Russia has transferred to Poland all materials concerning the investigation of the Polish presidential plane crash near Smolensk in April of this year.
"There is nothing more to transfer. We have transferred everything there was to transfer," First Deputy Prime Minister Sergei Ivanov said.
Verbatim reports of the communications between the plane crew and the air traffic controllers were handed over to Poland and published earlier. "It's easy to understand everything," Ivanov said.
