RIYADH — There has been a big response from tribes in Yemen to the Operation Decisive Storm, Brig. Gen. Ahmad Al-Asiri, spokesperson of the coalition forces and adviser at the office of the minister of defense said, valuing the efforts of the tribes of Shabwa, Abyan, Lahj, and Yafea who announced their loyalty to the legitimacy and their full support to Yemeni President Abdrabbu Mansour Hadi. “Communications are going on with these tribes to coordinate work and provide them necessary support,” he told a regular news briefing here on Sunday. Asiri said humanitarian work has become more organized. The Red Cross sent three relief planes, and coordination is going on with it to facilitate relief operations in the region. Airstrikes are continuing to target rebel brigades and their assembly points in army camps. Brigade 310 in Sanaa, brigade 22 in Taiz and camps in Matarah in the Razeh region were targeted. Many caves in which a big number of the Houthi militias were holed up were also targeted, said Asiri. The coalition forces also targeted the Saada airport which the Houthis were trying to use. The coalition forces are supporting the people's committees in Aden and the northern regions, specially Saada and the surrounding areas to prevent the Houthis from getting logistics and military support. The spokesperson said the Houthis are preventing citizens from getting fuel, and diverting it for their military operations. That's why the coalition forces targeted many locations used for storing fuel. Asiri said the Houthis were trying to shift the battle toward the Saudi borders by involving the Saudi ground forces in wider ground operations. They targeted the Najran border sector on Saturday, but the attack was repulsed with the use of Apache helicopters and artillery. This resulted in the martyrdom of three Saudi soldiers, he added.
