On Tuesday, 18th, a group of military officers, calling themselves the National Committee for the Salvation of the People arrested Keita and other government officials, then made him resign, what he announced on the 19th, little after midnight. Now this junta is leading the country, according to them they are preparing for a new election, handing back the power to civil governance, in a reasonable time.
Internationally the coup was condemned by everyone ofc, from the Economic Community of West African States (since Mali is a member), through France, South Africa, the African Union, Algeria, Angola, Nigeria, Germany, Turkey, US, China, to the UN. They have to ofc be very concerned, there are some rules to play by, and ofc noone wants to get couped, no need to encourage those. As I read their comments, most of them don't really give a shit about Keita, they just urging to hold an election and get done with the military government asap.

It's easy to spot the parallels with the 2012 coup probably will play out similarly and Mali will return to the internationally sanctified constitutional ways. Heh, one article I read a fun comment, not sure now who said it, but went something like this: "referring to constitutionality is a bad argument, anti-constitutional events happen all over Africa all the time, they are going right now and noone cares" (this isn't an exact quote ofc).
I see an interesting contrast. President Keita is 75 years old, while the group of officers are kinda low ranking (colonel and below) and young ones. The leader of the junta, Colonel Assimi Goita is said to be 37.
