Amazing.
Yesterday, the entire city was in chaos because there was a cable fire in the most important transport hub. Apparently, the entire eastern half of Berlin and its suburbs were cut off, and the impact was felt in the entire city. It was basically a collapse of public transit. Yet again a complete failure of the S-Bahn train service (yet again, because that thing is so run-down it has been in total chaos for two years now).
Turns out that it was a case of arson, and a leftist group calling itself "The grudge of Eyjafjallajökull" was responsible. They posted a note containing a totally confused reasoning about arms proliferation and nuclear power and waste transport.
While nobody has been hurt as a direct consequence of this act (apparently, there have been several car crashes on the motorways in and around the town due do increased traffic), is this anything other than terrorism?
