The war in Yemen has hit hardest those who are least responsible – children.
In 2016 Abdullah, his parents and his eight siblings left their home in Harad, a town near the Saudi border in northwest Yemen, because of shelling.
They moved in with his uncle nearby but on a September night, just before the Eid al-Adha religious holiday, an airstrike hit.
"The strike was very sudden and felt like someone pulled my leg, but then I realized it was blown off," Abdullah said. Two of his cousins were killed in the same strike.
The United Nations says tens of thousands of people have been killed and millions displaced in Yemen's civil war, which pits the Iran-aligned Houthi movement against a Saudi-led coalition backed by the West.
Thousands have lost limbs and have no access to prosthetics.
Abdullah was rushed to Abs, in the province of Hajjah, where he was treated in hospital.
Two years after he lost his leg, the Abs Development Organisation for Women and Children, a humanitarian operation, opened and arranged for him to travel to the capital Sanaa to be fitted with a prosthetic.
"I had to stay in bed for two years, but when the Abs Organisation finally opened, they installed a prosthetic leg for me and thank God now I can walk wherever I want," Abdullah said, sitting down with his prosthetic removed revealing the stump below his left knee.
The prosthetic is a basic plastic calf and foot pulled over his knee with what looks like nylon tights.
Wearing his green flip-flops, Abdullah is now able to collect water from the tank and dig holes for tent stakes in the Internally Displaced Persons (IDP) camp where the family now lives, near the town of Khamis.
He hopes to be reunited with his father, who recently left to look for work, and also to resume his studies.
"Before my leg was blown off, I had finished grades one and two. But since then there wasn't a school close by and even right now, I don’t go to school."
Eighty per cent of people in Yemen, the Arabian Peninsula's poorest country, need humanitarian assistance and millions are on the brink of starvation.
Of some seven million school-age children, two million are out of school completely, the United Nations says.
Non-payment of teachers' salaries has also impacted the availability and quality of education for Yemen's children.
