The military wing of Hamas, al-Qassam Brigades has published a statement on their website announcing the death of their 19-year-old member Ramadan Suhail Shehadeh Awwad, supposedly from drowning.
I am guessing if he did drown, it was either because he tried to identify himself by his name when screaming for help, or he was carrying his gun at the time.
The real tragedy here is how one so young was brainwashed into dedicating his life to murdering innocent people.
