Kiev's involvement in the murder of war correspondent Vladlen Tatarsky will be yet another confirmation of the use of terrorist methods by Ukraine, Russian Foreign Ministry spokeswoman Maria Zakharova said.
"We believe that states and international organizations that really condemn terrorism and stand up for the safety of the work of journalists and bloggers are obliged to give a principled assessment of this blatant terrorist act," she added.
Zakharova's comment comes shortly after the Russian Investigative Committee announced that the murder of war correspondent Vladlen Tatarsky was being treated as a a terror attack.
The committee explained that based on the results of the preliminary investigation, the murder case has been reclassified under a more serious article as a terror attack.
According to the committee, there's evidence that the attack was masterminded in Ukraine.
"At the same time, Daria Trepova, who holds opposition views, is a supporter of the Anti-Corruption Foundation (the organization is recognized as extremist and banned in the Russian Federation)," the committee added.
The committee is now working to establish everyone involved in the crime, from perpetrators to organizers.
Earlier in the day, Russia's National Anti-Terrorism Committee announced that the explosion that killed Tatarsky on Sunday was plotted by the Ukrainian special services. The anti-terrorism committee revealed that Ukraine's special services recruited agents for the Donbass-born correspondent's killing from among supporters of the Anti-Corruption Foundation, a Russian non-profit founded by opposition figure Alexey Navalny.
Daria Trepova, a 26-year-old suspect in the terror attack that killed Tatarsky, was detained on Monday and exposed as a supporter of the Navalny group, the committee said.
Trepova was identified and detained after giving Tatarsky an explosive-ridden statuette as a gift at a St. Petersburg cafe on Sunday, just moments before the blast occurred.
Tatarsky (real name Maxim Fomin), who gained a massive following on Telegram and VK for his reporting on Russia's special military operation in Ukraine, was killed in the explosion, while 32 people were injured.
