Putin says Moscow could target countries that supply Ukraine weapons 

At a recent news conference, he suggested that Russia might consider an "asymmetric" response to such attacks and the supply of long-range weapons to Ukraine. 

Putin warned that Western actions could further undermine international security and lead to "very serious problems," hinting that the Kremlin might provide long-range weapons to others to target Western interests.

“If someone thinks it possible to send such weapons to a war zone to strike our territory and create problems for us,” Putin said, “then why do we not have the right to send our weapons of the same class to those regions of the world where strikes can be made on sensitive facilities of the countries that do this against Russia?”

His remarks came in light of Ukraine's recent increase in capabilities. Not long ago, Ukraine's military used HIMARS ground-to-ground missiles for the first time during the war to hit a Russian system in the Belgorod region, which had been used to strike Kharkiv.

• On June 3, media reported that Ukraine targeted Russia’s S-300/400 battery stationed in the Belgorod region.
• Mykhailo Prytula, a retired SBU colonel and military counterintelligence expert, believes that the destruction of S-300/400 systems in the Belgorod region is a result of the US allowing Western weapons to strike at Russia.
