Young's family, including his two brothers and two sisters, paid tribute.
In a statement on Facebook, the family said: “We’re heartbroken to share that our little brother Nathanel Young was tragically killed on the Gaza Border yesterday.”
Nathanel’s brother, Eliot Young, added to the BBC: "Nathanel was full of life and the life of the party. He loved his family and friends and was loved by everyone.
"He loved music and was a talented DJ, DJing both on base and at Benji's House, the lone soldier house where he was living."
His death comes after 26-year-old Jake Marlowe, who went to the same London school as Young, was reported missing while providing security at a music festival near Kibbutz Re'im, close to the Gaza border.
