Warsaw: Polish prosecutors said on Tuesday they
have questioned 60 witnesses as part of the ongoing
investigation into the plane crash in Russia that killed
President Lech Kaczynski and 95 others.
Polish and Russian prosecutors are holding separate
investigations into the April 10 crash in Smolensk, Russia but
are cooperating with one another.
Poland`s military prosecutors said in a statement that
all possible versions of the cause and circumstances of the
crash are being taken into consideration.
"None has been ruled out, prosecutors said.
Russian investigators have initially ruled out technical
problems and suggested a possibility of human error.
The Soviet-made Tupolev 154 crashed on the approach to
Smolensk airport. Kaczynski and others _ including top
civilian and military officials _ were to pay respect to some
22,000 Polish officers killed in 1940 by the Soviet secret
security in the Katyn forest and elsewhere.
Polish prosecutors said that they have analyzed video
footage of the debris taken right after the plane went down,
and another video that shows very bad weather conditions at
the site before the crash.
The prosecutors are still trying to establish the exact
timing of the crash from the four flight recorders that are
being analyzed in Moscow and Warsaw.
