The UN says civilians there are "at grave risk" and lacking food due to soaring prices. The internationally-recognised government is fighting back against the Houthis - or trying to - with the help of Saudi air strikes.

Caught in the middle of all this are fathers like Bajash, fighting to get help for their children. We saw another mother with a malnourished baby being turned away.

He found an ally, a forceful supervising nurse, Aisha Ragab, who had run from the war herself, back in 2018."

I feel for them," she said, "because I have already lived through the situation myself." Two beds could not be found, but Aisha was undeterred."

I will settle this by having the twins share a bed... so that we can save them.

By God, I will convince them [the doctors]." Within an hour the twins were lying on a single bed, their tiny bodies taking up little space.

Lina was feeding them sips of fortified milk from a tiny bottle, but Raad could not keep it down. He was cradled in her arms - his eyes wide and his cheeks sunken.

Asked if she thought her twins would rec over, Lina replied quietly, " God willing." Image source, Lee Durant/BBCImage caption, Raghad, like her brother, was diagnosed as having severe acute malnutritionAs we walked through the unit with its pink walls, some doors were padlocked shut.

There are 22 beds, but staff told us only 13 patients were admitted at a time - the most critical cases - due to the lack of international funding, staff, and equipment. That's a bitter pill to swallow for Dr Noor Mohammed, a harried young doctor."

It's sad to say, but we lose patients [because of the conditions]," she says. " We don't have good equipment like ventilation machines, and oxygen bottles," she adds.

" There are no good resources. A lot of laboratory investigations...

it's very hard to do them." A recent flare-up in fighting has left civilians in the firing line.

Even before the latest escalation, the UN calculated that half a million Yemeni children would suffer from severe acute malnutrition this year.

As one severely ill baby leaves, another arrives. And some of those discharged are back all too soon."

Sometimes a child comes back to us after a week, or two days," says Dr Mohammed. " Sometimes it is the same day.

They come back and we admit them and the story begins again." They return because parents cannot afford proper nutrition or vitamins or antibiotics."

Every child here, his parents came because they don't have anything," she tells me. " They don't have money or insurance.

They are here because they can't afford a private hospital." She does her best for them, she says, and she cries for them.

Image source, Lee Durant/BBCImage caption, Bajash and his other children were forced to sleep on the streetMany parents - like Bajash - are trying to outrun both war, and poverty. He is now a shepherd without a flock.

When he fled, he had to leave 10 sheep behind. They were his only livelihood.

As doctors monitored his twins, he cared for his three older children - all aged under five. They lingered on a bench in hospital reception without toys, bedding or baggage of any kind.

But they could not sleep there. So, they spent the night outside, on the street - one more family with war wounds that cannot be seen but will disfigure a generation.
