A Russian official warned last week that the efforts by the U.S. and other western nations to arm Ukraine against Russia’s invading forces puts them at risk of a “direct military confrontation” with Russia.

Russian Ambassador to the U.S. Anatoly Antonov told Newsweek late Friday that “Western states are directly involved in the current events as they continue to pump Ukraine with weapons and ammunitions, thereby inciting further bloodshed.”

Antonov’s comments come after around a month and a half of fighting between Russian invasion forces and Ukrainian defenders. Even before the fighting began, the U.S. and other western nations had sent hundreds of anti-tank and anti-aircraft launchers to Ukraine. The U.S. and members of the North Atlantic Treaty Organization (NATO) have continued to send weapons to Ukraine throughout the ongoing fighting.
