UNITED NATIONS - The UN Security Council on Friday called on Libya to release four detained International Criminal Court staff members who are accused of smuggling documents to Muammar Gaddafi's son in custody.

The ICC personnel were detained last week while visiting Saif al-Islam Gaddafi in Zintan after it was alleged they gave him documents from supporters.

The ICC staff members were identified as Australian lawyer Melinda Taylor, Lebanese-born interpreter Helene Assaf, Esteban Peralta Losilla of Spain, the chief of the Counsel Support Section at the ICC, and Alexander Khodakov of Russian, external relations and cooperation senior adviser at the registry of the ICC.

Human rights groups, the court in The Hague, and the Australian government all have demanded they be released immediately but Libyan prosecutors say Taylor and Assaf will be held for at least 45 days while they are investigated.
