Кавказский эмират
Vilayat KBK suffered a split in August 2015, with Robert Zankishiev joining Caucasus Emirate commanders in other North Caucasus republics in pledging allegiance to the Islamic State of Iraq and the Levant (ISIL) leader Abu Bakr al-Baghdadi, while Zalim Shebzukhov led those who retained loyalty to the Caucasus Emirate. Both commanders were killed by Russian security forces in operations in November 2015 and August 2016 respectively.
