The UN Security Council on Monday demanded the release of the detainees [JURIST report]. The Presidents of the International Criminal Tribunals for Rwanda and the former Yugoslavia last week joined the ICC in calling for the immediate release [JURIST report] of the four staff members. Last week, Carr reported that three officials from the ICC and the Australian ambassador to Libya were able to visit [JURIST report] and assess the condition of the four ICC staff members. A spokesperson for the ICC said earlier that day that the Libyan government had failed to explain [JURIST report] why the four ICC staff members were detained and that their continued detention is a violation of international law. Earlier this month, a pre-trial chamber of the ICC granted a request by the Libyan government to postpone an order to transfer Saif al-Islam to ICC custody, after the Libyan government formally challenged [JURIST reports] the right of the ICC to try Saif al-Islam last month. In April, ICC chief prosecutor Luis Moreno-Ocampo asked the ICC to report Libya to the UN Security Council [JURIST report] for failing to turn over Saif al-Islam. Libya expressly denied [JURIST report] the ICC's request for such action and stated that Saif al-Islam will face trial within the country.
