Caucasus Emirate
In 2014, Rustam Asildarov and a number of other senior Caucasus Emirate commanders announced their defection to the Islamic State of Iraq and the Levant (ISIL), swearing an oath of allegiance to its leader, Abu Bakr al-Baghdadi. Both, Suleimanov and Caucasus Emirate leader, Aliaskhab Kebekov, condemned this as a betrayal.
