Fighting in South Ossetia

If you haven't been following the news very closely the past few days you've likely missed this:
Following Georgia's attempt to retake the capital of breakaway territory South Ossetia. Citing the fact that many residents of South Ossetia are also Russian citizens, Russia has responded in kind with military strikes against Georgia.

I don't have an especially good handle on the situation myself, so I'm not going to try to describe it any further.

(Pertaining to comments in the shoutbox: I know this isn't a current events blog, but I feel this is important enough and has so far not been much mentioned in the mainstream media that it was appropriate.)

Edit [Isaac]: Some Russian forces have now moved beyond the disputed regions and entered central Georgia. There are also Russian troop buildups in South Ossetia and Gorgian troop buildups beyond the border.
