On Friday the UN's humanitarian coordinator, Stephen O'Brien, called for an urgent mobilisation of funds to "avert a catastrophe" in Nigeria, Somalia, South Sudan and Yemen.
"Otherwise, many people will predictably die from hunger, livelihoods will be lost and political gains that have been hardwon over the last few years will be reversed," O'Brien said in his warning to the UN Security Council.
"Without collective and coordinated global efforts, people will simply starve to death. Many more will suffer and die from disease. Children stunted and out of school. Livelihoods, futures and hope will be lost."
"We stand at a critical point in our history," he said. "Without collective and coordinated global efforts, people will simply starve to death."
"All four countries have one thing in common. Conflict," he said. "This means that we, you, have the possibility to prevent and end further misery and suffering... It is all preventable. It is possible to avert this crisis, to avert these famines — to avert these looming human catastrophes."
He called war-wracked Yemen "the largest humanitarian crisis in the world," with two-thirds of the population, or 18.8 million people in need of assistance and more than seven million with no regular access to food.
With a situation as horrific as this it is hard to know how to respond - which makes this a great time for prayer! We encourage you to learn more about the crisis in these four nations in order to make your prayers informed.
