Rikad, a relative of Lt. Col. Mahmoud Hir al-Din, who was killed in 2018 in a secret IDF OP inside the Gaza Strip and who's name was only permitted for publication this morning, said:

"Some of us close to Mahmoud did not know at all that he was serving in the army, he wanted to be a school principal. 
Alongside the heroic work in the army he was inconceivably socially involved, there was not an event that was not there."
