Sanaa, August 28 (RHC)-- At least five Yemenis were killed and nearly 10 others were reported injured in Saudi air raids on Razeh district in the northern province of Sa'ada on Thursday. Three others had been killed in earlier attacks on Barazah district, along Saudi border in the same province. Sources close to the Ansarullah movement said the morning attack on Sa'ada targeted residential buildings as well as farmlands and livestock farming facilities in rural areas, while heavy damage was inflicted on a number of roads and vehicles. Elsewhere, Saudi fighter jets carried out over a dozen strikes on the central province of Ma'rib. Sources on the ground counted at least 15 air attacks in the provincial capital which is called by the same name, with the most notable of them targeting the al-Mennah neighborhood south of the city. In retaliation, Ansarullah fighters and allied army units fired rockets at a Saudi military base in southern Jizan province. Earlier, Yemeni forces launched a Scud missile into the same region. Health sources in Yemen say more than 5,000 people, most of them civilians, have lost their lives since Riyadh unleashed its war on Yemen over five months ago. The air campaign, which lacks any mandate from UN, is meant to stop the advance of Ansarullah across Yemen and restore power to the fugitive president Abd Rabbuh Mansour Hadi.
