On Wednesday, the Russian Foreign Ministry warned against the use of US or NATO long-range weapons by Ukrainian forces in bombing Russian territory, saying, The consequences would be more serious."
Konstantin Gavrilov, head of Russia's delegation to the Vienna talks on security and arms control, said: "If the Ukrainian forces used American rocket launchers or other long-range NATO weapons to bombard the Russian territory, the consequences will be more serious."
Notably, Ukraine has claimed to have eliminated 40,000 Russian occupiers since the beginning of Russia's invasion.
NATO began sending additional troops to its eastern flank following Russia’s previous invasion of Ukraine in 2014 when it seized the Crimea region. Moscow has since supported separatists in eastern Ukraine in a bloody war against the Kyiv government.
On February 11, U.S. President Joe Biden ordered the deployment of an additional 3,000 U.S. soldiers to Poland. A Pentagon statement said the troops would join some 1,700 soldiers who arrived in Poland at the start of the month.
"All told, this 5,000 additional personnel comprise a highly mobile and flexible force, capable of multiple missions. They are being deployed to reassure our NATO allies, deter any potential aggression against NATO’s eastern flank, train with host-nation forces, and contribute to a wide range of contingencies," the Pentagon statement said.
