A dead pig and four pig heads have been found buried on the site of a future mosque in an anonymous anti-Islam attack, police say.
The attackers sent anonymous letters to the media in the region near the mosque site in the town of Grenchen in canton Solothurn.
In the letter they said they had also poured 120 litres of pig’s blood on the ground, saying it was a test of Muslim faith whether the mosque would be built on the land afterwards.
