ABIDJAN - Ivory Coast's former strongman, who nearly dragged his country into civil war in a bid to retain power, is being extradited to the International Criminal Court following the issue of a warrant for his arrest, his spokesman said Tuesday.

The ex-president has been under house arrest in the tiny village of Korhogo over 500 kilometres north of Abidjan since being ousted by internationally backed forces seven months ago.

In Abidjan, Gbagbo's spokesman Kone Katinan confirmed that the former ruler had left the remote village on a special flight headed to The Hague. "He's in the plane," Katinan said. The public prosecutor's office in Ivory Coast said Gbagbo changed planes in Bouake, the regional capital, before continuing to the Netherlands.

"I can confirm that he left Korhogo at 6:31 p.m. GMT. He is passing through Bouake, because the landing strip in Korhogo can only accommodate a small plane."

Gbagbo's Paris-based lawyer Emmanuel Altit said he had filed an appeal to stop the international arrest warrant issued Tuesday through Ivory Coast state prosecutors, but acknowledged that if it's not granted, the ex-president would be transferred overnight.

The development, which comes almost exactly a year to the day after Ivory Coast's disputed presidential election, was applauded by victims of Gbagbo's regime and by rights groups because of the signal it sends against impunity.

Once he arrives in The Hague, Gbagbo will become the first former head of state to be taken into custody by the tribunal since its founding in 2002. Sudanese President Omar al-Bashir has been indicted, though he refuses to surrender, while former Liberian warlord Charles Taylor and Yugoslav leader Slobodan Milosevic have been tried there by special ad hoc tribunals, rather than the international court.

The move could further stoke tension in Ivory Coast, however, because it gives the appearance of victor's justice, since grave abuses were also committed by forces loyal to the country's democratically elected leader, Alassane Ouattara, who enlisted the help of a former rebel group in order to force Gbagbo from office.

In the Abidjan neighbourhoods that voted in large numbers for Gbagbo, the frustration was palpable. Retired insurance salesman Jack Koutouan, 67, called the move "an abuse of the law."

Leaders of Gbagbo's party, whose members are either under house arrest or else in exile, called the pending extradition an "injustice."

"It's an injustice to judge him alone without judging (Guillaume) Soro," said party spokesman Augustin Guehoun, naming the country's defence minister who headed the armed group that invaded the country in order to install Ouattara.

The United Nations, Human Rights Watch and Amnesty International have documented how the advancing army set fire to villages that voted for Gbagbo, and executed those that could not run away, including the elderly and the disabled, by rolling them inside mattresses and then setting them on fire.

"He is not the only one responsible (for the human rights abuses committed during the post election period)," said 30-year-old Kossonou Agingra. "There were partisans of Alassane (Ouattara) who killed -- and partisans of Gbagbo who killed."

The 66-year-old Gbagbo, a history professor, came to power in a flawed election in 2000. He then failed to hold elections when his first five-year term expired in 2005, and rescheduled the vote a half-dozen times before it finally went ahead in 2010. Among conditions set by the international community, which Gbagbo accepted, were that the results would be certified by the United Nations in order to prevent his regime from rigging the vote.

But as soon as it became clear that Ouattara was leading in the polls, Gbagbo's presidential guard surrounded the election commission, preventing the results from being announced.

The killings began as soon as the United Nations declared Ouattara the winner, and for the next four months morgues overflowed as the military under Gbagbo's control executed opponents, gunned down protesters and shelled neighbourhoods.

The turning point came in March when thousands of unarmed women led a demonstration demanding Gbagbo's departure. Tanks opened fire with 50-calibre bullets and the horrific scene that followed was caught on camera phones, and led to condemnation by governments around the world, including U.S. Secretary of State Hillary Rodham Clinton.

The United Nations helped by French forces began air strikes soon after, clearing the path for Ouattara's soldiers to enter the city, where they seized Gbagbo inside his bunker.

"Today is a big day for the victims of crimes committed during Ivory Coast's horrific postelection violence," said Elise Keppler, senior counsel to Human Rights Watch in an email.

"While the Gbagbo camp fueled the violence through its refusal to relinquish power and its incitement, forces on both sides have been repeatedly implicated in grave crimes," she said. "The many victims of abuse meted out by forces loyal to President Ouattara also deserve to see justice done."

The spokesman for Ouattara's government Kone Bruno said he did not believe the pending indictment could destabilize the nation, which is still plagued by pockets of violence between the two camps. He added that the international court will likely be more impartial than an Ivory Coast court. "If a judgment were made in Ivory Coast, it wouldn't be objective," he said.

In the Netherlands, Gbagbo is likely to be better treated than he has been at home. His lawyer Altit said that while under house arrest in Korhogo the elderly Gbagbo was kept incommunicado and prohibited from going outside.

"He didn't have the right to walk even a few steps outside," said Altit. "At the beginning, he didn't have any clothes, and after two or two-and-a-half months lawyers were able to come see him and bring him some things."

A confidential United Nations document leaked to The Associated Press on Tuesday states that Gbagbo's health "seems to be deteriorating." He was having "trouble standing up," as of Nov. 23.

In The Hague, Gbagbo will likely be held in the same North Sea-facing complex that also houses ex-Liberian warlord Taylor and Congolese politician Jean-Pierre Bemba. Inmates have TVs, access to the Internet and a choice of books to read, as well as regular contact with their attorneys.
