Attack on Russian opponent in Vilnius raises fears of Kremlin infiltrations in Baltic countries. Estonia, Latvia and Lithuania have repeatedly warned of Moscow's intentions to carry out destabilizing actions on their territory.
The three Baltic republics have arrested dozens of Russian citizens in the last two years accused of spying or preparing attacks on the orders of the Kremlin. In recent weeks they have expressed concern about the possibility that Russia dares to attack them directly, or even invade a small portion of their territory, to test NATO.
