A conservationist with dual French and Australian citizenship has been freed after he was taken hostage in Chad, interim president Mahamat Idriss Deby has announced.
Dr Jerome Hugonot, who manages an oryx park on behalf of a conservation group, was kidnapped on Friday by unknown individuals in the northeastern Wadi Fira province.
Deby announced his release on Twitter on Sunday without providing any details on how it was achieved.
"I am delighted with this happy ending," he said.
The French foreign ministry also announced the release in a separate statement.
"France thanks the Chadian authorities that worked for this release," the ministry said, also without giving further details.
