On 23 September 2015 Chatham House’s Russia and Eurasia Programme joined with the University of Birmingham to host a roundtable discussing fighters from the North Caucasus and Central Asia and the Syrian civil war. The first session addressed the impact of fighters from the former Soviet Union region on the war in Syria, logistical issues, and Russian views of the Syrian conflict. The second session concentrated on the insurgency in the North Caucasus, including its links to the global jihad and the implications of returnees from Syria. The meeting was held under the Chatham House Rule,1 and the views expressed are those of the participants. The following summary is intended to serve as an aide -memoire to those who took part, and to provide a general summary of discussions for those who did not.
