Eight parcels, suspected of being booby-trapped, were intercepted by police authorities in Athens on Monday, at a post office sorting centre in Northern Attica.

The packages were about to be dispatched to an array of multinational companies, individuals, and political authorities throughout the EU, not least among them Jeroen Dijsselbloem, President of the Eurogroup, according to some reports.

Counter-terrorism authorities have been on the lookout since last week, when two booby-trapped parcels were sent from Greece to the German Finance Ministry and to the International Monetary Fund offices in Paris.

The former, addressed to Wolfgang Schaeuble, was seized by German police, but the latter exploded, causing minor injuries to an administrative officer.

According to sources, the packages stated Greek politicians as senders; authorities suspect an urban guerrilla group, the Conspiracy of Fire Cells, which claimed responsibility for the first booby-trapped parcel, although this has not yet been established.
