The main events dedicated to the tribute to those who perished in Katyn will take place at Pilsudsky square in Warsaw. All names of the victims will be read aloud.
On April 13, the President is in Kharkiv, because there's Katyn cemetery, too. He will be in Kharkiv, as crimes were committed in several - at least four - place", Glinski said.
The information about Duda's visit to Kharkiv has not yet been confirmed by his representative Blazej Spychalski. He admitted that the details of the president's tour on the occasion of the 80th anniversary of Katyn massacre will be made public on the press conference next week.
Earlier, Duda claimed Russia clearly and consistently violated the rules of international law.
"Therefore, we cannot say that it is a reliable state that peacefully realizes its interests. We are an absolute supporter of observance of international law, while it is clearly and consistently being violated by Russia. We have repeatedly protested against this, defending Ukraine or Georgia. Of course, Moscow does not like it," he said.
