The World Health Organization reported today that it has successfully delivered basic medical assistance to besieged areas in the Yemeni city of Taiz. A statement released here by WHO said that it had delivered 20 tons of assistance and materials to hospitals in the besieged area as hospitals accommodate a big number of those suffering from war erupting around the area. The report added that the Houthi militia has managed to prevent the access of medical assistance and basic food materials over the last three months, threatening the lives of thousands of civilians in Taiz.
