Two weeks ago, military juntas controlling #Niger, #Mali, and #BurkinaFaso announced their countries' "immediate withdrawal" from #ECOWAS, #WestAfrica's regional integration bloc. This is a big deal.
The #ECOWAS treaty, which is incorporated into the laws of #Niger, #Mali, and #BurkinaFaso through past ratification, states in Article 91 that member countries can only withdraw from the organization after "one year's notice in writing".
Update: The #AfricanUnion has given the #Niger coup perpetrators until the middle of August to undo their coup, or face "extreme sanctions". That would presumably included suspending the country's #AU membership.
