Tripoli (Libya), Nov 20 (IANS): Libyan interim Prime Minister Abdel Rahim el-Keeb has confirmed the capture of former Libyan leader Muammar Gaddafi's son Saif al-Islam and assured a fair trial for him, Xinhua reported Sunday.

Saif al-Islam was arrested Saturday in southern Libya and then brought by plane to the northwestern town of Zintan, where the angry crowd attempted to storm the aircraft.

"We assure Libyans and the world that Saif al-Islam will receive a fair trial," he said during a televised news conference held in the western Libyan town of Zintan, where Saif al-Islam is being kept in custody.

Russia Saturday expressed hope that Saif al-Islam would receive a fair trial, RIA Novosti reported.

"The international community today keeps close watch on Libyan authorities' ability to defend the results of war victory since the compliance with the generally accepted rules of treating captives is the key factor of this ability," Russia's presidential envoy to Africa Mikhail Margelov said.

Gaddafi's son has been on the run since the National Transitional Council's forces took over Tripoli in late August.

The International Criminal Court (ICC) had issued warrants June 27 against him, his father and former intelligence chief Abdullah al-Senussi on charges of crimes against humanity.

Russian envoy also praised Libyan leaders for not handing al-Islam to the crowd that could lynch him just like it happened with his father near his home town of Sirte late October.

The ICC said that Libya should surrender Saif al-Islam. However, the ICC did not rule out that Gaddafi's son would be tried in Libya rather than in The Hague.

Libyan interim government however wants a trial for Saif al-Islam only on Libyan territory.

Saif's father Muammar Gaddafi was killed Oct 20 soon after his capture by rebel forces during the final battle for his hometown Sirte.

Gaddafi ruled Libya for over four decades till he was overthrown in a popular revolution that started in February.
