The audio clip was distributed on Monday on ISIS's channel on Telegram, an encrypted messaging application. It was attributed to the militant group's official spokesman, Abi al-Hassan al-Muhajer.
The authenticity of the recording could not be independently verified, but the voice was the same as a previous audio message purported to be from the spokesman.
"To the brethren of faith and belief in Europe, America, Russia, Australia, and others. Your brothers in your land have done well so take them as role models and do as they have done."
