Berlin: The creators of a popular messaging app called Telegram say they are acting to stop the Islamic State group from distributing propaganda to a wide audience through the service.
In a statement on Wednesday, Telegram said it had blocked 78 IS-related channels over the past week and was making it easier for users to report objectionable material.
Berlin-based Telegram said the move would only affect public channels and automated response systems called 'bots.'
Messages between individuals and group chats that can include up to 200 users would not be affected.
Telegram uses strong encryption that makes it all but impossible for security services to intercept private messages between individuals or members of a group.
