houthi fighters and army units linked to former president Ali Abdullah Saleh. Saudi Arabia has vowed to keep up the raids until the rebels abandons their insurrection against Hadi, who has fled to Riyadh and whose last bastion in the southern city of Aden was heavily shelled overnight. Saudi Arabia's Foreign Minister Prince Saud al-Faisal also reiterated on Tuesday that the air campaign, dubbed "Operation Decisive Storm," will continue until Yemen is "stable and unified." "Operation Decisive Storm will continue to defend legitimacy in Yemen," al-Faisal said during his speech at the weekly meeting of the Shura Council in the capital Riyadh. "We are not advocating war, but we are ready for it," he said. Yassin also revealed that his ministry is resuming its work in the Saudi capital Riyadh for the time being, and that it is working tirelessly to find solutions for some Yemeni citizens who are stranded in some countries.
