London: British Prime Minister David Cameron on Sunday urged Libya's leaders to ensure Muammar Gaddafi's son Seif al-Islam was tried "in line with international standards" following news of his capture.
"The Libyan government has told us again on Sunday that he will receive a trial in line with international standards, and it is important that this happens," Cameron said in a statement.
"Britain will offer every assistance to the Libyan government and the International Criminal Court to bring him to face full accountability and justice for what he has done."
Gaddafi senior, who ruled Libya with an iron first for more than four decades, was killed on October 20 when forces of Libya's new regime captured his home town of Sirte.
Cameron said the Libyan government's announcement on Sunday of Seif al-Islam's arrest in the south of the country "shows we are near the end of the final chapter of the Gaddafi regime.
"It is a great achievement for the Libyan people and must now become a victory for international justice too."    

"He could have contributed to a more open and decent future for his country, but instead chose to lead a bloody and barbaric campaign against his own people.
"The fate of the Gaddafis should act as a warning to brutal dictators everywhere."
Seif al-Islam is wanted by the International Criminal Court on charges of crimes against humanity for crushing anti-regime protests.
The 39-year-old used to have strong links to Britain. He graduated from London School of Economics with masters in philosophy, policy and social value in 2003 and took a PhD in philosophy in 2008.
But these ties became an embarrassment for the LSE once the revolt began in Libya earlier this year and the institution cut its links with Seif.
Britain was at the forefront of international efforts to support Libya's rebels against Gaddafi, and was one of the first countries alongside France and the US to launch military action under a UN mandate in March.

Russia urges fair trial

Russia on Saturday hailed Libyan leaders' decision to send Saif al-Islam, the arrested son of former Libyan leader Muammar Gaddafi, to court and expressed hope that he would receive a fair trial.

"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.

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

He 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 on June 27 against him, his father and former intelligence Chief Abdullah al-Senussi on charges of crimes against humanity.

Russian envoy praised Libyan leaders for not handing al-Islam to the crowd that could lynch him in a matter of moment like it was with his father, who was captured and killed by rebels 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.

The European Union described the arrest of Gaddafi's son as "a very significant development" and called for Libyan leaders to cooperate with the ICC.

Saif's father Muammar Gaddafi was killed on October 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.
