An assassination attempt on Vladimir Osechkin, the founder of Gulagu.net, was thwarted in France. French intelligence agencies arrested a group of individuals suspected of plotting the murder of the Russian opposition leader. Three natives of Dagestan were among those detained.

Two participants of the rally in memory of the victims of the Caucasian War filed complaints with the Supreme Court of the Kabardino-Balkarian Republic. Zuber Euaz and Timur Nakhushev appealed against the administrative arrest, considering it illegal.
The day before, it became known that most of the eight participants of the rally left the special detention center in Nalchik after serving their arrest. Earlier, the public organization "Kabardino-Balkarian Regional Human Rights Center" appealed to the head of the republic Kazbek Kokov with a request to release the detainees.
On May 21, a rally was held in Nalchik in memory of the victims of the Caucasian War and those who died for the independence of the Circassian people. At least two thousand people took part in the rally. Initially, many of them were called in advance by employees of the Center for Combating Extremism of the Ministry of Internal Affairs with an offer to come to the department to receive a warning about the "inadmissibility of actions that create conditions for committing an offense." According to human rights activists, at least eight demonstrators were detained and subjected to administrative arrest. They were accused of participating in an unauthorized event and blocking roads.
The Caucasian War (1817–1864) is a general name for the military actions of the Russian Imperial Army associated with the annexation of the North Caucasus to the Russian Empire and its military confrontation with the mountain peoples. After the war, the Adyghe (Circassians) were forced to leave their homeland en masse.
