MOSCOW, March 2 (Sputnik) - Russia's response to new US sanctions will not necessarily be symmetrical, Washington's decision is a triumph of the absurd and a hostile attack that will not affect Moscow's policy, Russian Foreign Ministry spokeswoman Maria Zakharova said on Tuesday.

The US followed EU suit earlier in the day to impose sanctions against Russia over alleged production of biological and chemical weapons. The list includes 14 organizations and a number of individuals. Russia has repeatedly denied all US allegations related to the Navalny case, saying Western countries ignored Moscow's requests for substantiating materials.

"The absurd triumphs when the reason for the imposition of sanctions is declared to be a deliberately arranged provocation with the alleged 'poisoning' of Navalny with some 'chemical weapons.' All this is just an excuse to continue open interference in our internal affairs. We do not intend to put up with this. We will react on the basis of the principle of reciprocity, not necessarily symmetrically," Zakharova said in a commentary.

"The US administration has undertaken a hostile anti-Russian attack, announcing, in a duet with the European Union, the next sanctions measures to 'punish Moscow,'" she said.

Earlier, the United States imposed individual sanctions, as well as trade and visa restrictions, targeting senior Russian officials, over the alleged poisoning of jailed Russian vlogger Alexei Navalny.
