The death toll continues to climb in Yemen, as scores of children are lost to starvation or disease with each passing day.
And now a recent decision by the Saudi-led military coalition to close all borders in response to a rebel missile strike threatens to stall critical relief operations.
UNICEF Executive Director Anthony Lake, World Health Organization Director General Dr. Tedros Adhanom and World Food Program Executive Director David Beasley issued a joint statement on Nov. 16 calling for the immediate reopening of all air, land and sea ports to allow medicine, food, fuel and other supplies to get through.
Without food or safe water, the threat of famine grows by the day.
"Without fuel, the vaccine cold chain, water supply systems and wastewater treatment plants will stop functioning," the UN officials warn. "Without food or safe water, the threat of famine grows by the day."
UNICEF and partners have been on the ground in Yemen since civil war broke out in March 2015. The ongoing conflict has affected more than 80 percent of the country's population, leaving nearly 21 million people in need of some form of assistance.
Response efforts include providing clean water, stopping the spread of waterborne illness and bringing therapeutic food to starving children. Some 17 million people do not know where their next meal is coming from, and 7 million are completely dependent on food assistance. An estimated 400,000 children are suffering from severe acute malnutrition, or SAM, which is life-threatening.
Yemen is also battling the largest and fastest-spreading cholera outbreak in modern history. Since April, there have been 900,000 suspected cases and close to 2,200 deaths.
Cholera is preventable and treatable but particularly dangerous and difficult to stop in humanitarian crises. A highly contagious bacterial infection of the intestines, it causes severe vomiting, diarrhea and dehydration, and if left untreated, can be fatal in young children, especially those who are malnourished.
