Italian police have arrested five suspected militant anarchists they believe were part of a group that sent letter bombs to top European Union officials.
In an overnight raid, police near the central Italian town of Perugia seized the five they said were members of a group called "Coop/Fai", an acronym which stands for "Against all political order/Informal anarchic federation".
Police described Coop/Fai as a group dedicated to "terrorism and the subversion of democratic order".
Active since 2003, the group claimed responsibility for letter bombs sent to Prime Minister Romano Prodi, then president of the European Commission, as well as the president of the European Central Bank and other European Union institutions.
