Mali's interim President Dioncounda Traore says the international response to the crisis in his country shows the only way to resolve the situation is through unity and using all available resources.
He spoke Tuesday in Addis Ababa, where representatives of the African Union, United Nations and European Union gathered for a conference aimed at raising $500 million to support an African-led intervention force.
The call for aid comes as French and Malian troops continue their drive to recapture the north from Islamist rebels.
The African Union said it would give $50 million for the African-led International Mission to Mali (AFISMA). The West African bloc ECOWAS and South Africa each pledged $10 million, while others, including Ghana, Nigeria and Ethiopia, promised aid.
