Saif, Saadi and Mohammed Gadhafi, sons of Libyan leader Moammar Gadhafi, were captured Sunday by rebels who stormed Tripoli in their quest to overthrow the Gadhafi regime.
Saif Gadhafi, along with his father and Abdullah al-Senussi, Moammar Gadhafi's longtime intelligence chief and brother-in-law, are accused of crimes against humanity in the ICC arrest warrant.
Representatives from the court located in The Hague, Netherlands, and the rebel Transitional Nation Council were to meet Monday to discuss a possible transfer, al-Jazeera reported.
The whereabouts of Moammar Gadhafi, his other sons and Senussi were unknown. Published reports indicate a belief among rebel leaders they fled to southern Libya, Chad or Algeria.
Mohammed Gadhafi told al-Jazeera he surrendered, expressing sadness about the fighting in Libya.
"What's happening in Libya is very upsetting. The killing between brothers, between Muslims, is something that saddens me," he said.
Saif Gadhafi, in his last public appearance several weeks ago, said he was trying to negotiate an alliance with the Islamic faction among rebel forces to drive out the liberals, The New York Times said.
Moammar Gadhafi also had another son named Saif -- Saif al-Arab Gadhafi, who was killed in an airstrike in late April.
