Al-Hilu, a father of six daughters and four sons, began to cry and attempted a smile as he remembered Mahmoud: He is the youngest. Myself, his mother and all other family members all liked and pampered him, but now he is lost and now his smile is no longer with us.

One of Mahmoud's favorite things was watching wrestling on TV and he was a fan of the wrestler John Cena, to the extent that he used to imitate him often by wrestling with his brothers and sisters and even with myself, al-Hilu recalled.

Mahmoud's father described to The Electronic Intifada how his son was hit.

After I came back from afternoon prayer, I saw my uncle Yasser Hamad and his grandson Yasser Ahed bleeding in front of this door, he said outside of the family's home.

I tried to aid them and I was shocked to see my son Mahmoud laying near that fence bleeding and his abdomen had been ripped open, al-Hilu said as he gestured toward the locations where the three Israeli tank shells landed.

In addition to Mahmoud, three other persons were killed in the attack: Muhammad Saber Harara, 19, according to the Palestinian Centre for Human Rights, as well as Yaser Hamad al-Hilu, 51, and his grandchild Yasser Ahed al-Hilu, 15. Another 11 civilians, including eight children, were injured, three seriously.
