ISIS militants have released another execution video, this time showing the beheading of 21 Egyptian men held captive in Libya.
Those women were both wives of Coptic priests who disappeared and reportedly converted to Islam. Eventually, Egyptian police discovered them and returned them to the custody of the church.
