Authorities in Gabon say voters have overwhelmingly approved a new constitution more than one year after mutinous soldiers overthrew the country’s longtime president and seized power in the oil-rich Central African nation.

Gabon’s military rulers announced their new constitution had been overwhelmingly approved in a referendum, according to provisional results it published Sunday, marking a new chapter for the oil-rich African nation.

The constitutional change would also require presidential candidates to be exclusively Gabonese, with at least one Gabon- born parent and have a Gabonese spouse. The criterion disqualifies ousted ruler Ali Bongo Ondimba,
