Russian Premier League football team Anzhi Makhachkala has called for an end to "bigotry" in domestic football after its fans were abused by CSKA Moscow supporters.
Throughout CSKA's 1-0 home win over Anzhi on Saturday, CSKA fans shouted derogatory slogans about the Caucasus region. They also displayed a banner bearing the words "animal planet" with a modified Anzhi crest featuring an apparent anti-gay slur.
Anzhi fans typically hail from ethnic minority groups in the Caucasus.
In a statement headed "we demand football is protected from bigotry," Anzhi's general director Sergei Korablev asked law enforcement and football authorities to investigate the incidents.
Some CSKA fans say they were also abused by Anzhi supporters.
