Veiligheidsdiensten verwachten meer bombrieven uit Bologna (en)

The German security services said yesterday that more letter bombs are probably on their way to senior EU figures.

In an internal document reported by German daily Die Welt, the German security services say that a "series of pre-prepared letters" is to be feared. The German police added that "further letter bombs are already in the postal system or have recently been given to the postal service".

Especially high vigilance will have to be maintained at the beginning of next week when the European Parliament holds its session in Strasbourg, due to a backlog of unopened letters possibly containing bombs.

Anti-Constitution campaign

Further details have also emerged about the group suspected of carrying out the bombing campaign.

The anarchist group "Federazione Anarchica Informale" (FAI) is believed to be behind the bombing and is estimated by Italian officials to have about 350 members.

The group is said to be waging its campaign against EU "exploiters" and is passionately opposed to the establishment of a European Constitution, according to Die Welt.

The President of the European Commission, Romano Prodi - who received a letter bomb in late December - was targeted as "the representative of ... a repressive new European order".
