STORY: Bayder told the Israeli Channel 13 News anchor that her aunt called hysterically, telling them to open Facebook, where the Palestinian militant who killed her grandmother had uploaded videos of her lifeless body in a pool of blood.The last time Bayder spoke to her grandmother was when she and her mother fled to a bomb shelter on Saturday morning (October 7) when rockets from the Gaza Strip started to pound Israel.She wanted to make sure the elderly woman, who resided by herself in the Gaza-border community of Kibbutz Nir Oz, was safe.It was only much later that she saw the Facebook video.
