Russia has added former Prime Minister Vladimir Kasyanov to its list of terrorists and extremists. The move comes as part of a broader effort by Moscow to restrict the activities of individuals and organizations deemed to be a threat to state security. Economists Sergei Guriev and Novaya Gazeta Europe editor-in-chief Kirill Martyn, who were also added to the list, are known for their critical views of the Russian government and their roles in advocating for democratic reforms within the country.
