A Gabonese government spokesman says all but one of the military officers who attempted a coup early Monday have been arrested.
"Four have been arrested and one is on the run," said Gabon spokesman Guy-Bertrand Mapangou.
Military officers seized Gabonese National Radio, the state radio station, Monday in Libreville, the capital.
The soldiers announced their intent to establish a national restoration council. Lieutenant Kelly Ondo Obiang said on the airwaves that President Ali Bongo's recent radio address "reinforced doubts about the president's ability to continue to carry out the responsibilities of his office."
The president is in Morocco, recovering from a stroke. Bongo became president in October 2009 after the death of his father who'd ruled Gabon from 1967 until 2009.
The French news agency AFP reports that shots were heard at the state television offices in the Libreville at the same time the military statement was being read on the radio.
U.S. President Donald Trump recently deployed American military personnel to Gabon because of fears on political unrest in neighbouring Congo.
