There have been appeals eminating from Italy to put a stop to mafia-linked violence in the wake of the killing of six men in Germany. The victims, all Italian, were shot as they sat in cars outside a pizzeria in Duisberg. They were linked to the ‘Ndrangheta, a crime ring in the Italian region of Calabria. Italy’s Prime Minister Romano Prodi made a direct appeal to the young generations of southern Italy to help the government stamp out organised crime. German investigators say the murders are “very probably” the latest episode in a clan feud that started 16 years ago in the Italian town of San Luca. A local priest called for the women of San Luca to use their influence to calm the violence.
