The chief prosecutor of the International Criminal Court has said that Saif al-Islam Gaddafi could face trial in Libya as long as the trial complied with the standards of the ICC.

Jose Luis Moreno Ocampo said to reporters in Tripoli:

"Saif is captured, so we are here to ensure co-operation,

"In May, we requested an arrest warrant because Libyans could not do justice in Libya. Now, as Libyans have decided to do justice, they could do justice and we'll help them to do it – that is the system.

"Our international criminal court acts when the national system cannot act. They [the Libyans] have decided to do it, and that is why we are here – to learn and to understand what they are doing and to co-operate.

"The law says the primacy is for the national system. If they prosecute the case here, we will discuss with them how to inform the judges and they can do it. But our judges have to be involved,"

A trial in Libya means Saif could face the death penalty. The most severe penalty that could be imposed by the ICC is a life sentence.

Amnesty International has called for the transfer of Saif gaddafi to the ICC.

Hassiba Hadj Sahraoui, Amnesty International's Middle East and North Africa Deputy Director said in a statement:

"After what happened after the capture of Mu’ammar and Mu’tassim al-Gaddafi, we hold the NTC responsible for preventing similar harm coming to Saif al-Islam al-Gaddafi, so that he can face justice for his alleged crimes in a fair trial with no death penalty."

"Investigating Saif al-Islam before the ICC offers an opportunity to ensure justice, truth and reparation for the victims of the crimes against humanity he is charged with committing against the Libyan people - justice that may have been denied with the apparently unlawful killing of Mu'ammar al-Gaddafi."
