Russian investigators today charged the 26-year-old Daria Trepova terrorist attack charges in connection with the killing of blogger and war supporter Vladlen Tatarsky in a bomb blast in St. Petersburg.

Tatarsky, staunch supporter of military intervention in Ukraine, whose real name was Maxim Fomin, was murdered on Sunday in a cafe where he was about to speak.

Russia’s Investigative Committee, which deals with major crimes, said it had indicted Trepova for committing “a terrorist act by an organized group that intentionally caused death.” The charges carry up to 20 years in prison.

Her statement states that Trepova acted on instructions from people working on behalf of Ukraine.

Russia’s health ministry said 40 more people were injured in the blast, of which 25 remained hospitalized as of this morning.

Trepova was transferred from St. Petersburg to Moscow, where investigators were to ask the Basmani court, located in the district of the same name, for her pretrial detention.

Video footage from the event at the St Petersburg cafe showed Tatarsky showing off the statuette to his audience before it exploded.

Russia’s National Counter-Terrorism Committee today accused Ukrainian intelligence services of orchestrating the assassination with the help of supporters of jailed Kremlin critic Alexei Navalny, a possible reference to the fact that Trepova had once enrolled in an anti-Kremlin tactical voting scheme promoted by the movement of Navalny.

An adviser to the Ukrainian president said the attack was a result of internal conflicts in Russia.

Her husband Trepova told investigative journalism website The Insider on Monday that he believed she had been set up and that he did not know the statuette contained explosives.

Tatarsky himself had fought in Ukraine with separatist forces and had also served time in Ukraine for a bank robbery.

Last year, in a video taken at a Kremlin ceremony to celebrate Russia’s unilateral annexation of four Ukrainian regions, Tatarsky said Russia should “kill everyone” and “rob everyone” in Ukraine.
