Their deaths were the result of “an act of illegal intervention by the Russian side,” commission chief Antoni Masierevich told a news conference. “The main and indisputable proof of the intervention was an explosion in the left wing, which was followed by an explosion in the center of the plane,” said Macierewicz, who in 2015-2018 served as defense minister in Poland’s right-wing government. He denied any wrongdoing by the Polish pilots or crew, despite the bad weather at the time of the crash. The report echoes a number of previous allegations by the commission, which was appointed by a government led by Jaroslaw Kaczynski, the leader of the ruling Law and Justice Party, the late president’s twin.

Poland backs Ukraine in its fight against Russia and calls for tougher sanctions on Moscow for its invasion of Ukraine on February 24.

The suspicions are further fueled by Russia’s refusal to return the wreckage, which has complicated Poland’s investigation. Earlier, two separate reports by Polish and Russian aviation experts said the crash on the approaching dense fog at Smolensk airport, which lacked advanced aviation equipment, was the result of human error in adverse weather conditions. They found no evidence of a foul.
