Washington -- The US government does not possess independent confirmation of Ukrainian officials' allegations that Russia has sent military hardware to Ukraine, US Department of State Spokesperson Jen Psaki said. 

Speaking at a press conference on Nov. 7, Psaki said Washington has been informed by Kyiv that Russia has sent heavy artillery and tanks to Ukrainian territory, and if this information is confirmed, the US will denounce Russia’s new invasion of Ukrainian territory and would see it as yet another gross violation of the Minsk agreements, which were signed by both Russia and Russian-backed separatists.
