An envelope which exploded at the European offices of the International Monetary Fund in Paris on Thursday bore a Greek return address.
Greece’s public order minister has said the suggestion was that it was sent by an opposition party official.
“The French authorities just informed us it was mailed from Greece,” Nikos Toskas told Ant1 Television.
Toskas said Thursday’s letter bomb, which injured an administrative worker when it exploded at the IMF in Paris, had been sent in the name of Vasilis Kikilias, a senior New Democracy official.
“It is not at all pleasant that these parcels originated from our country but the issue of terrorism affects all European countries,” Toskas said in his television interview.
Kikilias, a former public order minister, could not be contacted for comment.
Earlier in the day, a Greek militant group, the Conspiracy of Fire Cells, had claimed responsibility for a similar package containing explosives that was intercepted by the German authorities on Wednesday.
The package, addressed to German Finance Minister Wolfgang Schaeuble, had listed Adonis Georgiadis, the vice-chairman of Greece’s conservative New Democracy Party, as its sender.
The Conspiracy of Fire Cells has previously claimed responsibility for a wave of parcel bombs sent to foreign embassies in Athens in 2010.
