Azerbaijan’s Culture Ministry on Sunday canceled Russian-linked cultural events amid diplomatic fallout over the reported killing of ethnic Azerbaijanis during police raids in the Russian city of Yekaterinburg.

The Foreign Ministry in Baku summoned Russia’s chargé d’affaires, Pyotr Volokovykh, on Saturday to protest what it called the “brutal killing” of two Azerbaijanis during Friday’s raids. The ministry said several others were seriously injured and nine were arrested.

Russia’s Foreign Ministry said Volokovykh had “offered the necessary explanations” to Baku after he was summoned. The ministry said those arrested were Azerbaijani-born Russian citizens accused of “past crimes,” but it did not mention the alleged deaths.

Police investigators in Yakterinberg said the raids targeted an “ethnic criminal group” linked to murders between 2001 and 2011. They claimed some of those who were arrested confessed to crimes, but gave no details on the number of arrests or reported deaths.

On Sunday, Azerbaijan’s Culture Ministry announced the cancellation of concerts, exhibitions and other events organized by Russian public and private groups. It cited what it described as “demonstrative targeted and extrajudicial killings” by Russian law enforcement based on ethnicity.
