A court in central Italy has been shown graphic video footage of the crime scene where a British student was killed, prompting the American accused in her slaying to bury her face in her hands.

Amanda Knox quickly looked away and held her head down when images of Meredith Kercher's body were shown in court Thursday. Knox and her former boyfriend Raffaele Sollecito are on trial in Perugia for the killing. Both deny wrongdoing.

Knox had been exchanging smiles and whispers with Sollecito from a distance, but she turned somber when a prosecution witness aired videos showing the blood-splattered room, Kercher's face and her foot sticking out from a duvet.

Kercher's body was found Nov. 2, 2007 in the apartment she shared with Knox.
