Italian officials say police have arrested two Afghan men and a Pakistani as part of an investigation into a militant cell suspected of planning attacks in Italy, France, and Britain.
Prosecutor Roberto Rossi said on May 9 that there was no evidence that any attack was imminent "but it is clear they were making preparations."
The Afghan suspects are Hakim Nasiri, 23, and Gulistan Ahmadzai, 29.
Nasiri is accused of international terrorism and Ahmadzai of assisting illegal immigration.
Reports said a third man, 24-year-old Zulfiqar Amjad, a Pakistani also suspected of aiding illegal immigration, was later detained.
Warrants have been issued for two other Afghan suspects.
Video clips and photos on the detainees' mobile phones suggest they were planning attacks against landmarks in Bari, Rome, Paris, and London.
