Prime Minister Mateusz Morawiecki, Speaker of the Sejm, lower house, Elzbieta Witek and head of the ruling party Law and Justice (PiS) Jaroslaw Kaczynski laid wreaths and flowers at monuments to Lech Kaczynski and to the victims of the disaster, located on Warsaw's Pilsudskiego Square.
The same delegation later laid wreaths at the graves of the Smolensk air crash victims at the Military Cemetery in Powazki in Warsaw.
Both ceremonies were attended by the Deputy Prime Minister, deputy head of President Lech Kaczynski's Office, Jacek Sasin, Deputy Prime Minister and Minister of Culture Piotr Glinski and Minister of National Defence Mariusz Blaszczak as well as a group of PiS MPs.
"Ten years since the Smolensk disaster. This was a moment when time stopped. That scream echoes loudly in our ears. We experienced a national tragedy as a community. Today, in other circumstances, we also need unity. We honour the memory of the victims of Katyn and the Smolensk tragedy," Morawiecki wrote in a Twitter post.
President Andrzej Duda, on Friday, laid flowers at the tomb of Poland's late First Couple, Lech and Maria Kaczynski, in the crypt of Krakow's historical Wawel Castle in southern Poland.
“All those who flew to Smolensk with President Lech Kaczynski on April 10, 2010, went there guided by their hearts because they were Polish patriots,” Duda said.
On April 10, 2010, a Polish government plane carrying then Polish President Lech Kaczynski, his wife and a large delegation of top state and military officials crashed during a landing attempt in heavy fog on an airfield in Smolensk, killing all on board.
The delegation was on its way to Katyn for commemorations of the Katyn Forest Massacre, in which Soviet security units mass-executed 22,000 Polish POWs, mainly army officers, policemen, prison wardens and administration staff. (PAP)
