(CNN) -- Libya's government on Tuesday appealed a request from the International Criminal Court to hand over Saif al-Islam Gadhafi, saying it should be given more time to make its own case. Gadhafi, son of deposed strongman Moammar Gadhafi, was facing an arrest warrant from the ICC for alleged crimes against humanity at the time of his capture, and the court is still seeking to prosecute him. Officials with the ICC, based at The Hague in the Netherlands, said Thursday that Libya must make arrangements to hand him over immediately. He has been held in the Libyan city of Zintan since his capture in November.
