If war continues, famine could engulf the country in the next three months, with
12 to 13 million civilians at risk of starvation, according to Lise Grande, the
agency’s humanitarian coordinator for Yemen.
She told the BBC: "I think many of us felt as we went into the 21st century that it was unthinkable that we could see a famine like we saw in Ethiopia, that we saw in Bengal, that we saw in parts of the Soviet Union – that was just unacceptable.
"Many of us had the confidence that would never happen again and yet the reality is that in Yemen that is precisely what we are looking at.”
Last month Save the Children warned the fighting was turning into a "war on children” with thousands suffering life-changing injuries in the attacks.
On a visit to Yemen the charity’s CEO, Helle Thorning-Schmidt, warned attacks on schools and hospitals were on the rise, with children on the frontline of violence and medics unable to cope with the influx of the wounded.
Meanwhile the country’s currency has collapsed and food prices have doubled in the last month, fuelling the threat of famine.
