Their names were Anas and Saad, and I don't think their surnames are published. They were both killed on July 20, 2014.
Here they are:
What is interesting is that the article says that they were born on December 5, 1996 - which means that they were 17 when they were killed - and considered "children" by NGOs. Furthermore, we are told that they joined Islamic Jihad's Al Quds Brigades in late 2012, which would have been around their 16th birthdays.
Of course these martyr photos and videos were created months before they were killed.
I noted last year that 70% of th e children killed in Gaza between the ages of 9-17 were boys. The ratio goes up the older the teens are, from 62% of those 9-11 to 79% of those between 15-17. Given that we have evidence (same link) of children as young as nine being used by terror groups, a significant number of the "children" killed in Gaza must have been helping out Hamas or other terror groups.
The Meir Amit ITIC, in their latest report on how Gaza terror groups recruit children, says "An examination of the names of Gazan fatalities in Operation Protective Edge indicated adolescents who served in the military-terrorist wings of the terrorist organizations in the Gaza Strip. The extensive recruitment of young men and the intention to use them as auxiliary forces for the regular military-terrorist units is liable to increase the number of those killed and wounded in future confrontations between the terrorist organizations and the IDF, serving Hamas as propaganda material to use against Israel."
It may be far worse than that. Documentary filmmaker Pierre Rehov wrote last year in Gatestone:
When making one of my documentaries, the Palestinian who was leading my crew offered me a scoop. As I was French, he trusted me to be on the Palestinians' side. "You know," he said, "what pays well? When an Israeli soldier kills a child. Are you interested?" he continued. "We can arrange that. For $10,000, I can organize everything." Was he talking of a staging, or the real killing of a child? I did not dare to ask. I still nurture hope, despite the facts, that people would not willingly sacrifice children just to promote a show.Sacrificing children is part of thee war strategy for these sick organizations.But that idea is so heinous that Westerners just don't want to believe it.
