A court in Italy has reinstated the guilty verdicts against Amanda Knox and Raffaele Sollecito for the murder of UK student Meredith Kercher in 2007.
American Knox and her Italian ex-boyfriend Sollecito - who had pleaded not guilty - now face long jail sentences.
The latest verdict overturns the pair's successful 2011 appeal, which freed them after four years in jail.
Ms Kercher was stabbed to death in the flat she shared in Perugia with Knox.
Thursday's fresh appeal hearing in Florence was ordered by Italy's highest court, the supreme court in Rome.
