ABUJA, Nigeria (AP) _ Nelson Mandela's wife and South Africa's last white central bank head were among six people named Wednesday to Africa's first peer-review body, charged with pressing the continent's leaders to end war and corruption.

The Panel of Eminent Persons is part of a new program developed by South Africa, Senegal, Algeria and Nigeria to steer $6 billion in aid to countries whose governments are certified by the board as honest and accountable.

Nigerian officials said the program's goal was to put quiet pressure on African leaders to ensure peace and good governance.

The panel was selected during a meeting of heads of state in Nigeria's capital, Abuja, on the eve of Nigerian President Olusegun Obasanjo's inauguration to a second term.

The presidents also agreed to reinforce a multinational peacekeeping force in Ivory Coast with an unspecified number of troops and to create a standby force to respond to civil wars and other emergencies in the region.

The statement said the leaders also resolved to crack down on the trade and manufacture of light weapons and to ban the recruitment of mercenaries and disarm existing militias.

The regional bloc pledged to work with the United Nations on creating an international contact group to help bring peace to Liberia, a country wracked by civil war.

International leaders have imposed sanctions on President Charles Taylor's government, which is widely accused of fomenting conflicts at home and in neighboring Sierra Leone, Guinea and Ivory Coast.

African leaders are trying to show a commitment to good government in order to strengthen their case for increased aid when they meet with donor nations next month in France.

The peer panel includes Chris Staals, the former central bank governor, Mandela's wife Graca Machel, Nigerian economist Adebayo Adedeji, former Kenyan diplomat B.A. Kipglaat, Senegal's former U.N. official Marie-Angelique Savane and Cameroon's Dorothy Njeuma.

Some nations have expressed doubt the board would have the clout to effectively police abuses.

Earlier Wednesday, Obasanjo said African leaders ``should assure our developed partners ... of the African resolve'' to make peer review effective.

In return, he said, the Group of Eight richest nations should honor the commitment they made last year in Kananaskis, Canada, to increase aid to Africa, the world's poorest continent.

``It is high time the implementation of this plan took off in earnest,'' Obasanjo said.

Unless Western nations fulfill their commitments, Africa will remain unable to meet goals set at the Millennium Summit in New York in 2000 to dramatically improve education and health care.
