Yemen, on brink of collapse, may suffer further.

A 4 months old, all Hussain Al-Kholani has ever known is war and want — he weighs just 4 1/2 pounds, less than a third of the average American baby at that age.

“Hussain’s suffered from malnutrition since he was born,” Ali Hussein Al-Kholani, the boy’s father, told ABC News. “They tell me to take him to the malnutrition clinic in [Yemen’s capital of] Sanaa, but I don’t have any way to get him there.”

Ali Hussein can’t work and is forced to feed his family — his son, daughter, wife, and four brothers — by relying on food handouts from aid agencies.
