A communiqué from an unknown military commander in Guinea-Bissau says soldiers there have intervened to halt foreign aggression.
The statement was read on state radio on Friday, hours after the station’s transmission had been cut and explosions were heard throughout the capital.
It also was carried by the Portuguese news agency Lusa.
The body representing West African nations has called Thursday’s violence “a reprehensible coup attempt”.
The military commander claims that Prime Minister Carlos Gomes Jr. was going to allow Angolan troops inside Guinea-Bissau.
The violence comes just two weeks before the country’s scheduled presidential runoff vote.
