Leaders of the 15-member Economic Community of West African States held an emergency summit in Ghana's capital Accra to agree a response to the Malian military's ouster of a president and prime minister for the second time in nine months.
Mali's neighbours and international powers fear the latest revolt will jeopardise a commitment to hold a presidential election next February, and undermine a regional fight against Islamist militants. In a communique after the summit, ECOWAS said Mali's membership in the bloc was suspended with immediate effect.
ECOWAS and Western powers including France and the United States worry the political crisis could exacerbate instability in northern and central Mali, a home base for regional affiliates of al Qaeda and Islamic State.
