Russian President Vladimir Putin criticized the West for providing long-range weapons to Ukraine, warning that Moscow could arm other countries to attack Western targets in response.
Putin's comment came after several Western countries gave Ukraine permission to strike Russian territory.
Putin argued that if the West can supply weapons to Ukraine for attacks on Russia, then Russia has the right to supply similar weapons to regions where Western countries' sensitive facilities are at risk.
Putin hinted at an asymmetric response, but did not provide further details.
Putin, 71, dismissed allegations of Russia planning to attack NATO members as "bollocks," insisting there are no imperial ambitions.
He criticized Western arms deliveries to Ukraine, particularly Germany's, as a "negative step" and a threat to Russian-German relations.
Putin reiterated that Russia did not start the war in Ukraine, instead blaming a pro-Western revolution in 2014.
Putin denied that Russia initiated the war in Ukraine and refused to disclose Russian military casualties, stating that the ratio of Russian to Ukrainian losses is one to five.
He emphasized that no one in the West wants to remember how the conflict started.
The discussion of military casualties is a sensitive topic in Russia, with criticism of the conflict and spreading false information about the army being punishable by up to 15 years in jail.
Putin indicated Russia's readiness to help investigate the killing of an AFP video journalist in Ukraine, likely caused by Russian rocket fire.
Putin expressed readiness to help in an investigation regarding a person who died in a warzone, but acknowledged the challenge of doing so.
He downplayed the significance of a US presidential victory for Russia's relations with the US.
Putin criticized the criminal charges against former US President
Donald Trump as politically motivated and damaging to the US's reputation as a leading democracy.
Trump was the first former US president to be convicted of a crime, in a case involving hush money payments.
President Trump has praised Russian President Putin as a "smart guy" and mentioned that the two countries are in "constant contact" regarding a potential prisoner exchange.
This exchange could free jailed US journalist Evan Gershkovich, who was arrested on espionage charges in Russia last year.
Putin stated that the decision on the exchange would be made based on reciprocity.
