TEHRAN, Iran (AP) — Iranian prosecutors have filed criminal charges against the CEO of the popular encrypted messaging app Telegram, a semi-official news agency reported Tuesday. They allege that the service, which is used to spread uncensored news and political opinions, is rife with extremist propaganda and child pornography. Telegram CEO Pavel Durov said "the real reasons" for the charges were far different, suggesting this newest controversy merely represents the latest back-and-forth between the government and the app, which millions of Iranians use.
