The International Criminal Court has issued an arrest warrant for former Ivorian president Laurent Gbagbo's wife Simone, accusing her of being his "alter ego" in orchestrating a campaign of election violence almost two years ago in which 3,000 people died.

The warrant on four counts of crimes against humanity was issued in February but only made public by the court on Thursday and is the first issued by the ICC for a woman.

West African leaders at an emergency summit on Sunday agreed on a 3,300-strong force to wrest control of northern Mali from Islamist extremists as fears grow over risks they pose to the region and beyond.

The summit in the Nigerian capital Abuja was aimed at setting out a blueprint for military force in Mali's north that would be transferred to the U.N. Security Council via the African Union.

More than 200 people have been arbitrarily detained and tortured in Ivory Coast, Amnesty International said Friday, urging President Alassane Ouattara to respect human rights.

The victims included members of former president Laurent Gbagbo’s Ivorian Popular Front (FPI) who "have faced illegal detention and torture with many still languishing behind bars", Amnesty International said after a month-long mission to the west African country.

Morocco and the Ivory Coast on Friday signed an agreement on the exchange of information in the fight against money laundering and "financing terrorism," the official MAP news agency reported.

The accord was signed by Morocco's Financial Data Processing Unit (UTRF) and CENTIF-CI, the Ivory Coast finance ministry's unit for financial information, the agency said.

A solider and five assailants were on Saturday killed when a military checkpoint came under attack in southern Ivory Coast, a military source said, in the latest of a series of assaults.

"A checkpoint of the Republican Force (army) was attacked late morning at Irobo by men in a pick-up. A soldier was killed, another was injured and transferred to Abidjan. Five attackers were killed," the source told Agence France Presse.

The spokesman for former Ivory Coast president Laurent Gbagbo has been arrested in Ghana where he fled after the collapse of Gbagbo's regime, his family and a government source said Saturday.

Justin Kone Katinan was under an arrest warrant for alleged economic crimes as budget minister during the three months of crisis and conflict that followed Gbagbo's refusal to cede power to his rival Alassane Ouattara in December 2010.

A raid on an army base in Abidjan left at least six dead Monday, in the latest of a string of attacks targeting the military in the Ivory Coast economic capital.

President Alassane Ouattara has struggled to stabilize a country still awash with weapons and demobbed fighters, more than a year after the end of a deadly post-election crisis.

Gunmen attacked a police station and an army position in Abidjan Sunday, killing five soldiers, Defense Minister Paul Koffi Koffi told Agence France Presse.

Three members of the armed forces were killed in an attack on a police station in the Yopougon neighborhood and two others died in another attack on a nearby army position moments later, he said.

The International Criminal Court (ICC) said Friday it had postponed an August 13 hearing for former Ivory Coast president Laurent Gbagbo after defense lawyers questioned his fitness to stand trial.

Doctors could examine Gbagbo, 67, who faces charges of crimes against humanity, to determine if "he is fit to take part in the proceedings against him," the court said.

The United Nations scrambled Saturday to aid thousands who fled after at least 11 people died following ethnic violence and an attack on a U.N.-protected displaced persons camp in western Ivory Coast.

Friday's attack on the camp, which U.N. peacekeepers failed to stop, killed seven people, the United Nations said. Local sources however put the toll at nine in the camp.
