Russian President Vladimir Putin said during a televised meeting on Wednesday that there are grounds to believe that Western special services are involved in what he called acts of “sabotage” and “acts of terrorism” by Ukraine. Reported by Reuters.

At a Kremlin Security Council meeting with leaders of four Ukrainian regions annexed by Moscow last year, Putin accused Ukraine of committing crimes against Russian administrators, security officials, journalists and teachers with the help of Western intelligence services.

Russia often accuses Ukraine of killing civilians during bombings in parts of Ukraine controlled by Russia and in Russian border regions near Ukraine.

“There is every reason to say that the resources of third countries, Western special services, are engaged in the preparation of such subversive and terrorist acts,” Putin said.

Putin’s comments came three days after Russian military blogger Vladlen Tatarsky, whose real name is Maxim Fomin, was killed in an explosion in St. Petersburg that Russian officials blamed on Ukraine.

On Tuesday, the Russian prosecutor’s office formally charged Daria Trepova with terrorism in connection with the murder of military blogger Vladlen Tatarsky in St. Petersburg.

Tatarsky was killed in an explosion on Sunday at a St. Petersburg cafe owned by the leader of Wagner’s mercenary group Yevgeny Prigozhin.

Vladlen Tatarsky, a staunch supporter of Russia’s invasion of Ukraine, was killed by an explosive device hidden in a plaster statue given to a military blogger by an attendee at an event where Tatarsky, who called for the “total destruction of Ukraine,” had intended to speak about his experience a military reporter at the front in eastern Ukraine. As a result of the explosion, about 30 people were also injured.

Russian security forces detained Daria Trepova, who was identified as the person who handed over the corresponding statuette.
