Aid agencies are appealing for US$1.6 billion in the face of what the UN humanitarian chief  has described as a “looming humanitarian catastrophe” in Yemen.

The UN Humanitarian Office (OCHA) reports that more than 21 million Yemenis, or 80 per cent of the population, are in need of assistance as basic services collapse and hunger increases.

Airstrikes and ground fighting over the past three months have killed or injured thousands, and more than one million people have fled their homes for safer areas.
