So sad

I've got the soccer on in the background and I'm watching the scenes in Warsaw just ahead of the kick-off of the Poland/Russia match with supporters of the teams attacking each other, riot police, water cannons, the lot.

This isn't football, but historic ill-feeling between the two nations surfacing, but it's awful to see it expressed this way and so sad for the true fans and the teams who just want to play and do well for their countries.
