During the commemorative events in Warsaw, dedicated to the anniversary of the Volyn massacre, he stated the need for both sides to recognize the fact of these events.
Duda noted that this is a difficult topic for Ukrainians, "because it is very embarrassing."
At the same time, he stressed that "the truth must be heard."
“It must be made clear that we are not talking about revenge, about some kind of answer,” RIA Novosti quotes him.
Earlier, the director of the Russian Foreign Intelligence Service, Sergei Naryshkin, said that Poland's plans to restore control over Western Ukraine are dangerous for Europe.
