That's probably butthurt wanna be ASALA member young Armenian attacked bunch of Turks in Berlin. Berlin's population made up at least 1/4 Turkish Germans. ASALA is a terror organization same as Isis bombing airport's in 80's killing diplomat's or anything related to Turkey.

The thing is the guy do some attacks but western media claiming to be crash covering ethnicity of him. Imagine a Turk made this or even crashed into bunch of group. There will be huge propaganda to black Turkish people. Calling gray wolf attack etc..
Thanks to joint operations with MOSSAD and MİT ??

ASALA gone into Ashe's. Most of leftovers joined PKK. Both founded in Lebanon both trained by Palestinian militia and Syrian Intelligence service Al-Muhaberat in bekaa valley. That's tragicomically how conservative dumb Turks still supporting Palestinia..
Turkish proverb;
You reap what you sow.
After turning blind eye to those terror organizations cuz of Turkey hate. Today a German is killed. Tomorrow who knows a Swede from overdosis by PKK drug trade.
What is ASALA shortly.
