(CNN) -- British supermodel Naomi Campbell has asked to postpone her testimony at the "blood diamonds" war crimes trial for the former Liberian president, the chief prosecutor's office said Thursday.
Campbell did not want to be involved in the trial but was subpoenaed on July 1 to appear at the tribunal for Charles Taylor, who faces war crimes charges over a brutal conflict in Sierra Leone that was fueled by rough diamonds, also known as blood diamonds or conflict diamonds.
Witnesses have said Taylor gave Campbell a diamond.
Campbell was scheduled to appear July 29 at the trial in The Hague, Netherlands. She has requested to postpone her testimony to August 5, the prosecutor's office said. The judge will make a decision on the request Monday.
Prosecutors had rested their case against Taylor in February 2009. They asked to reopen it specifically to call Campbell, as well as actress Mia Farrow and a witness named Carole Taylor, court papers show.
Prosecutors said they learned in June 2009 that Taylor had given the supermodel a diamond in South Africa in 1997. Farrow confirmed it, they said.
