The African Union on Monday held talks on the Niger crisis as the country's post-coup rulers showed defiance yet also pointed to diplomacy for a potential solution.

But talks at the AU's headquarters in the Ethiopian capital Addis Ababa coincided with a flare-up over threats by the regime to prosecute Niger's deposed president.

"AU's Peace & Security Council meets to receive an update on the evolution of the situation in Niger and the efforts to address it," the pan-African body said in a post on X, formerly known as Twitter.
