Attempted bombing of Jewish Community in Berlin solved

The Tagesspiegel reports that the attempted bombing of the Jewish Community Center in Berlin in the fall of 1969 is finally resolved. The story starts like that (translation by me):

The incident is largely forgotten – but did make history. On November 1969 around 250 people gathered in the Jewish Community Center in Berlin to commemorate the victims of the Pogrom Night standing unsuspecting beside a bomb. But nothing happened. A day later a cleaning lady heart a ticking noise in the soda machine.

Note: The Pogrom Night also known as the Kristallnacht, but this name is not used in Germany anymore since it is Nazi slang.

Now it became clear that the left-wing anti-Israel group Tupamaros West-Berlin was behind the assault. For them Israel represented the worldimperialism and the suppression of Palestinians.
