Amanda Knox faces Italy retrial over Kercher murder

Italy's highest court has ordered US student Amanda Knox and her former boyfriend Raffaele Sollecito to face a retrial over the 2007 killing of Briton Meredith Kercher.

Miss Knox and Mr Sollecito spent four years in jail for murder but were freed on appeal in October 2011, largely on the grounds DNA evidence was flawed.

Alan Johnston report from Rome, where he says there could still be "years to go" in the case.
