Ah, political propaganda from the rebels.
The problem with videos like this is that they provide no context. It doesn't tell you a damn thing about what's going on. It's a video of a pretty girl shot with a DSLR with a shallow depth of field. Is this even shot in the Ukraine? No idea. Could be a studio pretty much anywhere.
I don't know what's going on in Kiev. This wiki article is all I could find that is well cited: http://en.wikipedia.org/wiki/Rise_up,_Ukraine!
