On the same day as the assassination of the Russian ambassador in Turkey, and the truck attack in a Christmas marken in Berlin, there was a shooting in a mosque in Zurich that left three wounded.
And this attack appears to be shaping up to be of the crazy persuasion. According to Swiss media (here is a link in English):
-The attacker was a 24-year old Swiss man and apparently was known to the police.
-He was already being sought in connection with the stabbing death of a man whose body was discovered in a park on Sunday morning.
-He “may have had links to the occult”, whatever that means.
-The police says that after shooting the mosque he killed himself.
This one smells of madness to me.
