Yeah. I was closely following the news, and the separatists bragged about shooting down another Ukrainian plane (they downed few helicopters and planes earlier).

Of course as soon as they knew it was foreign civilian plane they started to deny it.

This might be of interest, this the intercept of several phone calls by Ukrainian intelligence service (SBU) where separatists discuss the indecent.

If you trust SBU (and know russian) then that's reasonable proof, but if you trust only tweeter and https, it helps a lot when the rebel's commander admits freely on tweeter they were behind some incident.
