In 2004 Hamas sent masked collectors into the streets and Mosques of Gaza to gather contributions for the resistance above is a picture of a collection box used in that campaign.
The photo shows a child contributing money. The object on top of the box is a live hand grenade (Israeli TV Channel 2, April 10, 2004).
During that campaign, magazines, bullets, grenades and explosives were also donated.
That said, the following article caught my eye.
Hamas’ Al Aqsa Television
Normally I am for freedom of the press, but since Hamas’s means to its political ends are questionable, is this to be a vehicle of information or a means to spread violence?
