During his visit to Ukraine, President of Poland Andrzej Duda visited the Polish military cemetery in Bykivnia (Kyiv), where he honored the memory of the victims of Katyn.

"Truth and memory must continue its path. Today, at the Polish military cemetery in Bykivnia, I am honoring the memory of 3,435 Polish prisoners tortured 80 years ago by the NKVD from the Ukrainian Katyn list, who died for a free and sovereign Poland," Duda wrote on his Twitter microblog.
