Vladlen Tatarsky, a well-known military blogger and supporter of the war in Ukraine, was killed in an explosion in a cafe in St. Petersburg on Sunday. The blast also injured 30 people, including 19 who were hospitalized. Some reports suggest that a bomb was embedded in a bust of Tatarsky that was given to him as a gift. A woman named Darya Tryopova was arrested on suspicion of involvement in the bombing. She had previously been detained for participating in anti-war rallies. The patriotic Russian group that organized the event in the cafe said that it had taken security precautions but that they “proved insufficient.” Investigators have opened a murder investigation, but it remains unclear if Tatarsky was the intended target of the blast. Tatarsky had gained popularity since the start of Russia’s “special military operation” by providing analysis and commentary. He had more than half a million followers on Telegram and had written several books. While he was pro-war, he had sometimes been critical of Russia's setbacks in Ukraine. This tragedy raises important questions about the safety of journalists and political opponents in Russia.
