Burkina Faso and Niger have followed Mali in announcing they are to withdraw from an international force known as the G5 that was set up to fight Islamists in the Sahel region.
All three countries are run by military rulers following coups who have formed their own mutual defence pact.
A statement from the military-led governments of Burkina Faso and Niger was critical of the G5 force for failing to make the Sahel region safer.
It also suggested the anti-jihadist force undermined the two African nations' desire for greater independence and dignity and was serving foreign interests instead. They almost certainly meant France.
Relations with the former colonial power have dramatically deteriorated.
