The head of the United Nations World Food Program has described Yemen as "the worst place on earth," after visiting the war-stricken nation, which is on the brink of famine.
David Beasley says the UN food agency is underfunded and will need billions of dollars in private donations in order to meet its targets.
"In a children's wing or ward of a hospital, you know you normally hear crying and laughter. There's no crying, there's no laughter, there's dead silence," says Mr Beasly.
"This is hell," he said. "It's the worst place on earth. And it's entirely man-made."
The UN has warned that half of Yemen’s population could face serious food insecurity and tens of thousands already live-in famine-like conditions.
