I can confirm that I can't reach any of those articles from Sweden, where I live. But these news are in no way being suppressed, most in Sweden knows of the social worker who was killed. And media frequently discuss the conditions in these migrant centers. It also appears that not all articles are blocked, I can for example reach
http://www.dailymail.co.uk/news/article-3416343/Sweden-asylu... from Sweden.
Still, this is both strange and unsettling.
