So-called Islamic State group (IS) has shifted its propaganda distribution to the secure mobile messaging app Telegram from Twitter, where its accounts have been repeatedly shut down over the past year.
IS and other jihadist groups appear to be exploiting new functionality introduced by the app last month, which allows users to broadcast their messages to an unlimited number of members via their own Telegram "channel".
On 26 September, just four days after Telegram trumpeted the launch of its new "Channels" tool, IS media operatives on Twitter started advertising the group's own channel dubbed Nashir, which translates as "Distributor" in English.
It has already amassed more than 4,500 subscribers.
Since then, IS propaganda has started appearing first via Telegram, often several minutes before being posted to Twitter.
Since then, Twitter has remained the group's preferred platform. But it has been caught up in a cat-and-mouse game with the Twitter administration, which has also led to its quasi-official, non-branded accounts routinely suspended.
