BURAIDA, Saudi Arabia — The men were not hardened militants. One was a pharmacist, another a heating and cooling technician. One was a high school student.
They were six cousins, all living in Saudi Arabia, all with the same secret. They had vowed allegiance to the Islamic State — and they planned to kill another cousin, a sergeant in the kingdom’s counterterrorism force.
And that is what they did. In February, the group abducted Sgt. Bader al-Rashidi, dragged him to the side of a road south of this central Saudi city, and shot and killed him. With video rolling, they condemned the royal family, saying it had forsaken Islam.
