Eight of the suspects are of Tunisian origin and two are Italian. Among them is an Imam from the city of Teramo in the central region of Abruzzo.
The suspects are alleged to have “created many false accounts, through various companies to set aside large sums of money,” the prosecutor’s office in Aquila said.
The money was used to finance activities related to al-Nusra Front, the former Syrian branch of al-Qaeda, it said.
Part of the money was also intended for imams in Italy, “including one convicted for association with a group linked to international terrorism”.
An Italian accountant is also among the 10 suspects, whose property, money and real estate, said to be worth more than one million euros (over $1.1 million), were seized, the statement said.
