The Counter Extremism Project (CEP) reports weekly on the methods used by extremists to exploit the Internet and social media platforms to recruit followers and incite violence. Last week, CEP researchers located a pro-ISIS propaganda video on Telegram and other websites celebrating attacks in Egypt’s Sinai region, another pro-ISIS video encouraging attacks in Europe, the 21st issue of a pro-ISIS web magazine, and numerous accounts on Meta-owned Instagram posting pro-ISIS propaganda.
