By Reuters Staff 2 Min Read DUBAI (Reuters) - Aid agencies have so far received only $374 million of the $3.85 billion the United Nations says is needed this year for Yemen to avert what threatens to become the world’s worst famine in decades, the United Nations humanitarian office said on Tuesday. Locked in war for more than six years, the country is already suffering from the world’s worst humanitarian crisis and the situation is at risk of deteriorating further, the U.N. Office for the Coordination of Humanitarian Affairs (UNOCHA) said. “Yemen is approaching the point of no return. If we make the wrong choice now, Yemen will experience the worst famine the world has seen in decades,” UNOCHA Yemen coordinator David Gressley said.
