Turin, 9 April (AKI) - Media outlets in the northern Italian city of Turin have been put on high alert after suspected anarchists sent a parcel bomb to the offices of a leading Italian newspaper, La Stampa, on Tuesday.

The device was live but failed to explode due to a defect in the primer, according to bomb disposal experts sent to defuse it.

No message was found inside the parcel but the type of bomb was typical of anarchist devices, according to anti-terrorism investigators.

Police in Turin have warned all newspapers and media organisations to be on their guard for suspect packages delivered to their offices.

A Greek-linked Italian anarchist group, the Informal Anarchist Federation (FAI) claimed responsibility for a package bomb found outside the Greek embassy in Rome and defused in December 2010.

Nobody was injured in the incident, but two parcel bombs at the Chilean and Swiss embassies in the Italian capital that same month seriously injured two people who opened them.

FAI's previously unknown 'Olga' cell claimed the kneecapping of nuclear company Ansaldo's chief Roberto Adinolfi in the northwestern port city of Genoa last May. FAI also threatened future attacks on state companies.
