Find someone who speaks whatever language that is to translate for you. It’s definitely gun shots, I think.
As to my knowledge of Russian - the voices in the background shout “Idi otsyuda!”, which means - “Go away”.
And the guy who’s filming is saying “Ni huya syebe” which is a vulgar expression, something like “Fu***g hell”, or something like that.
The voice in Russian says what basically can be translated as WTF.
Russian gunshots sound different that Polish gunshots?
