(Reuters) – Eight-year-old Abdullah Ali lay screaming in pain in a Sanaa hospital on Wednesday as a doctor cleaned his torn face, the victim of a worsening war that threatens millions of Yemenis with starvation and homelessness. “We were at home when air strikes hit the missile base on the mountain near our house,” Abdullah’s father Musleh said by his bedside, describing an air raid on an arms depot a month ago that sent missiles raining across part of Yemen’s capital.
