The body of Polish President Lech Kaczynski...
The Soviet-made TU-154 carrying Kaczynski hit the top of trees as it attempted in thick fog to land at a Smolensk airport in west Russia on Saturday morning, killing all the 97 people on board the plane.
The plane was taking Kaczynski and a delegation of top Polish officials to a ceremony to pay tribute to some 20,000 Polish officers who were executed in Katyn and other locations by Soviet secret police in 1940.
"Currently investigative measures are under way. After they are over, a ceremony will be held to pay last respects to the Polish president whose body will be delivered from the Smolensk mortuary to the aerodrome, after which it will be delivered to Warsaw," Andrei Yevseyenkov said.
Jaroslaw Kaczynski, the twin brother of the late Polish president, earlier on Sunday identified the body of Lech Kaczynski.
The bodies of the other Polish plane crash victims have been delivered to Moscow for identification. Twelve of them have already been identified.
