The institutions in Brussels, Strasbourg, Luxembourg and Frankfurt are reinforcing their security systems. After the letter-bombs delivered in recent days to the President of the European Commission Romano Prodi, to the President of the European Central Bank Jean Claude Trichet, to the headquarters of Europol and Eurojust in The Hague, and to MEPs Hans Gert Poettering, Gary Titley and Josè Ignacio Salafranca, controls are being stepped up. The police forces of the member countries and the political authorities of the EU agree that an anti-European campaign has been launched, probably aimed at curbing or discouraging the process of integration. President of the EP, Pat Cox, has expressed “deep concern” about the recent attacks, and urged MEPs to “be on the alert in their respective homes and offices”. He also promised “a reinforcement of security measures”. Still fresh in the minds of EU representatives is the memory of Swedish foreign minister Anna Lindh, a convinced supporter of her country’s entry into the euro area, who was assassinated in September; further light on her murder has been emerging in Stockholm in recent days.
