Twin brothers in Riyadh have stabbed their entire family, killing their mother and seriously injuring their father and elder brother. The 20-year-olds are reportedly loyal to Islamic State (IS, formerly ISIS/ISIL).
The twins, Khalid and Saleh Al Areeni, allegedly carried out the attack in their family home in the Saudi capital on Friday. According to investigators, the young men first stabbed their mother with a cleaver and sharp knives brought from the outside, before going after their father. They then chased their elder brother and stabbed him multiple times as well. Having thought the entire family was finished, the twins fled the scene in a stolen car.
