Special:Malaysian airliner crashes in Ukraine

KHARKIV -- A train bearing the dead from the downed Malaysian airliner finally reached Ukrainian government-held territory Tuesday, but the pro-Russian separatists in control of the crash site showed little willingness to allow the full-scale investigation demanded by world leaders.

Five days after the plane was blown out of the sky, refrigerated railcars bearing victims' bodies gathered up after several days in the sun rolled out of the war zone and into a weedy railyard in the city of Kharkiv.

The dead will be flown to the Netherlands, the homeland of most of the victims, for identification.

The Dutch government declared Wednesday a day of national mourning as the country prepared for the arrival of the first bodies in the afternoon.

It was unclear how many of the 282 corpses reported found so far were on the train. The crash killed all 298 people aboard Malaysia Airlines Flight 17.

Jan Tuinder, the Dutch official in charge of the international team dealing with the dead, said that at least 200 bodies were aboard the train and that more remains could be found once the body bags are examined fully.
