President marks 79th anniversary of Soviet invasion of Poland

President Andrzej Duda on Monday laid a wreath at Warsaw's Monument to the Fallen and Murdered in the East on the 79th anniversary of the Soviet aggression on Poland.

Exactly 79 years ago, on September 17, 1939, just days after Nazi Germany's invasion of Poland, the country was attacked by the Soviet Union.

The Red Army's attack on Poland came in line with the secret protocol included in the Soviet-German Treaty of August 23, 1939, referred to as the Ribbentrop-Molotov pact.
