The secret documents were found on the bodies of Hamas terrorists and include detailed maps alongside a systematic plan for the murder and kidnapping of hostages.

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.

The documents were found on the bodies of Hamas terrorists by Israeli first responders and shared with NBC News. They include detailed maps and show that Hamas intended to kill or take hostage civilians and school children.

One page labeled Top Secret outlines a plan of attack for Kibbutz Sa’ad, saying “Combat unit 1” is directed to “contain the new Da’at school,” while “Combat unit 2” is to “collect hostages,” “search the Bnei Akiva youth center” and “search the Da’at school.”

Another page labeled Top Secret Maneuver describes a plan for a Hamas unit to secure the east side of Kibbutz Sa’ad while a second unit controls the west. It says “kills as many as possible” and “capture hostages.” Other orders include surrounding a dining hall and holding hostages in it.

The detailed plan to attack Kfar Sa'ad is part of a trove of documents that Israeli officials are analyzing, according to one source in the Israeli army and one in the government. Surveillance video of Hamas terrorists entering a kibbutz on Oct. 7 shows tactics similar to those laid out in the documents obtained by NBC News.
