An unknown group calling itself Forces of the Revolutionary Arc on Tuesday claimed responsibility for an explosion outside a tax office in Kifissia, north of Athens, on September 26, which caused damage but no injuries.

In a statement posted on the Internet, the group said the attack was “a first reaction to the state’s attempt to present itself as mediator and punisher of its Golden Dawn-supporting servants in a bid to throw up a smoke screen and conceal its own fascist form of governance and its new murderous measures.”

The statement added that the murder of the leftist hip-hop artist Pavlos Fyssas by a Golden Dawn supporter last month had been exploited by the government and that the “role of Golden Dawn was and remains to do the system’s dirty work.”
