KAZAN, May 31. /TASS/. The bravery, heroism and self-sacrifice being demonstrated by militiamen and Russian troops in the Donbass republics show that the truth is on Russia’s side, the country’s Security Council Secretary Nikolay Patrushev said on Tuesday.

"The bravery, heroism and self-sacrifice being demonstrated by local militiamen and Russian servicemen in the Donetsk and the Lugansk People’s Republics are proof that the truth is on our side," Patrushev said addressing a meeting in Kazan on national security in the Volga region.

The Russian security official also emphasized that Russia would surely attain the goals of its special military operation.

"Russia was forced to preemptively launch its special military operation as long as its well-grounded security guarantees were being totally ignored amid plans by the Kiev regime to renounce its non-nuclear status and join NATO, reconnaissance data showing preparations for military activities in the Donbass republics and an attack on Russia and other threats," he added.

Patrushev pointed to documented proof obtained in the course of the special operation of the plans by Kiev and of biological military activities that had been run in Ukraine under foreign sponsorship and control.
