Save the Children has said this now brings the total number of children in Yemen at risk of famine to 5.2 million.

More than two-thirds of the country’s population “don’t know where their next meal is coming from”, the charity added.

A weakening currency and collapsing economy is the result of ongoing conflict, Save the Children explained.

Helle Thorning-Schmidt, chief executive of Save the Children International, said in a statement: “Millions of children don’t know when or if their next meal will come.

“This war risks killing an entire generation of Yemen’s children who face multiple threats, from bombs to hunger to preventable diseases like cholera.”

Food prices in the country have increased by an average of 68% since 2015, while fuel commodities, like petrol, diesel and cooking gas has increased by 25% since November last year and this month.

Another threat comes from fighting around the key port city of Hudaydah, which is the main lifeline for almost two-thirds of the population.

Because of the war, teachers and public servants have not been paid their salaries on time and some people have not received wages for almost two years.
