Fourteen-year-old Fadel al-Naji used to be a keen soccer player but is now largely confined to his home in Gaza City since both legs were severed in an Israeli drone attack in September.

He sits sullenly on a couch with one hollow pant leg dangling and the other tucked into his waist beside his 11-year-old brother, who lost an eye in the same strike.

“He has become withdrawn and isolated,” said his mother Najwa al-Naji, showing old videos of him doing kick-ups on her phone. “It is as if he is dying slowly, and I wish that they ​would fit him with prosthetic limbs.”
