Thank you, in the post it says:

Anti-war demonstration in front of the USA embassy Kiev, Ukraine.

“Happening now - an antiwar rally in Kiev in front of US embassy in Ukraine. The protesters demand from US to stop intereference in Ukraine and pushing it to war with Russia. I bet no West MSM covers anti-NATO protests in Ukraine (they report only about our far-right militants preparing to fight russians, as I can see).”

It looks like this is not the original source. All I can find in that regard is lots of tumblr posts (this seems to be the first one: https://fuckyeahmarxismleninism.tumblr.com/post/675720711979008000/happening-now-an-antiwar-rally-in-kiev-ukraine) referring to Dmitri Kovalevich.
