Speaking after meeting Senegalese President Macky Sall in Dakar, he said they had agreed on the need to keep talking to the de facto authorities in all three countries so as to get a swift return to "constitutional order".

All three countries, struggling with a jihadist insurgency in the Sahel region, have recently experienced military coups: Mali in August 2020 and May 2021; Guinea in September 2021; and Burkina Faso in January 2022.

Sall is the current chair of the West African bloc ECOWAS, which imposed heavy sanctions against Mali in January after the regime there rejected a rapid return to civilian rule.

It has threatened similar sanctions against Guinea and Burkina Faso if they fail to enable a swift transition to civilian rule within a "reasonable" timeframe.
