Horrible 60-character-limit caused that title. Sorry.
Russian-backed Ukrainian separatists (most likely) just shot down a plane and killed 295 civilians.
It has been (unofficially) confirmed:
Russian separatist leader of the Donetsk People's Republic, Igor "Strelkov" Girkin, posted this to Facebook shortly after Malaysian Airlines flight MH17 Amsterdam to Kuala Lumpur was recognized as having crashed over Ukraine:
To my understanding, it translates to:
Just shot down an AN-26 plane on Toreza area, crashed around the the Progress mine.
We warned them about flying in our sky.
And here's a video confirming another [plane] falling.
The [plane] fell past the territory, living sector was not hit.
Civilians were not hurt.
And there's also information about a second plane being shot down, looks to be a SU.
The wreckage of that same plane crash has the remnants of the exact Malaysian flight, as well as other evidence, such as the ticket.
