The guy who detonated himself im Ansbach made a video prior to it, declaring his support for IS, and saying he will kill Germans in the name of God for what they did to muslims.
Authorities still say that they're not sure if he really was an IS supporter. They say he was a psychiatric patient, with battle scars from Syria, who had been treated for cutting his wrists twice. The prosecutor says he suffered from periods of depression.
Earlier, the perpetrator had gone to the police with another man, to file charges against a third man, accusing him of being a Hezbollah fighter.
In his backpack, police found enough material to make another bomb. Police doubt he intended to blow himself up with the bomb, they think he might have accidentally detonated, and had instead wished to place bombs at the festival that denied him access for not having a ticket. In his pocket they also found a bundle of 50 euro bills.
Looks like someone paid him well.
EDIT: Meanwhile in the Netherlands, last night, two more Turkish companies where torched by unknown pyromaniacs.
In Apeldoorn, an NGO of Turkish highly educated parents, which is a think tank for deradicalization efforts with links to Gulen was set on fire.
In Deventer, a Turkish religious society was set on fire. Quick action by neighbors prevented serious damage.
In my own neighborhood, there's glass everywhere now from Turkish cars having their windows smashed. Also, The Turks in my block (which are over 50% of my neighborhood's population) are sitting in their front yards, demonstratively wearing Turkish flag T-shirts. Those Turks who don't wear will likely have their car windows smashed.
