British model Naomi Campbell appeared Thursday at the war crimes trial of former Liberian President Charles Taylor. She testified that she had received a pouch of uncut diamonds after meeting Taylor at a charity dinner in 1997 in South Africa. But, she said, she did not know if the gift came from Taylor. Prosecutors are trying to link Taylor to the so-called blood diamonds, which have been used to finance a civil war in Sierra Leone. Melissa Block talks to BBC reporter Peter Biles about what happened in the courtroom.
