 Israeli troops uncovered a tunnel system and southern Gaza were about 20 Israeli hostages were held in inhumane conditions, including a five-year-old who drew hopeful pictures while in captivity. The footage show off a vast tunnel spanning more than half a mile below the home of a Hamas commander in Kanyunas. Southern Gaza's largest city of the warren of tunnels beneath contained, said the Israel Defense Forces, something more sinister than they had found in the past a set of cells where hostages were kept, several flights of stairs cut down into the clay, leading us to a steel padlocked gate from there, the tunnel zigs and zags for dozens of yards. Each offshoot is connected by a joint, many of which had been booby-trapped, that one has to crabwalk to get through as Israeli soldiers still guarded the unexplored tunnel offshoots. Everything appears to be connected to something down there.
