Dissident Leonid Volkov, a close collaborator of the Russian opposition leader Alexei Navalny, died a month ago in a Siberian prison. Volkov was ambushed by at least two people near his home in Vilnius, the capital of the Baltic Republic, a member country of the European Union.

The police and their elite anti-terrorist unit are investigating what happened, but the Lithuanian president, Gitanas Nauseda, has already clearly pointed out the main suspect of being behind the criminal action.
