Pig heads have been left on the entrance to a migrant camp in the Netherlands, in an effort by some to give the Muslim refugees a hellish nightmare welcome to one of Europe's most tolerant nations. Unidentified perpetrators left some 14 pig heads at the entrance of a refugee center in Eschmarkerveld, near the city of Enschede, on early Wednesday morning. Nine pigs' heads were found on the fence, the rest laid out on the ground. Plastic bags full of blood in which the heads have been transported were also found at the site.
