The camps will be called "Vanguard of the Liberation."
Hamas doesn't try to hide that it is training children to be armed terrorists. The announcement states that "the camps will include military drills and skills, shooting live ammunition, scouting skills and sermons, as well as courses in civil defense and first aid."
Kids can register for the camps "at the nearest mosque or the nearest Qassam Brigades military site." Since the army sites are sprinkled liberally throughout residential areas, that makes it much easier to find a place to register.
Here's the flyer announcing the camps:
This is the third year of the camps. Here are some photos from last year's graduation ceremony (a full video is here.).
