NATO is "at war with Russia" over Ukraine, the spokesman for Russian President Vladimir President has said.
The comments by Dmitry Peskov come amid a spike in tensions between the alliance and Moscow following Poland's shooting down of Russian drones that entered the alliance member's airspace last week.
Polish Foreign Minister Radosław Sikorski said at the time that the drone incursion was a ploy by Russia to test the alliance.
Peskov said Monday it was "obvious" the alliance was "de facto involved in this war." Newsweek has contacted NATO for comment.
NATO has not directly entered the war, nor are its troops deployed to fight, but Peskov's comments echo those made by the Kremlin and its supporters who refer to the assistance Kyiv has received from NATO allies, including the U.S.
His comments highlight the friction between Moscow and NATO as concerns grow Russia is testing the alliance's resolve, with tensions heightened further after Romania said it had to deploy fighter jets in response to another incursion of its air space.
