Four Algerians were arrested Friday on terrorism charges in northern Italy, a police official said.

The suspects were affiliated with the Salafist Group for Call and Combat, an Algerian group said to have links to Al Qaeda, said an official with the Carabinieri paramilitary police in the northern city of Padua. He asked that his name not be used because he was not allowed to talk to the media.

The four were allegedly in charge of financing and recruiting new militants as well as acquiring false documents, including identity documents and work permits for immigrants, the official said.

He said the group had its base in the nearby city of Vicenza but operated across northern and southern Italy.
