Q&A: Charles Taylor on trial

Troops loyal to Mr Taylor were renowned for their brutality

The war crimes trial of Liberia's former President Charles Taylor is drawing to a close.

The case, which is being held at a UN-backed court in The Hague, has its roots in the instability and conflicts that plagued Liberia and Sierra Leone in the 1990s.

Who is Charles Taylor?

Charles Taylor started Liberia's civil war as a warlord in 1989, before being elected president in 1997.

He governed for six years before heading into exile in Nigeria.

In August 2003, with rebels already in the capital, he agreed to a deal to go to Calabar in southern Nigeria to end the conflict.

What is he accused of?

He faces 11 charges of war crimes and crimes against humanity over his alleged role in the brutal civil war in neighbouring Sierra Leone, where he is accused of backing rebels responsible for widespread atrocities.

• Profile: Charles Taylor

Mr Taylor is accused of selling diamonds and buying weapons for Sierra Leone's Revolutionary United Front rebels, who were notorious for hacking off the hands and legs of civilians during their decade-long war.

Tens of thousands of people died in the interlinked conflicts in Sierra Leone and Liberia.

Instability also spread into neighbouring parts of Ivory Coast and Guinea.

Human rights activists have accused Mr Taylor of being at the centre of a West Africa-wide web of armed groups.

The United Nations-backed court in Sierra Leone sought his extradition to face justice in Freetown, where others alleged to have committed war crimes are already on trial.

The court's chief prosecutor once said Mr Taylor was the third most wanted war crimes suspect in the world.

How did the trial come about?

He was given asylum in Nigeria in order to end Liberia's civil war.

Human rights groups accused him of breaking the terms of that deal by continuing to meddle in Liberian politics.

Nigeria always said it would not extradite him to Sierra Leone, but would send him back to Liberia after the two-year transitional period if the new government there requested it.

Liberia's President Ellen Johnson-Sirleaf took office in January 2006 and made an extradition request shortly afterwards.

A few months later, Nigeria's then President Olusegun Obasanjo said that Liberia's new government was free to take Mr Taylor into custody.

Then he disappeared.

However, he was recaptured and Nigeria repatriated him to Liberia and a UN helicopter took him to Sierra Leone and into the custody of the tribunal.

His arrest was greeted as a sign that African warlords would no longer enjoy impunity.

Why is the trial being held in The Hague?

The trial is being held in The Hague, not by the International Criminal Court but by a United-Nations backed Special Court for Sierra Leone.

This special court had been created to hold all of its proceedings in Sierra Leone, to allow victims of these alleged crimes to see justice at work.

But, the case was moved to the Netherlands for fear of fresh instability in Sierra Leone and Liberia.

Before the transfer, a court in Freetown heard the 11 charges against him.

Why did supermodel Naomi Campbell appear at the trial?

Ms Campbell was subpoenaed to testify as it is alleged she received diamonds from Charles Taylor in September 1997, when both attended a star-studded charity dinner given in South Africa by the then South African President Nelson Mandela.

A fellow guest, US actress Mia Farrow, has also been called to testify along with Ms Campbell's former agent, Carole White, who said she heard Mr Taylor say he was going to give Ms Campbell some diamonds.

The allegation is part of the prosecution's case against Mr Taylor for his actions in the Sierra Leone civil war.

What happens next?

The key point in the trial will not be whether Mr Taylor committed the acts himself, but whether he ordered, supported or condoned such acts.

Mr Taylor has consistently denied all charges, which is why Ms Campbell comes into the story. The former Liberian leader has denied ever having rough diamonds in his possession.

If he is found guilty, Mr Taylor would serve his term in the United Kingdom as the Dutch government agreed to host his trial as long as any ensuing jail term was served in another country.
