Driven from Twitter by tougher anti-terror regulations, Islamic State and its followers have increasingly turned to private messaging app Telegram.
And Western nations have more than taken notice.
With millions of IS loyalists communicating with one another on Telegram and spreading their message of radical Islam and extremism, France and Germany last week said that they want a continent wide effort to allow for a crackdown on Telegram.
“Encrypted communications among terrorists constitute a challenge during investigations,” France and Germany said in a statement. “Solutions must be found to enable effective investigation… while at the same time protecting the digital privacy of citizens by ensuring the availability of strong encryption.”
