Fires and rioting in Stockholm suburb - The Local
Hopefully they will be quelled quickly before they could spread to other parts of Stockholm and cause inconvinience to visitors and tourists as well as embarassment for the Swedish government.
Oh dear -- a bit worrying, isn't it? Let's hope that no one gets hurt and that matters are resolved before long....and certainly well before the wedding day.
