Turkish lawmakers passed a bill late Wednesday that includes restricting access to social media platforms for children under 15, state media reported. The legislation is the latest in a global trend to protect young people from dangerous online activity. Its passage comes a week after a 14-year-old boy killed nine students and a teacher at a middle school in Kahramanmaras, southern Turkey, in a gun attack. Police are investigating the online activity of the perpetrator, who also died, in a bid to uncover his motivation for the attack.
