A shooting in Saudi Arabia has claimed a fourth victim. A French teenager has died of his wounds a day after three other French nationals were killed in what appears to be a militant attack. It would be the first of its kind in three years. The men who were French expatriates living in Riyadh came under assault during a desert trip on Monday. They were part of a group of nine French citizens based in Saudi Arabia who had been visiting historic sites between the holy city of Medina and Tabuk, further north.
