The world is facing its largest humanitarian crisis since 1945, the United Nations says, issuing a plea for help to avoid "a catastrophe".
UN humanitarian chief Stephen O'Brien said that more than 20 million people faced the threat of starvation and famine in Yemen, Somalia, South Sudan and Nigeria.
Unicef has already warned 1.4m children could starve to death this year.
You can't have it both ways. Either we stay out of other people's affairs, or, as I said in the Syria thread, for serious matters we get involved.
Do we let let all starve?
