The 15-member Economic Community of West African States (ECOWAS) imposed economic sanctions after the Aug. 18 overthrow of President Ibrahim Boubacar Keita, and said a new president should be appointed by Tuesday.
But the junta pushed through a charter on Saturday that says the interim president can be a soldier or a civilian and has not yet indicated when the new government would be named.
Regional presidents met junta leaders on Tuesday in Ghana in an attempt to quicken the transition.
“Today is supposed to be the day that the junta is to put in place a government, which should respond to the criteria we set out in August. That has not been met,” said Ghana President Nana Akufo-Addo, the acting ECOWAS chair, before the start of talks.
Regional leaders fear the coup could set a dangerous precedent in West Africa and undermine a fight in Mali and neighboring countries in the Sahel region against Islamist militants with links to al Qaeda and Islamic State.
