On February 21, Britain imposed sanctions on six people who were in charge of the Arctic penal colony where Russian opposition leader Alexei Navalny died last week.
The sanctioned people, including the head and five deputy heads of the penal colony, will be banned from entering the UK and their assets will be frozen, British Foreign Secretary David Cameron said.
"It is clear that the Russian authorities saw Navalny as a threat and repeatedly tried to silence him," Cameron said in a statement.
Cameron also said that Britain will hold responsible those who were responsible for the "brutal treatment" of Navalny.
Navalny was one of the leading critics of Russian President Vladimir Putin, and has been behind bars since 2021.
The United Nations special rapporteur for human rights in Russia, Mariana Katsarova, called on Moscow to conduct an independent investigation into Navalny's death, claiming that Navalny was held in very poor conditions in prison and was not provided with the necessary medical care.
The European Union has announced that it has invited the Russian chargé d'affaires to Brussels for an interview regarding the death in prison of opposition leader Navalny.
The US has announced that it will announce new sanctions against Russia due to Navalny's death.
On the other hand, on February 20, Putin promoted a high-ranking official of the prison where Navalny died.
The deputy head of the FSIN prison service Valery Boyarynev was promoted to lieutenant general of the Ministry of Internal Affairs, and the Kremlin said that the promotion was not related to Navalny's death.
