By Syndicated Content Mar 1, 2021 5:36 AM SANAA (Reuters) - Unable to find work, Ahmed Farea has sold everything including his wife's gold to feed and house two young daughters in one small room. Elsewhere in Yemen's capital Sanaa, widow Mona Muhammad has work but struggles to buy anything more nutritious than rice for her four children amid high prices. And in a nearby hospital, severely malnourished children receive lifesaving nutritional drinks. Across the country Yemenis are exhausting their coping mechanisms, and children are starving, amid the world's largest humanitarian crisis. On Monday the United Nations hopes to raise $3.85 billion at a virtual pledging event to avert what the U.N. aid chief has said would be a large-scale "man-made" famine, the worst the world will have seen for decades.
