Yemeni children collect clean water in Sanaa

A Yemeni child sits among water bottles while he waits to collect 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.
