A report by the Interstate Aviation Committee (MAK) on the Polish presidential plane crash in western Russia is "one-sided," Polish President Bronislaw Komorowski said on Wednesday.
"The MAK report on the Smolensk tragedy deserves to be criticized," Komorowski also said, describing the report as "lacking answers" to key questions.
Speaking at a parliamentary session later on Wednesday, Polish Prime Minister Donald Tusk was also critical about the Russian report.
"Polish documents demonstrate a more detailed record of the Smolensk disaster. However, it's a pity we failed to make a joint report with Russia," the premier said.
In his speech, Tusk also warned against anti-Russian rhetoric and attempts to politicize the tragedy.
"Finding out the truth about the tragedy should not turn into political gambling," he said. "Today we have the following two objectives: finding out the truth and preserving political accord in international relations."
He also criticized opposition members, who said that the plane crash was "murder" or a "terrorist attack."
"Not everyone [in Poland] was interested in learning the whole truth about the crash," he said. "The government tried to dig out all the truth, but it seems some people just don't want it."
Opposition leader Jaroslaw Kaczynksi, the twin brother of the deceased Polish president, left the parliamentary session hall after Tusk's speech.
Poland's envoy to MAK, who also made a speech to parliament, said Poland would report to the European Union "about problems in cooperation with Russia as far as the Smolensk disaster is concerned."
Then Polish president Lech Kaczynski and many Polish officials were killed when a Tu-154 plane crashed upon landing near the western Russian city of Smolensk on April 10, 2010.
The CIS International Aviation Committee (MAK) released a report on January 12 citing pilot error as the main cause of the tragedy, which occurred when the plane hit trees while attempting to land in thick fog.
Polish experts and officials have also criticized the report, saying it lacks sufficient evidence for its findings.
