UPDATE: Malaysia Airline Victims Returned To Netherlands

People in the Netherlands, where Malaysia Airlines Flight 17 originated, are observing an official day of mourning Wednesday as some of the remains of the victims arrive in the country.

Once they arrive, experts will start identifying those who lost their lives when the Boeing 777 was shot down over eastern Ukraine, last week.

But some of the remains, of as many as 100 of the 298 victims, were not among them.

Investigators think the rest are still at the crash site, and that some of the wreckage was moved and tampered with. 

Michael Bociurkiw, spokesman for OSCE Special Monitoring Mission to Ukraine said, “We did observe changes in the site, especially the burnt area where the wings and the fuel tanks went down. Fuselage has been moved.” 

Senior U.S. intelligence officials say they believe Russian-backed separatists hit the passenger plane with a surface-to-air missile.

They admit they have no evidence Russia was directly involved, but say Moscow created conditions that led to the plane being brought down.
