Twin brothers, 18-years-old, in Saudi Arabia chased and stabbed their younger brother and then returned home to kill their mother and father because they were all critical of ISIS. The brothers were arrested by police after attempting to flee the scene.
PressTV further reports that some statements suggest that the mother was beheaded.
Saudi Arabia has been plagued by small scale terrorist attacks inspired by the ISIS. For example, weeks ago, ISIS released a video showing Islamic State sympathizers carrying out a drive-by assassination on Saudi Arabian Colonel Kitab Majid al-Hammadi in al-Dawadmi, west of Riyadh.
ISIS has claimed the area of Riyadh as their “Najd Province.” It is one of two provinces ISIS claims in the region, the other being Wilayat Hejaz.
