Musk while on a tour of Kfar Aza heard details from Israel Defense Forces (IDF) troops of the massacres in the kibbutz. Israeli media has described it as a scene of "horrors"—one among more than 20 communities ravaged, where in some cases entire families were butchered. Musk later in the day said it was "it was jarring to see the scene of the massacre."

Musk heard briefings and personal stories both of tragedy and heroism, including the story of kidnapped Israeli-American toddler Avigail Idan, who turned 4 in captivity but was released Sunday as part of the third round hostage swap between Hamas and Israel. Her parents were murdered directly before her eyes, with accounts saying her dad was holding her when he was shot.
