A RADICAL ANARCHIST GROUP in Italy has claimed responsibility for a recent spate of parcel and letter bombs in Switzerland, Italy and Greece, in which three people were injured.

Yesterday, two workers at a nuclear power industry office in Olten, Switzerland, were injured by an explosion as they were opening the morning’s post. Swiss police said the two women suffered superficial injuries.

One person was injured in a blast in Italy and authorities at a maximum security prison in Greece defused a device which had been mailed there.

A proclamation from the Informal Anarchist Federation (FAI) was found inside the remains of the bomb in Olten.

According to Swiss authorities, the note calls for the release of three people imprisoned for the attempted bombing of an IBM research centre near Zurich last year.

In December, the FAI said it had organised the parcel bomb attacks on embassies in Italy in which two people were injured, and said it was responding to calls from a Greek anarchist group to increase its campaign.

Nine suspected members of that Greek anarchist groups are currently on trial for their alleged involvement in a bombing campaign in November 2010 which sent explosives to a number of embassies in Europe, as well as the offices of Angela Merkel and Silvio Berlusconi.
