Nine-year-old Mohammad Hadaf sustained severe injuries in an Israeli air strike during the 2014 Gaza War when he was six, leaving him paralysed, blinded, and unable to speak.
He finally succumbed to his wounds on December 6, last year.
"I hope nobody will ever have to experience what I did," said Saleh, Mohammad's father.
"I had to feed my son through a tube. When you see your son in this kind of pain, you also feel the pain with him," he told Al Jazeera.
