An adviser to Ukraine's Interior Minister says a Malaysian passenger plane carrying 295 people has been shot down over a town in the east of the country.
Anton Gerashenko says on his Facebook page the plane was flying at an altitude of 33,000 feet when it was hit Thursday by a missile fired from a Buk launcher.
CBS News has not confirmed that the plane was shot down.
Malaysian Airlines tweeted: "Malaysia Airlines has lost contact of MH17 from Amsterdam. The last known position was over Ukrainian airspace."
A source told Interfax that the Boeing plane was flying from Amsterdam to Kuala Lumpur.
The NTSB, FAA and Boeing are all aware of the reports of the crashed Malaysian Airlines plane - they're still in the process of gathering information and don't have anything more to add at this time.
NTSB says that if this is a Boeing 777 plane, they would have stake in the investigation.
