Maps and documents recovered from the bodies of Hamas attackers reveal a coordinated plan to target children and take hostages inside an Israeli village near Gaza.

Documents exclusively obtained by NBC News show that Hamas created detailed plans to target elementary schools and a youth center in the Israeli kibbutz of Kfar Sa’ad, to “kill as many people as possible,” seize hostages and quickly move them into the Gaza Strip.

The attack plans, which are labeled “top secret” in Arabic, appear to be orders for two highly trained Hamas units to surround and infiltrate villages and target places where civilians, including children, gather. Israeli authorities are still determining the death toll in Kfar Sa’ad.
