Yemeni children under siege and malnutrition

The conflict has also caused what the UN says is the world’s worst humanitarian disaster.

Four million people have been forced to flee their homes and more than 20.7 million – 71% of the population – are in need of some form of humanitarian assistance or protection for their survival.

They include 5 million who the UN says are on the brink of famine, and almost 50,000 who are already experiencing famine-like conditions.

An estimated 2.3 million children under the age of five are acutely malnourished, including 400,000 who are at risk of dying without treatment, according to the UN.

But with only half of the country’s 3,500 medical facilities fully functioning and 20% of districts having no doctors, almost 20 million people lack access to adequate healthcare.

One out of every two people also do not have access to safe water.
