An urban guerrilla group called Zero Tolerance on Monday claimed responsibility yesterday for setting off a rudimentary incendiary device outside the political office of New Democracy MP Fevronia Patrianakou.
The explosion occurred in central Athens on the night of July 4.
Nobody was injured in the blast.
The group posted a proclamation on the Indymedia website.
The same group has claimed similar attacks on the offices of ex-Prime Minister Costas Simitis and ex-government officials Vasso Papandreou, Mariliza Xenoyiannakopoulou, Christos Protopappas and Miltiadis Papaioannou, who all served with PASOK.
