THE PRIME MINISTER of Poland Donald Tusk has criticised a Russian investigation into a fatal plane crash last April that killed 96 Poles – including the country’s president.

Tusk said that the Russian report was “unacceptable” and added some of the conclusions were “without foundation”. Russia has been investigating the circumstances that surrounded the fatal crash, which occurred near the western Russian town of Smolensk.

Tusk would not go into detail about the findings of the report, but told reporters in Brussels:

From the Polish point of view, the draft report from the Russian side as it has been sent is without question unacceptable.

This negligence and mistakes or lack of positive reaction to what Poland has been asking for, all these things allow us to say that some of the report’s conclusions are without foundation.

Russian President Dmitry Medvedev visited Poland last week and reiterated a promise to cooperate over the crash investigation, the BBC reports.

Poland’s first couple, Lech Kaczynski and his wife Maria, were included in the fatalities in April; the group had been travelling to a memorial ceremony for the World War II Katyn massacre.
