MOSCOW, March 17. /TASS/. Russia will do everything possible to make sure that Kiev regime’s crimes against humanity are not left unpunishable, Russian Foreign Ministry Spokeswoman Maria Zakharova said on Thursday.

"We will resort to all possible measures to make sure that these crimes against humanity are not left unpunishable," she told a news briefing.

The Russian diplomat said that the Kiev regime is immediately shifting the blame on Russians for all developments in the city of Mariupol, particularly the explosion at the Drama Theater, accusing the Russian military for an alleged air drop of a bomb on the facility.

"The blame for everything that happened in Mariupol, particularly in the context of the Drama Theater building bombing, the Kiev regime immediately tried to shift on the Russian troops who, allegedly dropped a bomb on the theater building," she said.

"This is a bold lie, the Russian Armed Forces are not bombing the cities and everyone is well aware of this, no matter how many video shots NATO compiled and no matter how many fake pictures are currently circulated, the truth will eventually emerge."

The Russian Defense Ministry announced late of Wednesday that militants of the Azov nationalist battalion blew up the Mariupol theater building, which they previously rigged with explosives. The Defense Ministry also debunked Kiev’s accusations of an airstrike on the theater building, where civilians could have been held hostage.

Russian President Vladimir Putin announced on February 24 that in response to a request by the heads of the Donbass republics he had made a decision to carry out a special military operation in Ukraine in order to protect people "who have been suffering from abuse and genocide by the Kiev regime for eight years."

The Russian leader stressed that Moscow had no plans of occupying Ukrainian territories and the operation was aimed at demilitarizing and denazifying Ukraine.

When clarifying the developments unfolding, the Russian Defense Ministry reassured that Russian troops are not targeting Ukrainian cities, but are limited to surgically striking and incapacitating Ukrainian military infrastructure. There are no threats whatsoever to the civilian population.
