The Hague, Nov 10 (IANS): The arrest of slain Libyan leader Muammar Gaddafi's son Saif Al-Islam Gaddafi is only a matter of time, International Criminal Court (ICC) chief prosecutor Luis Moreno-Ocampo has said.

"Muammar Gaddafi died, but Saif Al-Islam Gaddafi and Abdullah al-Senussi (former intelligence chief) are still indicted," Moreno-Ocampo told Xinhua.

"We are preparing their trials and we are trying to get them arrested," he said on the sidelines of a seminar on international justice, peace and crisis management held Wednesday at the Peace Palace in The Hague.

He said the ICC has begun investigations into not only reported atrocities by forces under the Gaddafi regime, but also allegations of crimes committed by NATO troops and forces led by the rebel Natiobnal Transitional Council.

"We are conducting new investigations on rapes," the ICC prosecutor said.

"We are connected with the new Libyan government which is preparing a strategy to deal with all these crimes," he said.

Though the whereabouts of Saif Al-Islam and al-Senussi remain unknown, the ICC received questions from Saif through intermediates regarding his legal rights if he was to come to The Hague, said Moreno-Ocampo.
