“Salahuddin Shishani, the former emir of the Jaish al Muhajireen wal Ansar who now leads a group of jihadists from the Caucasus in Syria, swore allegiance to the new leader of the Islamic Caucasus Emirate. Shishani and his deputy, Abdul Karim Krymsky, were removed from the leadership of Jaish al Muhajireen wal Ansar (the Army of the Emigrants and Helpers, or Muhajireen Army) just last month.”

“Shishani announced his pledge to Muhammad Abu Usman in a short video, nearly three minutes long, that was released by Akhbar Sham, a Russian-language website that previously promoted Jaish al Muhajireen wal Ansar’s activities and leaders in Syria. The video was also published by Kavkaz Center, which supports the Islamic Caucasus Emirate.” (Coordination Center)
