Italian Prime Minister Silvio Berlusconi has called on the US to show Italy the “fullest respect for its sovereignty” – something that Washington’s ambassador promised him it had and always would do.The meeting comes amid a political row over the alleged kidnapping of a terrorism suspect in Milan by the CIA. Last week an Italian judge issued arrest warrants for 13 people implicated in the affair which includes allegations of torture. Meanwhile justice authorities in Genoa say they have broken up an illegal group which had been formed to hunt down Islamic militants. “This group was highly structured with an internal hierarchy,” explained prosecutor Domenico Porcelli. “It tried to win the trust of government officials in the US, Israel and Nato.” Those leading the investigation say the group was founded in the wake of the train bombings in Madrid last year and included members of the Italian police force and prison guards. The group called itself the Department of Strategic Anti-Terrorism Studies and the suspected leaders are claimed to be members of a far-right group.
