We didn’t hear a whole lot about this, and I’m still not sure I understand everything going on, but these pictures help describe a bit.  It’s weird to see a place on fire that I was visiting about a year ago.  You can tell by the pictures, the Greek youth are protesting/rioting against police who murdered a 15 year old.  Of course I’m sure the actions are also tied into the center-right government.

I believe these incidents are more controlled now, and I wouldn’t let it change travel plans to the area.  But that’s just my take.
