The London bombings, the Paris riots and, more recently, the cartoon controversy - Europe's Muslims are scarcely ever out of the news.

In this three-part series, Roger Hardy goes in search of the roots of Muslim alienation, asks if Muslim anger is justified or unjustified - and tries to gauge where Europe and its Muslims are heading.

Part Three

The scene shifts to Milan, which has acquired a reputation as a "hub" of Islamic radicalism.

Muslims have arrived in Italy more recently than in northern Europe, and few have acquired Italian citizenship.

The programme looks at the social problems confronting a new and insecure immigrant community - and asks whether the failure of efforts at integration will increase the danger of radicalisation.
