The poster above is not a memorial to children tragically killed - it is a tribute to how wonderful these children are, both dead and alive, for attacking Israelis.
Al Resalah gushes, "In the squares of Al-Aqsa and Damascus Gate, and in every neighborhood and alley of the towns and camps of Jerusalem, a new generation is growing that sees in Israel nothing but an enemy that will only be defeated through resistance and jihad."
Other articles in Palestinian media are also praising the child terrorists.
And, still, silence from "human rights" NGOs, including those that are specifically meant to protect children.
