The far left terror group Antifa appear to be behind it. So that's alright then.
""The brutal attack comes less than a week after an office belonging to the AfD in the city of Döbeln was bombed in what is also believed by the State Criminal Police Office (LKA) to have been a politically motivated attack.
The AfD say they keep track of attacks against their officers, members, and their homes, and gave statistics to Breitbart London which showed that attacks have risen from only four in 2014 to well over 600 in 2017.
Alt-left extremist Antifa violence has also become more violent and more pronounced in Germany over the last several years, with members of the extremist organisation releasing terror manuals encouraging attacks on the AfD.
A report released by the German domestic intelligence agency BfV last June confirmed the rise in far-left violence by showing the number of violent crimes to have increased 88 percent from 2012 to 2017.""
