Poland finds Russia at fault for presidential jet crash

A Polish report has found that Russia was partly to blame for the air crash last year which killed then-President Lech Kazynski.

It said that pilot error was the main reason for the crash, but that air controllers and poor lighting at Smolensk were also at fault.

The crash killed 96 people and has been a source of tension between the two countries.

Russia previously blamed the Polish crew for the April 2010 accident.

The report by Warsaw said airport lighting was "defective and incomplete", while a landing zone official had given "erroneous information" to the crew as they prepared to land at the Russian city of Smolensk.

All those on board, who included officials spanning the country's military and political elite, were killed when their airliner crashed while trying to land in heavy fog.

They had been on their way to a memorial for the victims of Katyn, where 20,000 Polish officers were massacred by Soviet forces in 1940
