Russian side Anzhi Makhachkala were asked by UEFA on Wednesday to find an alternative stadium for their Europa League home fixtures due to concerns over security in Dagestan and the North Caucasus.
The European football governing body's Emergency Panel decided that due to the "security situation" in the area that "no UEFA competition match is allowed to be played in this region during the 2013/14 season".
Anzhi, who achieved their best finish with third place in last season's championship, have consequently been given until June 30 to propose another venue for their home matches.
Also factored into the panel's decision were "warnings issued by various governments", with the ruling to remain in place for subsequent seasons until further notice.
One person was killed with 13 injured in a suicide bombing in Dagestan on May 25, five days after a twin blast in the restive region claimed four lives.
