Unofficial Anarchist Federation (FAI) took responsibility for the attacks against Swiss and Chilean embassies in Rome, in which two embassy workers were injured, Italian news agency ANSA reports.

An anarchists’ message, found in a box close to one of the injured embassy clerks, read “Long live FAI, long live anarchy”.

Antiterrorist Police Unit, which investigated the message, did not wish to comment the Italian agency’s allegations, AP reports.

Italian Minister of Interior Roberto Maroni said Thursday that the anarchists are most probably behind the explosion in Rome and that a number of elements in the investigation points to that.

The first bomb exploded on Thursday around noon in the Swiss Embassy, and the clerk who opened the box sustained injuries on his chest and arm, but his life is not endangered.

Three hours later, a package with a bomb went off in the Embassy of Chile, where one of the employees sustained heavy injuries on his head and chest, and he is at risk of losing an eye.

Police and the Italian officials connect these explosions with last month’s incidents in Greece, when the anarchists sent 14 bomb-packages to embassies in Athens, as well as to French President Nicola Sarkozy, German Chancellor Angela Merkel and Italian Prime Minister Silvio Berlusconi.

Two packages exploded, but nobody was injured. Responsibility for these attacks was taken by the group called “Fire cells conspiracy”.
