AMSTERDAM (CNN) - The International Criminal Court is in negotiations with one of Moammar Gadhafi's sons, who is considering surrendering himself for trial.
"There are informal conversations, but they explore the possibility to appear before the court," said Luis Moreno-Ocampo, the court's chief prosecutor.
Moreno-Ocampo said a warrant is out for Saif al-Islam Gadhafi's arrest.
"And if he considers he is innocent, he has all the right to present his argument for the judges," he said.
The prosecutor said the court has evidence that shows Saif Gadhafi committed crimes against humanity in Libya.
"In according with our evidence, Saif (Gadhafi) was critically important in organizing the killings of civilians in Libya," he said. "And that's why we are prosecuting him."
The court does not know the current location of Saif Gadhafi.
His father, former Libyan leader Moammar Gadhafi, was fatally shot in the head earlier this month.
