In a statement, Stephen O'Brien, the UN Emergency Relief Coordinator and Under-Secretary-General for Humanitarian Affairs underscored that in addition to wrecking the country's economy, killing thousands and displacing millions, the fighting has brought Yemen to the brink of a famine.

“During my third visit to Yemen only weeks ago, I saw the terrible and terrifying evidence of looming famine,” said O'Brien.

“In the hospital ward, the complete stillness of the tiny malnourished child whose eyes focus on nothing. The grim realization that these patients were the fortunate ones who could access a hospital and might survive.”

Underscoring that UN and its partners are already providing life-saving assistance in all of Yemen's 22 governorates, reaching almost 6 million people every month, O'Brien urged parties to the conflict to expedite immediate, timely, and unimpeded humanitarian access as well as facilitate commercial activities – critical to reversing prevailing massive food insecurity and ensuring that people's basic needs can be met.

Nearly 19 million Yemenis – over two-thirds of the population – need humanitarian assistance and, according to UN Office for Coordination of Humanitarian Affairs (OCHA), seven million are facing starvation.

“Most of all, the Yemeni people need the parties to commit to political dialogue, or this man-made crisis will never end,” noted O'Brien.

“In the meantime, together we can – we must – avert this famine, this human catastrophe.”

Number of children injured, recruited in conflict nearly doubled in one year – UNICEF

As with most crises, it is the children who are bearing the brunt of the suffering.

Families are having to resort to “extreme measures” to support their children as coping measures have been severely eroded, turning Yemen – the poorest country in the region – into one of the largest food security and malnutrition emergencies in the world, noted United Nations Children's Fund (UNICEF) in a new report, Falling through the Cracks on Monday.

According to UN verified data, in the past year alone, the number of children killed increased from 900 to more than 1,500; those injured nearly doubled from 1,300 to 2,450; children recruited in fighting neared 1,580 (compared to 850 last year); and 212 schools were attacked (up from 50 last year).

Also, Yemen's health system is on the verge of collapse, leaving close to 15 million men, women and children with no access to health care. This is all the more concerning given an outbreak of cholera and acute watery diarrhoea in October 2016 that continues to spread, with over 22,500 suspected cases and 106 deaths.

“The war in Yemen continues to claim children's lives and their future,” said Meritxell Relaño, UNICEF Representative in the war-torn country.

“We need to act now to pull families back from the brink. The risks for generations to come are extremely high.”
