Who?
Hamas, that''s who.
You are doubtful? Read:
"...A similarly cavalier approach to child labor and tunnel fatalities damaged the movement’s standing with human-rights groups, despite government assurances dating back to 2008 that it was considering curbs. During a police patrol that the author was permitted to accompany in December 2011, nothing was done to impede the use of children in the tunnels, where, much as in Victorian coal mines, they are prized for their nimble bodies. At least 160 children have been killed in the tunnels, according to Hamas officials.”
And that''s from a ''Palestinian'' journal.
