Yemeni children collect clean water in Sanaa

A Yemeni child holds a water bottle to be filled with clean water, in Sanaa, Yemen, on Oct. 22, 2018. Millions of desperate children and families across Yemen could soon be without food, clean water or sanitation because of the deepening economic crisis and unrelenting violence in the port city of Hodeidah, warned the UN Children's Fund (UNICEF) last Thursday.
