Police in Italy and France on Wednesday arrested eight Algerians and two Italians as part of an anti-terror operation, police in the southern Italian city of Naples said.

Those arrested in Italy were picked up in Naples and the nearby city of Caserta, and in Milan, police said. No details were provided on the arrests made in France, although the ANSA news agency said they were made in Marseille.

The suspects were believed to have links to the Salafist Group for Call and Combat, or GSPC, an Algerian group said to have links to Al Qaeda.

Police in Naples declined to give details pending a news conference in the city later in the day.

ANSA said the arrests were the result of a year-long investigation conducted by the police forces of the two countries.
