NEW: Minnesota woman Cindy Flash who "spent her life" advocating for Palestinian rights, was murdered by Hamas in her home.
Flash and her Israeli husband Igal were residents of Kfar Aza, a kibbutz in Southern Israel.
In a chilling final text message to her daughter, Flash said: "They are breaking down the safe room door. We need someone to come by the house right now."
Flash and her husband were murdered by Hamas in their safe room.
According to her daughter, Keren, Flash spent her life advocating for Palestinians in Gaza and had the "sweetest, biggest heart."
Devastating. RIP.
