​​​​​​Al-Qassam's official website shared details on Nahal Oz operation which was carried out six years ago during the 2014 aggression on the Gaza Strip. The resistance fighters used one of the tunnels to attack an observation post near Nahal Oz settlement. The fighters killed 10 Israeli soldiers from a short distance amid intensive flight of drones. The soldiers were too shocked to fight back, so all the fighters returned to the base without injuries.
