Police in Italy have arrested six people in connection with recent killings attributed to leftist militants.

The six, arrested in pre-dawn raids, are being held over the killing of two government advisers working on labour reforms, said Italian Interior Minister Giuseppe Pisanu.
Mr Pisanu said the arrests had cut the main root of the Red Brigades group, which is believed to have been dormant for more than a decade until the killings of Massimo D'Antona and Marco Biagi in 1999 and 2002 respectively.
The Red Brigades claimed responsibility for the killings of both men and the same gun was used in both attacks.
Police officials said the six - four men and two women - were tracked down in an investigation which began with the arrest earlier this year of an alleged Red Brigades member after a shoot-out on a Rome-Florence train.
The suspect, Nadia Desdemona Lioce, has been in custody since she was captured in March.

The investigators said that information on her handheld computer had led them to make the latest arrests, which took place in Rome, Florence, Pisa and Sardinia.
The modern-day Red Brigades are seen as the heirs of the left-wing group of the same name which carried out attacks in Italy in the 1970s and early 1980s.
The attacks included the 1978 kidnapping and killing of former Italian Prime Minister Aldo Moro.
