Burkina Faso has ordered the top UN official in the country to leave immediately.
The military government declared UN resident coordinator Barbara Manzi “persona non grata”.
Foreign Minister Olivia Rouamba said recent statements by the UN official warning of impending chaos caused by the Islamist insurgency had discredited Burkina Faso and put off potential investors.
The insurgency has already displaced nearly two million people, and prompted two military coups within a year.
Many of the displaced live in camps run by the UN.
