Prime Minister Donald Tusk on the tragedy in Warsaw's Praga Północ district

"In human terms, I will tell you that it is not his intervening colleague who is liable for the death of a policeman, but a thug with a machete," Donald Tusk wrote on social media, referring to the tragic intervention of the services in Warsaw. The Prime Minister besides stipulated that "he is not a judge" and he will not "pass judgment".
