Muslims should report suspected members of the Islamic State terrorist group to police, as Italians did with leftwing terrorists in the 1970s and 1980s, Florence's imam said on Friday.
"The Muslim community also contains terrorists," Izzedin Elzir told Italian daily Corriere della Sera in an interview.
"We must report them in the way you did with the Red Brigades," said Elzir, who heads Italy's largest Muslim organisation UCOII.
"It is a moral imperative," added Elzir, who is also involved in an Italian project to combat the radicalisation of Muslim prisoners.
