Italian police on Thursday arrested five Tunisians as part of what they said was a major operation against suspected supporters of Islamist terrorism in central and southern Italy.
The swoop is the latest in a series of similar raids this month, coming as Italy steps up the number of foreigners it expels.
On Wednesday, anti-terrorism police arrested an Italian citizen of Moroccan origin, who they said was an Islamic State sympathiser planning a truck attack.
“A vast anti-terrorism operation’’ was being carried out by special investigation forces based in Rome and the nearby town of Latina, police said in a statement on Thursday.
The five Tunisians detained are suspected of being part of a network connected to Anis Amri, the Tunisian, who killed 12 people when he drove a truck into a Christmas market in Berlin in December 2016, judicial sources said.
Amri was shot dead by Italian police near Milan four days after the Berlin attack.
Prosecutors suspect the arrested Tunisians of crimes including planning international terrorism, falsifying documents and helping illegal immigration of radicalised Tunisians, the sources said.
However, the sources said there was no evidence the suspects participated directly in the Berlin truck attack or that they were preparing any imminent attack in Italy.
As part of their operation, police were carrying out searches in Rome, the southern port city of Naples and the central and southern towns of Latina, Viterbo, Caserta and Matera, the sources said.
Interior Minister, Marco Minniti, said on Wednesday the security threat to Italy from Islamic State supporters was higher than ever because more foreign fighters were attempting to return to Europe via Italy after the jihadist group suffered defeats in Syria and Iraq.
So, far this year, 29 foreigners have been expelled from Italy as suspected threats to national security.
