But on Tuesday, Washington’s role in the war in Ukraine was put under scrutiny after Moscow accused the US of supplying targeting information used by Kyiv to conduct long-range missile strikes.
It is feared Russia’s claim could impact the White House’s aid capabilities.
Russia’s defence ministry said Washington was “directly involved” in the war and had passed on intelligence that had led to the “mass deaths of civilians”.
The US was responsible for rocket attacks by Kyiv on populated areas in the eastern Donbas and in other regions, the ministry said in a statement.
It added: “All this undeniably proves that Washington, contrary to White House and Pentagon claims, is directly involved in the conflict in Ukraine.”
While the US has proudly provided security assistance to Ukraine, it strongly denies it is a participant in the conflict or is at war with Russia.
