WARSAW, Poland (AP) — A divisive movie supporting a theory that the 2010 plane crash that killed Polish President Lech Kaczynski and 95 others was an assassination orchestrated by Russia will premiere in Warsaw.

The crash in Russia was among Poland's greatest tragedies since World War II and sparked speculations as to its causes.

Polish and Russian experts blamed bad landing conditions at Smolensk airport and pilot errors. But Kaczynski's party insists that it was an assassination inspired by the Kremlin as punishment for his support for Georgia during its armed conflict with Russia. Moscow vehemently denies the allegations.

In the "Smolensk" movie's official trailer, the plane explodes in a ball of fire and circumstances suggest conspiracy.

President Andrzej Duda, who hails from Kaczynski's party, is expected to attend Monday's premiere.
